At LensFactory, we offer a range of lens options to fit your lifestyle, prescription, and budget. In this post, we’ll break down the differences between common lens materials and help you decide which one is best for you.

Lens Materials Overview

Let’s take a closer look at the most popular prescription lens materials on the market today:

1. Standard Plastic

Best for: Low prescriptions, budget-conscious users

• Lightweight and affordable

• Good optical clarity

• Limited durability and thickness with stronger prescriptions

Worth noting:*Standard plastic is a solid choice if your prescription is mild and you’re looking for the most economical option.

2. Polycarbonate

Best for: Active lifestyles, kids, rimless or semi-rimless frames

• Impact-resistant and lightweight

• Built-in UV protection

• Slightly less optical clarity than CR-39 but more durable

Why it matters:*Polycarbonate lenses are 10x more impact-resistant than standard plastic—perfect for sports, work environments, and everyday wear.

3. Trivex

Best for: Those who want a balance of clarity, durability, and comfort

• Even lighter than polycarbonate

• Excellent impact resistance

• Superior optical clarity

Bonus: Trivex lenses offer better visual clarity and less distortion compared to polycarbonate, while still providing the same rugged durability.

4. High-Index Plastic

Best for: Strong prescriptions, style-conscious users

• Ultra-thin and lightweight

• Reduces lens thickness for stronger prescriptions

• Available with all premium coatings

Why you’ll love it: High-index lenses are the most discreet option. If you hate the “coke bottle” look, these are your best bet for slim, comfortable eyewear.

Which Lens Material Should You Choose?

Here’s a quick guide:

LensFactory’s Expert Tip:

Don’t forget the coatings! Regardless of material, adding anti-reflective, scratch-resistant, and blue light coatings can make a huge difference in comfort and performance—especially if you spend time on screens or drive at night.

Why Lens Material Matters

Choosing the right lens material is about more than just prescription strength. It affects:

• How your glasses feel on your face

• How clearly you see throughout the day

• How durable your lenses are*against drops, scratches, or pressure

At LensFactory, we help you match your lens material to your lifestyle—whether you're a student, athlete, professional, or just someone who wants to enjoy clearer, more comfortable vision every day.

At LensFactory, we believe smart choices should benefit both your lifestyle and the environment. Let’s explore why lens replacement is the sustainable and budget-friendly solution you've been waiting for.

The Environmental Case for Replacing Your Lenses

1. Less Waste in Landfills
Over 4 million pairs of glasses are discarded in the U.S. each year. Most of them still have functional frames. That’s a lot of plastic and metal going straight to the landfill. By keeping your frames and replacing just the lenses, you're reducing your environmental footprint.

2. Reduce the Demand for New Manufacturing
Every new pair of glasses requires raw materials—plastic, metal, screws, nose pads—and energy-intensive production. Choosing lens replacement means you're not contributing to the cycle of overproduction and overconsumption.

3. Sustainable Style
Have a favorite pair of vintage frames or a designer set that fits just right? Don’t toss them. Refresh them with new lenses and extend their lifespan by years. Less buying, less waste—and you still look great.

The Financial Benefits Are Just as Clear

1. Save Up to 70% Compared to Buying New Glasses
Buying new prescription glasses—especially with specialty lenses or coatings—can cost anywhere from $200 to $800. At LensFactory, replacing your lenses can cost as little as $77, depending on your prescription and lens type.

2. Upgrade Without the Extra Fees
Many optical retailers bake hidden costs into new glasses: designer markups, frame upsells, insurance add-ons, etc. When you send your existing frames to LensFactory, you pay only for the lenses and coatings you actually need.

3. More Customization for Less
Lens replacement lets you select exactly the right features: blue light blocking, anti-reflective coatings, UV protection, photochromic lenses, and more. All without overpaying at a retail store.

Who Should Replace Their Lenses?

• Anyone with updated prescriptions but frames they still love
  

• Budget-conscious shoppers tired of overpriced optical stores
  

• Eco-conscious consumers looking to reduce waste
  

• Collectors and style lovers with designer or unique frames
  

• Seniors or students with fixed incomes and evolving vision needs
  

If any of these sound like you, lens replacement may be your perfect match.

Common Causes of Scratched Lenses

Scratched lenses can occur due to a variety of reasons, including:

• Improper cleaning techniques
• Dropping your glasses
• Storing them without a case
• Exposure to harsh chemicals

DIY Methods to Remove Scratches from Glasses

Disclaimer! These suggestions should be treated as a last-ditch effort. It's possible that these methods could remove lens coatings or slightly warp your lenses - which would be a problem with correctional lenses.

Toothpaste Method

One common method is using non-abrasive toothpaste:

1. Apply a small amount of toothpaste to the scratched area.
2. Rub gently in a circular motion with a soft cloth.
3. Rinse with cool water and dry with a microfiber cloth.

Baking Soda Paste

Another option for removing scratches from lenses is a baking soda paste:

1. Mix baking soda with water to form a thick paste.
2. Apply the paste to the scratches and rub gently.
3. Rinse and dry the lenses.

Glass Etching Cream

For deeper scratches, glass etching cream might be effective:

1. Apply a small amount of the cream to the scratched area.
2. Leave it on for a few minutes.
3. Rinse off thoroughly and dry.

If DIY methods don't work or if the scratches are too deep, it's best to seek professional help. Here at LensFactory, we specialize in replacing scratched or damaged lenses in your existing frames.

FAQs

Can toothpaste really remove scratches from glasses?

Possibly. A non-abrasive toothpaste can help with very minor scratches by polishing the surface. However, most scratches will probably be too deep for toothpaste to make any noticeable difference.

Is it safe to use baking soda on lenses?

Baking soda is a mild abrasive that can help with surface scratches. Be aware, it can also remove other coatings on your lenses.

• UV Protection: Our lenses provide advanced UV protection, shielding your eyes from harmful rays and reducing eye fatigue during long drives.

Factors to Consider When Choosing Driving Lenses

Choosing the right lenses can make a world of difference in your driving experience. Here are some factors to consider when looking for good glasses for night driving:

• Polarized vs. Non-Polarized: Polarized lenses are ideal for cutting glare from reflective surfaces like wet roads or car hoods. Non-polarized lenses, on the other hand, are a better fit if you require prescription lenses or frequently use digital devices while driving.
• Lens Tint & Color: The tint and color of your lenses can impact your driving visibility. In general, brown or grey tints are good driving lenses, because can help visibility of traffic lights or brake lights. Gray tints are great for maintaining true color perception, while yellow or amber tints can enhance contrast and depth perception, especially in low-light or foggy conditions.
• Lens Coatings: Anti-reflective coatings minimize glare and internal reflections. Scratch-resistant coatings protect your lenses from daily wear and tear.

The Value of Driving Lenses During the Day and Night

Driving conditions vary throughout the day and night, and having the right lenses is more than helpful. Our lenses are designed to perform exceptionally well in different lighting conditions:

Lenses for Day Driving

Our lenses offer superior clarity and contrast during the day, reducing glare from the sun and enhancing visibility in bright conditions. You might also consider a gray coating when the weather is sunny and bright. A neutral shade is the least disruptive to your natural color vision.

Additionally, since neutral shades are some of the densest lens colors, they can absorb a higher percentage of light. This means that you’ll receive maximum sun protection and won’t have to squint as much while driving.

Lenses for Night Driving

With advanced anti-glare technology, our lenses minimize halos and reflections from oncoming headlights, providing clear vision and reducing eye fatigue during nighttime driving, making them the best eye glasses for night driving.

Benefits of Driving Glasses

Investing in the right pair of driving glasses offers more than just clear vision. Here's how our lenses can further enhance your driving experience:

• Improved Night Vision: Our lenses optimize light transmission, reducing glare and enhancing visibility during nighttime driving, making them the best eye glasses for night driving.
• Reduced Glare: Advanced coatings minimize reflections, ensuring a glare-free drive and reducing eye strain, especially when you're looking for good glasses for night driving.
• Customizable Options: Personalize your lenses with various coatings and tints tailored to your preferences for the ultimate driving experience with the best lenses for driving.

Tailored specifically for pilots, these lenses incorporate cutting-edge design and technology to enhance visual performance in the cockpit.

Fly smarter and safer with pilot lenses.

Pilot Progressive vs. Traditional Progressive Lenses

Progressive lenses have long been favored for their ability to correct vision at multiple distances seamlessly. Traditionally, the upper portion of the lens focuses on distant objects, while the lower portion aids in near vision.

However, for wearers who need to focus on near objects through the upper part of the lens, this standard configuration falls short.

How do Pilot Progressive Lenses differ from traditional progressive lenses?

Pilot progressive lenses redefine the traditional progressive design.

Traditional progressive lenses focus on distant objects in the upper part of the lens and near objects in the lower part.

Pilot progressive lenses offer an additional segment for near vision at the top, providing wearers with improved versatility and clarity, especially when glancing upward.

Pilot lenses minimize oblique aberrations, ensuring superior personalized lens performance with near-elimination of peripheral blur.

This innovative architecture provides pilots with enhanced flexibility and clarity.

Advanced Technology for Superior Performance

Endless Pilot Progressive lenses integrate IOT Digital Ray-Path 2 Technology, a cutting-edge advancement that revolutionizes personalized lens design.

By intelligently incorporating the wearer’s accommodation into traditional calculations, this technology minimizes oblique aberrations more effectively than ever before.

Whether scanning instruments, reading charts, or focusing on controls, wearers can trust in the precision and clarity of these lenses.

Lenses Designed for Pilots, Engineered for Excellence

Endless Pilot Progressive lenses are categorized under Camber Steady Plus Progressive, making them ideal for pilots who require an additional near power zone in the upper portion of the lens.

Whether wearers have mild or complex prescriptions, these lenses accommodate a wide range of needs with ease.

Wildly Compatible

Compatibility is key in aviation eyewear, and Endless Pilot Progressive lenses do nothing short of excel.

Compatible with any blank provider, lens index, coatings, machinery supplier, and LMS, these lenses offer versatility and convenience without compromise. 

Comfortable and High Performance Lenses for Pilots

The benefits of pilot lenses, which have precise near vision in both the upper and lower areas of the lens, extend far beyond traditional eyewear solutions.

• Fewer unnecessary head movements
• Less visual strain
• Optimal ergonomics
• Effortless transition between different viewing areas
• Greater comfort and crisp, clear vision

Personalization for Maximum Performance

Pilot progressive lenses can be further personalized to suit the unique needs and frames of the wearer.

A complete set of individualization parameters ensures optimal performance and comfort, tailored to specific preferences and needs.

Compensated power calculation guarantees wearers perceive the correct power at every distance and direction of gaze, including when viewing electronic devices up close.

Meanwhile, optimized accommodative object space minimizes oblique aberrations, resulting in consistent, stable power distribution regardless of prescription or frame style.

Handle Your Lenses with Care

Replace Your Lenses Regularly

Prevent Your Lenses from Damage

However, over a period of time, the lenses in your eyeglasses can become worn out or damaged, leading to a decline in visual acuity and comfort.

It is essential to acknowledge when to replace your prescription eyeglass lenses to ensure optimal vision and prevent eye strain and discomfort.

Here are some common signs that it may be time to replace your prescription lenses:

1) Blurred Vision

One of the most obvious signs that you need new prescription eyeglass lenses is blurred vision.

Blurry vision can occur when your current lenses are scratched, pitted, or damaged. These imperfections can interfere with the clarity of your vision and make it difficult to see things clearly.

Blurred vision can also occur when your current lenses are no longer strong enough to correct your vision. Over time, your eyes can change, and your current prescription may no longer be effective in providing you with the sharp vision you need.

If you are experiencing blurred vision, schedule an eye exam with your optometrist. Your optometrist can determine if your current prescription needs to be adjusted or if new eyeglass lenses are needed.

2) Eye Strain

Eye strain is a common problem for people who spend long hours reading, using a computer, or watching television. However, if you are experiencing eye strain more frequently, it could be a sign that you need new prescription lenses.

Old or damaged lenses can cause your eyes to work harder to focus, leading to strain and fatigue. New lenses can reduce the weariness of your eyes and help you feel more comfortable while reading or using a computer.

3) Headaches

If you are undergoing recurring headaches, it could be a sign that you need new prescription eyeglass lenses. When your current lenses are no longer effective in correcting your vision, your eyes can become strained, leading to headaches and migraines.

Headaches can also occur when your prescription is inaccurate, causing your eyes to work harder to focus. Receiving a routine eye exam and new lenses can help diminish the commonness and intensity of headaches.

4) Scratches and Damage

5) Discoloration

6) Warped Frames

If your eyeglass frames have become warped or bent, it can affect the fit and alignment of your lenses. Warped frames can cause your lenses to become misaligned, leading to visual distortion and discomfort.

Replacing or adjusting your frames can ensure your lenses are properly aligned and provide the best possible vision correction.

Reading Your Prescription

Your eyeglass prescription is a written statement by your eye care professional that specifies the corrective lenses needed to correct your vision. It contains a series of numbers and abbreviations that may seem confusing initially, but it's essential to understand what each means to ensure you get the right lenses for your needs.

OD and OS

The first two terms you will encounter on your prescription are OD and OS, which stand for "oculus dexter" and "oculus sinister," respectively. These terms are Latin for "right eye" and "left eye." Your prescription will list the parameters for each eye separately. Sometimes, the abbreviation "OU" may be used instead of OD and OS, which stands for "oculus uterque," meaning "both eyes."

Sphere (SPH)

The sphere (SPH) value is the primary correction for nearsightedness (myopia) or farsightedness (hyperopia) and is measured in diopters (D). A negative value indicates nearsightedness, while a positive value indicates farsightedness. The further from zero, the more severe the condition.

Cylinder (CYL)

The cylinder (CYL) value indicates the degree of astigmatism, which means that the cornea is shaped more like a football than a sphere. Astigmatism can cause blurry or distorted vision. The cylinder value is also measured in diopters and can be positive or negative. If there is no cylinder value, it means you don't have astigmatism.

Axis

The axis is a number between 0 and 180 degrees that indicates the orientation of the astigmatism. The axis is only present if there is a cylinder value.

Add

The "add" value is a measure of the additional power required for reading or close work. It is a positive number and is only present in bifocal, trifocal, or progressive lens prescriptions.

Choosing the Correct Lenses for Your Prescription

Once you understand the various parameters in your prescription, it's time to choose the right lenses for your needs. At LensFactory, we offer a range of lens materials and designs, including plastic, poly, high index, or glass lenses, as well as single vision, bifocal, trifocal, progressive, and non-Rx lenses.

Lens Materials

Plastic Lenses

Plastic lenses are the most common type of eyeglass lenses, as they are lightweight, impact-resistant, and easy to care for. They are also less expensive than other materials. However, they are thicker than other materials and may not be suitable for higher prescriptions.

Polycarbonate Lenses

Polycarbonate lenses are a type of plastic lens that is even more impact-resistant than regular plastic lenses. They are also thinner and lighter, making them a good choice for people with higher prescriptions or for children's glasses. They are more expensive than regular plastic lenses but offer better protection.

High Index Lenses

High-index lenses are made of a special material that bends light more efficiently than plastic or glass lenses. As a result, they can be made thinner and lighter, making them a good choice for people with high prescriptions who want a more aesthetically pleasing lens. They are more expensive than other materials, but they present better optics.

Glass Lenses

Glass lenses were once the most common type of eyeglass lenses, but they have become less popular due to their weight and fragility. They are still an option, though, and they offer excellent optics. They are also scratch-resistant and provide a clear image. However, they are not recommended for active people or children due to their fragility.

Lens Designs

Single-Vision Lenses

Single-vision lenses have the same prescription throughout the entire lens and are used to correct nearsightedness, farsightedness, or astigmatism. They are the simplest type of lenses and the most affordable.

Bifocal Lenses

Bifocal lenses have two prescriptions in one lens, separated by a visible line. The top portion of the lens is for distance vision, while the bottom portion is for near vision. Bifocal lenses are a good choice for people with trouble seeing objects up close or needing help reading.

Trifocal Lenses

Trifocal lenses have three prescriptions in one lens, separated by two visible lines. The top portion of the lens is for distance vision, the middle portion is for intermediate vision, and the bottom portion is for near vision. Trifocal lenses are a good choice for people who need help seeing objects at different distances.

Progressive Lenses

Progressive lenses have a gradual transition from distance to near prescriptions, with no visible line. They provide a more natural vision experience than bifocal or trifocal lenses, and they are a good choice for people who need help with both distance and near vision. However, they are more expensive than other types of lenses.

Non-Rx Lenses

Non-Rx lenses, also known as plano lenses, have no prescription and are used for fashion or as protective eyewear. They can be made in any lens material or design and can include features such as UV protection, polarization, or scratch resistance.

Choosing the Right Lens Options

In addition to the lens material and design, there are several lens options to consider when selecting your lenses.

Anti-Reflective Coating

Anti-reflective (AR) coating reduces glare and reflections on the lens surface, improving visual acuity and reducing eye strain. It also makes the lenses appear clearer and less noticeable. AR coating is recommended for people who spend a lot of time in front of a computer or under artificial lighting.

UV Protection

UV protection blocks harmful UV radiation from the sun, reducing the risk of eye damage and vision loss. UV protection is essential for people who spend a lot of time outdoors or who are exposed to UV radiation from artificial sources, such as tanning beds.

Polarization

Polarization reduces glare and improves visual clarity by filtering out light that is reflected off flat surfaces, such as water, snow, or pavement. Polarized lenses are recommended for people who spend a lot of time outdoors, especially around water or snow.

Photochromic

Photochromic lenses darken in bright light and lighten in low light, providing automatic protection from glare and UV radiation. Photochromic lenses are a good choice for people who frequently transition between indoor and outdoor environments.

In summary, choosing the right lenses for your eyeglasses is essential for maintaining good vision and preventing eye strain or damage. Understanding your prescription and the different lens options available can help you make an informed decision. At LensFactory.com, we offer a range of lens materials, designs, and options to suit your needs and budget. Whether you need single vision, bifocal, trifocal, progressive, or non-Rx lenses, we can provide you with high-quality, affordable replacement lenses.

In a world filled with captivating sights and precious moments, our eyes are the gateway to experiencing everything that surrounds us.

But in the midst the hustle and bustle of daily life, it's all too easy to overlook the treasure that is healthy eyesight.

As we age, our eyes inevitably become more vulnerable to health issues. From the persistent discomfort of dry eyes to the insidious threat of cataracts and even the potential loss of sight, our eyes demand our unwavering attention and care.

The good news is there are steps you can take to maintain your eye health and reduce your risk of developing these conditions.

How To Maintain Good Eye Health

We have five methods to share that will help to preserve the well-being of your eyes! By incorporating these practices into your daily routine, you can protect your vision.

1. Eat a healthy diet.
2. Protect your eyes from the sun and UV rays.
3. Take frequent breaks from digital devices and screens.
4. Get a regular eye exam.
5. Replace your lenses regularly.

1) Eat a healthy diet.

Eating a healthy diet is one of the most effective ways to maintain your overall health, including your eye health. Certain nutrients, such as omega-3 fatty acids, lutein, zinc, and vitamins C and E, are particularly beneficial for your eyes.

These nutrients can help protect against age-related macular degeneration, cataracts, and other eye conditions.

To get these nutrients, incorporate into your diet foods like:

• Dark, leafy greens like spinach and kale
• Fatty fish like salmon and tuna
• Citrus fruits
• Legumes/Beans
• Eggs
• Oysters
• Pork

If you're having trouble getting enough of these nutrients from your diet alone, consider taking a multivitamin or a supplement specifically designed for eye health.

There are several supplements that have shown potential benefits for eye health. We are not endorsing any supplement, and supplements should not replace a healthy diet or proper medical care.

That said, here are a few supplements that are often recommended for eye health:

• Omega-3 Fatty Acids: These essential fatty acids are found in oily fish like salmon, tuna, and sardines, as well as in flaxseeds and chia seeds. Omega-3 fatty acids are believed to help prevent dry eyes and reduce the risk of age-related macular degeneration (AMD).
  
  
• Lutein and Zeaxanthin: These antioxidants are found in high concentrations in the macula of the eye and are believed to help filter harmful blue light and reduce the risk of AMD and cataracts. Good dietary sources include dark leafy greens like spinach and kale, as well as yellow and orange fruits and vegetables.
  
  
• Vitamin C: This antioxidant is known to support overall eye health. It can be found in citrus fruits, berries, and various vegetables like bell peppers and broccoli.
  
  
• Vitamin E: Another antioxidant, vitamin E, may help protect cells in the eyes from oxidative stress. Nuts, seeds, and vegetable oils are good sources of vitamin E.
  
  
• Zinc: This mineral plays a vital role in eye health and is concentrated in the retina. It can be obtained from seafood, lean meats, whole grains, and legumes.

2) Protect your eyes from the sun.

Just like your skin, your eyes can be damaged by the sun's UV rays.

This can lead to a range of issues, from temporary discomfort to long-term damage and even blindness. Too much UV exposure can increase chances of cataracts and macular degeneration.

To protect your eyes from UV rays, wear sunglasses that block 99% to 100% of both UVA and UVB rays.

Look for sunglasses with polarized lenses, also. These reduce glare and make it easier to see in bright sunlight.

And don't forget to wear a wide-brimmed hat or visor to provide extra shade for your eyes if you're going to have prolonged exposure to sunlight.

You might think you look goofy wearing the hat. But you'll look a lot more goofy when you're bumping into walls because your eyesight is damaged 😆

3) Take regular breaks when using digital devices.

It's not uncommon to spend hours each day staring at a computer, phone, or tablet.

If you're an iPhone user, pull your phone out and check the screen time reporting. It's okay, we won't judge too harshly...we all do it!

Unfortunately, all this screen time can have negative impacts on your eye health.

• Reduced Blinking: When we focus on screens, we tend to blink less frequently, leading to dry and irritated eyes. Normal blinking helps to lubricate the eyes and prevent dryness.
  
  
• Myopia (Nearsightedness): Studies have shown a correlation between increased screen time and the development or progression of myopia, particularly in children and adolescents. The exact mechanism is not fully understood, but it is believed that excessive near work and limited outdoor activities play a role.
  
  
• Increased Sensitivity to Contrast: Staring at screens for extended periods can make it more challenging for our eyes to adjust to different contrasts, such as when transitioning from a bright screen to a darker environment.

The 20-20-20 rule is a good guideline to follow: every 20 minutes, take a 20-second break and look at something 20 feet away.

This can reduce eye strain and gives your eyes a chance to rest and recover.

Does reducing screen time improve eyesight?

Reducing screen time alone may not directly improve eyesight or reverse existing vision problems. But reducing screen time can slow down progression of certain conditions or ease symptoms in the moment.

4) Get regular eye exams.

Regular eye exams are crucial for maintaining your eye health, especially as you get older. During an eye exam, your eye doctor can detect early signs of eye diseases and conditions that may not have symptoms yet.

Depending on your age and medical history, your eye doctor may recommend different frequencies for your eye exams.

In general, adults should have a comprehensive eye exam every two years, or more often if they have a history of eye problems or other health issues.

5) Replace your lenses regularly at LensFactory.

If you wear prescription glasses, it is important to replace the lenses regularly to maintain your eye health.

Over time, lenses can become scratched, damaged, or accumulate dirt and debris, which can affect your vision and cause eye strain or headaches.

At LensFactory, we offer a convenient and affordable way to order replacement lenses for your glasses.

Our online ordering system makes it easy to choose from a variety of lens types and prescriptions, and we offer fast and reliable shipping to ensure you receive your lenses quickly.

By replacing your glasses lenses regularly, you can ensure that your vision remains clear and comfortable.

Plus, with LensFactory, you can do so without breaking the bank. We offer high-quality lenses at competitive prices, so you can prioritize your eye health without sacrificing your budget.

The Importance of Eye Exams

Eye exams are not only essential for evaluating your vision but also for detecting early signs of eye diseases and other underlying health conditions. Regular exams can help identify conditions like glaucoma, cataracts, macular degeneration, and diabetic retinopathy. Early detection allows for prompt treatment, preserving your vision and overall eye health.

What to Expect at an Eye Exam (700 words)

• Case History: Your optometrist will review your medical history and inquire about any specific vision concerns or symptoms you may be experiencing.
• Visual Acuity Testing: This test measures the sharpness and clarity of your vision using an eye chart. You will be asked to read letters or symbols from a distance to determine the level of visual acuity.
• Refraction Assessment: The optometrist will use a series of lenses to determine the most accurate prescription for correcting any refractive errors, such as nearsightedness, farsightedness, or astigmatism.
• Ocular Health Evaluation: The optometrist will examine the health of your eyes using various instruments, including a slit lamp, to assess the cornea, iris, lens, and other structures. This evaluation can help identify any abnormalities or signs of eye diseases.
• Intraocular Pressure Measurement: Elevated intraocular pressure is a potential sign of glaucoma. The optometrist may use a tonometer to measure the pressure inside your eyes and screen for this condition.
• Pupil Dilation: In some cases, your optometrist may choose to dilate your pupils using eye drops to gain a better view of the internal structures of your eyes, such as the retina and optic nerve.
• Additional Tests: Depending on your specific needs, the optometrist may perform additional tests, such as visual field testing, color vision testing, or assessing your depth perception.

Cataract Surgery Procedure

Cataract surgery is typically an outpatient procedure performed under local anesthesia. The surgeon makes a small incision in the cornea, removes the clouded lens using ultrasound energy (phacoemulsification), and inserts a clear IOL in its place. This IOL replaces the natural lens, enabling light to focus properly on the retina and restore clear vision.

Lens Replacement Scenarios

While cataract surgery generally provides long-lasting visual improvement, there are instances where lens replacement may be required:

• Posterior Capsular Opacification (PCO): In some cases, the back part of the lens capsule that holds the IOL becomes cloudy over time, causing blurred vision similar to cataract symptoms. A simple laser procedure called YAG capsulotomy can usually clear the cloudiness and restore vision without the need for lens replacement.
• Refractive Errors: After cataract surgery, some patients may experience residual refractive errors, such as nearsightedness, farsightedness, or astigmatism. In these cases, lens replacement with a specialized IOL, such as a toric or multifocal lens, can correct the refractive error and enhance visual acuity.
• Dissatisfaction with Visual Outcome: Occasionally, patients may not achieve their desired visual acuity following cataract surgery. This may be due to factors like inaccurate lens power calculation or pre-existing ocular conditions. In such cases, lens replacement may be considered to improve the visual outcome.

 Post-operative Care and Lens Replacement

After cataract surgery, proper post-operative care is essential to ensure optimal healing and visual recovery. Patients should follow their surgeon's instructions regarding the use of eye drops, avoiding strenuous activities, and protecting the eyes from irritants. Regular follow-up visits allow the surgeon to monitor healing progress and address any concerns.

In cases where a lens replacement is necessary, the decision is made after careful evaluation by the surgeon. Factors such as the patient's overall eye health, degree of refractive error, and personal preferences are taken into consideration. The surgeon will discuss the available options and guide the patient in choosing the most suitable replacement lens.

Factors Influencing Prescription Lens Replacement

The decision to replace glasses lenses after cataract surgery depends on several factors:

• Refractive Errors: Cataract surgery primarily corrects the clouding of the natural lens, but it may not fully address pre-existing refractive errors. Patients with residual nearsightedness, farsightedness, or astigmatism may need glasses with updated prescriptions to optimize their vision after surgery.
• Presbyopia: Presbyopia, the age-related loss of near vision, affects most individuals in their 40s or 50s. Cataract surgery may not eliminate the need for reading glasses, especially for individuals who have reached or are approaching this stage of life. Glasses with progressive lenses or bifocal/trifocal lenses can help address presbyopia and provide clear vision at various distances.
• Individual Preferences and Activities: Some patients may opt for glasses lens replacement to enhance their visual comfort and convenience, particularly if they have specific hobbies or professions that require precise vision. Customized lenses, such as those designed for computer use or sports activities, can be fitted into existing frames to cater to individual needs.

Optimizing Visual Acuity with Prescription Lens Replacement

To obtain the best visual outcome with glasses lens replacement after cataract surgery, it is essential to consult with an optometrist or ophthalmologist experienced in post-cataract vision correction. These professionals will perform a comprehensive eye examination and determine the most appropriate prescription for your glasses lenses.

When considering glasses lens replacement, it is advisable to:

• Consult an Eye Care Professional: Seek guidance from an eye care specialist who can assess your visual needs and recommend the most suitable lens options based on your unique requirements.
• Update Your Prescription: Ensure that your glasses prescription accurately reflects your visual needs after cataract surgery. Regular eye exams will help identify any changes in your vision that may necessitate lens replacement.
• Consider Lens Coatings: Explore lens coating options, such as anti-reflective coatings or blue light filters, to enhance visual comfort and protect your eyes during prolonged computer use or exposure to digital screens.

After undergoing cataract surgery, glasses lens replacement may be necessary to address residual refractive errors or presbyopia. LensFactory emerges as the go-to destination for obtaining top-quality replacement lenses. With their wide selection of lenses, customization options, commitment to quality, and user-friendly online ordering system, LensFactory ensures that you can find the perfect lenses to optimize your vision after cataract surgery.

Causes and Solutions for Bad Eyesight

Bad eyesight can be caused by various factors, such as refractive errors (nearsightedness, farsightedness, astigmatism), age-related conditions (presbyopia), environmental factors such as diet and phone use, and eye diseases (cataracts, glaucoma)

Genetic Factors and Development of Bad Eyesight

Genetics can indeed play a role in the development of bad eyesight, as certain eye conditions have a hereditary component. Individuals with a family history of conditions like myopia (nearsightedness), hyperopia (farsightedness), astigmatism, or certain eye diseases may have an increased risk of developing these conditions themselves.

While genetics can contribute to bad eyesight, environmental factors and lifestyle choices also play a significant role. Environmental factors such as prolonged near work, excessive screen time, and inadequate lighting can strain the eyes and contribute to the development or progression of refractive errors. Additionally, lifestyle choices such as poor nutrition, smoking, and lack of physical activity can impact overall eye health.

Regular eye exams are crucial for individuals with a genetic predisposition to bad eyesight. Eye exams can detect and monitor inherited eye conditions, allowing for early intervention and appropriate management. Optometrists can prescribe corrective lenses or recommend other vision correction methods to optimize visual acuity and minimize the impact of inherited eye conditions on daily life.

By understanding the interplay between genetics, environmental factors, and lifestyle choices, individuals can make informed decisions to protect and maintain their vision. Proactive measures such as regular eye exams, adopting healthy visual habits, and making lifestyle changes when necessary can help mitigate the impact of genetic predisposition and promote optimal eye health.

Impact of Phones and Screen Time on Eyesight

Excessive screen time has become a common part of our modern lifestyle, and it can take a toll on our eyes. The blue light emitted by digital devices, such as smartphones, tablets, and computer screens, can contribute to eye strain and discomfort. Prolonged exposure to this blue light has been associated with potential vision problems, including digital eye strain, dryness, blurred vision, and headaches.

To reduce eye strain caused by screens, it is important to implement practical tips and habits. Maintaining an appropriate viewing distance by keeping the screen at arm's length and slightly below eye level can help alleviate strain. Following the 20-20-20 rule is also beneficial—take a break every 20 minutes and focus on an object about 20 feet away for at least 20 seconds. This gives your eyes a chance to rest and readjust.

Adjusting screen settings to reduce brightness and minimize blue light emission can be helpful. Most devices offer options to reduce blue light, such as Night Shift or Night Mode. Alternatively, using blue light filters or wearing specialized glasses with blue light-blocking coatings can provide additional protection.

Incorporating regular eye breaks, practicing good ergonomics, and ensuring proper lighting in the surrounding environment are other effective measures to reduce eye strain. Additionally, maintaining a balanced lifestyle that includes physical activity, proper hydration, and a healthy diet can support overall eye health and reduce the impact of screen-related eye strain.

By implementing these practical tips, individuals can minimize the negative effects of excessive screen time and protect their eyes from the potential vision problems associated with prolonged screen exposure. It is essential to be mindful of our screen habits and prioritize healthy visual practices in our daily routines.

Early Signs, Blurry Vision, and Natural Vision Improvement

Recognizing the early signs of bad eyesight is crucial for timely intervention and effective management. Some common indicators include frequent headaches, eye fatigue, difficulty reading, and problems with focusing. Blurry vision is another significant symptom that may indicate the presence of refractive errors or other underlying eye conditions.

Understanding the causes of blurry vision can help individuals make informed decisions about seeking professional eye care. Refractive errors such as myopia, hyperopia, and astigmatism can cause blurry vision at different distances. Eye conditions like dry eye syndrome, cataracts, or glaucoma can also contribute to blurred vision.

Seeking professional eye care is essential to determine the root cause of blurry vision and receive appropriate treatment. Optometrists can conduct comprehensive eye exams, diagnose any underlying conditions, and prescribe corrective lenses or recommend other suitable interventions. Regular eye exams also enable early detection of eye diseases, providing an opportunity for timely management and prevention of vision loss.

While professional eye care is vital, individuals can also explore natural methods to support vision improvement. Eye exercises, relaxation techniques, and practicing good visual habits can help strengthen eye muscles and alleviate eye strain. Maintaining a healthy lifestyle through a balanced diet rich in nutrients beneficial to eye health, regular exercise, and adequate hydration can also contribute to overall visual well-being.

By recognizing the early signs of bad eyesight and seeking professional eye care, individuals can address vision issues promptly and prevent further deterioration. Incorporating natural methods for vision improvement as part of a healthy lifestyle can complement professional care and contribute to long-term eye health and clarity of vision.

Vitamin Deficiencies and Diet for Vision Health

Maintaining good eyesight relies on various factors, including proper nutrition and vitamin intake. Certain vitamins and minerals play a crucial role in supporting vision health. Vitamin A is essential for the functioning of the retina and low levels can lead to night blindness and dry eyes. Citrus fruits, leafy greens, and carrots are rich sources of vitamin A.

• Vitamin C acts as an antioxidant, protecting the eyes from damage caused by free radicals. It also supports the health of blood vessels in the eyes. Citrus fruits, bell peppers, and strawberries are excellent sources of vitamin C.
• Vitamin E is another powerful antioxidant that helps protect the eyes from oxidative stress. Nuts, seeds, and vegetable oils are great sources of vitamin E.
• Zinc is important for the metabolism of vitamin A and plays a role in maintaining the health of the retina. Seafood, lean meats, and legumes are good sources of zinc.
• Omega-3 fatty acids, particularly DHA (docosahexaenoic acid), are crucial for maintaining the structure and function of the retina. Cold-water fish like salmon, sardines, and trout are rich sources of omega-3 fatty acids.

A balanced diet that incorporates these nutrient-rich foods is vital for supporting overall eye health. Including a variety of leafy greens, colorful fruits, fish, nuts, and seeds can provide the necessary vitamins and minerals to promote good eyesight. It is important to note that while a healthy diet can support eye health, it does not replace regular eye exams and professional eye care.

Restoration of Eyesight and Lens Replacement at LensFactory

When it comes to restoring eyesight, advancements in medical technology have opened up new possibilities. One such treatment is cataract surgery, which involves removing the clouded lens and replacing it with an artificial lens implant. This procedure can significantly improve vision and restore clarity, allowing individuals to regain their independence and enjoy a better quality of life.

In addition to cataract surgery, the use of advanced technologies has revolutionized vision correction. Innovative procedures like LASIK and PRK reshape the cornea to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. These procedures offer precise and long-lasting results, providing individuals with clearer vision without the need for glasses or contact lenses.

LensFactory plays a significant role in helping individuals upgrade their vision through lens replacement services. This convenient solution allows individuals to replace their lenses while keeping their favorite frames intact. The process is hassle-free, offering customization options to cater to specific prescriptions and lens preferences.

LensFactory's lens replacement services are a reliable and cost-effective solution for individuals seeking to upgrade their vision and enhance their visual experience. With convenience, customization, and top-quality lenses, LensFactory makes it easier than ever to restore and improve eyesight without compromising personal style.

Aging and Vision Changes

As we age, our eyes undergo natural changes that can impact vision. Two common age-related changes are presbyopia and reduced visual acuity. Presbyopia is the gradual loss of the eye's ability to focus on nearby objects, making it difficult to read or perform close-up tasks. Reduced visual acuity refers to a decline in overall sharpness and clarity of vision.

Regular eye exams become increasingly important for seniors to monitor these age-related changes and detect any underlying eye conditions. Eye exams allow optometrists to assess visual acuity, screen for eye diseases like glaucoma and cataracts, and prescribe appropriate vision correction methods. Early detection of any issues can lead to timely interventions and improved quality of life.

One misconception surrounding age-related vision changes is that they are unavoidable and untreatable. While it's true that these changes are a natural part of the aging process, there are effective ways to manage them. Prescription eyeglasses or contact lenses can compensate for presbyopia, enabling seniors to read and perform close-up tasks with ease. For reduced visual acuity, corrective lenses or refractive surgeries like LASIK may be recommended to enhance distance vision.

Proactive eye care is vital for seniors to maintain good vision health. It involves not only regular eye exams but also adopting healthy habits and lifestyle choices. Protecting the eyes from harmful UV rays by wearing sunglasses and using adequate eye protection in certain environments is crucial. Eating a nutritious diet rich in vitamins and antioxidants can also support eye health. Additionally, managing systemic conditions like diabetes and hypertension, which can affect vision, is important in preserving eye function.

By emphasizing the benefits of proactive eye care, such as maintaining independence, preventing accidents, and enjoying a higher quality of life, seniors can be encouraged to prioritize their vision health. Age-related changes in vision shouldn't be seen as an inevitable decline, but rather as a manageable aspect of aging that can be addressed with the help of regular eye exams, appropriate vision correction methods, and healthy lifestyle choices.

Conclusions, and Next Steps

Understanding the causes and remedies for bad eyesight is essential for maintaining optimal vision health. While bad eyesight can result from various causes such as refractive errors, genetics, age-related changes, and eye diseases, there are solutions available to address these issues.

Corrective measures like glasses, contact lenses, refractive surgery, and lens replacement services offered by LensFactory can effectively improve vision. LensFactory provides a convenient solution for individuals looking to replace their lenses while retaining their preferred frames.

Regular eye exams play a crucial role in detecting early signs of bad eyesight and managing existing conditions. It is important to address blurry vision promptly by seeking professional eye care to determine the underlying cause and appropriate treatment options.

While genetics can contribute to bad eyesight, lifestyle factors, such as excessive screen time, can also impact vision. Practicing healthy screen habits, taking breaks, and protecting against blue light exposure can help mitigate potential eye strain and discomfort.

Maintaining a balanced diet rich in essential vitamins and minerals is beneficial for overall eye health. Certain nutrients, including vitamins A, C, E, zinc, and omega-3 fatty acids, are known to support good vision. Incorporating foods like leafy greens, carrots, citrus fruits, fish, and nuts into your diet can promote healthy eyesight.

It is important to note that while some vision conditions may not be completely reversible, advancements in medical technology have made it possible to restore eyesight through treatments like cataract surgery and innovative vision correction procedures.

LensFactory offers lens replacement services as a convenient and cost-effective alternative to purchasing new glasses. With a wide range of high-quality lenses and customization options, LensFactory allows individuals to upgrade their vision while keeping their preferred frames.

In conclusion, bad eyesight can be caused by various factors, but there are remedies available to address and improve vision. Regular eye exams, proper vision correction methods, healthy screen habits, a nutritious diet, and lens replacement services from LensFactory can help individuals maintain optimal vision health and enhance their overall quality of life.

ONE LAST THING!

April Fools!  We love playing pranks!

Please accept our sincerest apologies 😅

Whether you love the outdoors or prefer indoors activities, there are distinct types of lenses that will improve your experience.

Why is selecting the right lenses so important?

A good mechanic will tell you the job is much easier with the right kind of tool.

It's much the same with glasses. If you pick the right lenses with the right enhancements, the activity you are doing will be easier and more satisfying.

There are polarized lenses that block glare.

There are photochromic lenses that darken with increased sunlight.

Tints that improve contrast or improve color variation in landscapes.

Blu-Blockers that, you guessed it, block blue light.

And anti-glare coatings that allow more light to enter, which helps block glare.

The correct lens upgrades to plastic, polycarbonate, or glass lenses add to the wearers positive experience.

Glasses for Fishing

While you're fishing, does the glare from the water's surface make it difficult to see below the surface? Does it make your eyes hurt?

Polycarbonate and Trivex are both recommended lenses because they are lightweight and impact-resistant.

Polycarbonate is thinner and lighter, but less resistant to scratches.

That said, many anglers prefer glass lenses due to their scratch resistance.

Glass is also the clearest material. It is heavier, but to many wearers, the scratch resistance wins out and they choose glass if the prescription is low.

There are different treatments and lenses to consider depending on whether you fish in shallow water or deep water:

Off-shore Fishing

Off-shore fishing is when you are fishing at least thirty meters deep, and fishing is done in direct sunlight. The glare and sunlight bouncing off the water is intense, which makes it hard to track the fish.

An excellent choice for lenses is a gray polarized lens with a blue mirror. These enhancements will not only allow to see the fish under the water, but also block the glare that hurts your eyes.

Shallow Water Fishing (Lake and River)

Shallow water fishing is for water less than 30 meters deep. The focus in this situation is to optimize contrast, so of course polarized lenses make sense. All fishing lenses should be a polarized lens.

The polarized lenses should have a copper base color and a green mirror. This will improve contrast in the darker water.

Best prescription glasses for hunters or shooters

Besides your prescription glasses giving you the ability to see better, a shooter or hunter in the outdoors would appreciate being able to see brighter and with optimal contrast.

If you shoot target practice or skeet, yellow or rose lenses will make targets brighter with more contrast.

If you are an avid hunter, then polarized lenses are an option as well as Photochromic lenses and a non-nlare coating will improve contrast and reduce glare.

Eyeglass considerations for golfers

Is it hard to see your ball in certain light conditions? Or is it hard to see your ball in the sky to know where it is going?

The right pair of glasses can improve the contrast between your golf ball and the sky, as well as other backgrounds on the golf course.

A contrast enhancement (e.g. rose tint) and a mirror coating are necessary, because these features enhance depth perception and clarity.

Polarized lenses on the other hand are not a good option for golfers. Polarized lenses play havoc with depth perception, which is not so great on a golf course.

Do you like to play in the snow?

Besides goggles when you are active, your dress glasses can help you navigate a snowy holiday. Glare from sunlight reflecting off the snow can be blinding. You can choose lenses that will block this glare.

Polarized lenses are an excellent choice, or look for transitions lenses, which change with the environment and conditions. Pair that with a non-glare coating and you'll never wince again!

Are you a cyclist?

Cyclists should select lenses that are scratch resistant and lightweight to ensure durability. Avoid polarized lenses, because polarization throws off depth perception.

Instead focus on contrast – enhancing colors. Consider a rose or copper tinted lens and, of course, a non-glare coating.

Are you a boater and sailor?

Polarized lenses are what you want to have when you are on the water, period!

These lenses protect your eyes from painful glare and allow you to see through the surface glare of the water. That means you can see any obstacles underneath the surface of the water.

Polarized lenses come in assorted colors. A rose or green tint is a good choice.

Are you a runner?

If running is your jam, try a polycarbonate lens. They are lightweight and impact resistant. You can choose a lens color that will improve your eye comfort, improve contrast relative on your terrain, and allow you to see all the bright colors.

The goal is to choose a lens color that will offer the best contrast.

High contrast lenses boost depth and color perception, and they will help you read the terrain. The best tint to choose is a rose-copper.

Stay away from gray tints, because they will tend to block color variations and make everything look gray.

Are you a gamer or do you spend hours at work on your computer?

If you wear prescription lenses and spend hours on a computer each day, get glasses with blu-blocker, along with an easy to clean non-glare coating on your lenses.

Digital screens have a negative effect on the health of our eyes, often making them hurt after being on the computer for a couple of hours.

Blue light, which comes from device screens, can suppress melatonin production, which causes sleep disruption. Lenses that block blue light can give you a more consistent sleep schedule. 

A non-glare coating on the lenses will generally reduce the glare from your computer or phone screen.

That number is even higher when you include children under 18.

Still, only 12-15% of consumers choose to purchase their eyewear online.

Shopping online, it can be difficult to know what frames will fit and look great on you.

Will the company get your prescription correct?

What if something gets lost in the mail and you're without glasses?

Eyewear is a big investment and buying online can come with uncertainty. Below are lots of questions answered to hopefully make you feel more confident ordering prescription lenses online.

Why replace your eyeglass lenses?

• Your lenses scratched, cracked, or broken
• Normal wear and tear (most common reason)
• Vision needs change – a new prescription

Often, the frames have simply outlived the lenses. If you're looking for replacement lenses, these are common reasons you may go the online lens replacement route:

• Their favorite frames have been discontinued or unavailable
• Preference to antique or vintage frames, but need a modern lens
• Your frames fit you – you like them, and don’t want to change
• An affordable alternative to buying new glasses
• You have and keep multiple pairs and styles to choose from.

Can you replace eyeglass lenses in any frame?

In general, you can replace lenses in any frame.

By upgrading your lenses, you’re upgrading your vision and hopefully seeing better than before, without changing your look.

We have a few exceptions in our FAQs page, and you're always welcome to contact us with questions before ordering.

Can you replace lenses for a strong eyeglass prescription?

Absolutely, you can!

High Index Lenses are usually the way to go.

With our US-based lab, we can handle the strongest of prescriptions and help guide you to the right choice, so you don't have that “glass bottle” look in your glasses.

Offering just about any prescription need from plano (no prescription) to prisms, we can take care of it.

Can you replace lenses for any type of prescription?

You can!

In fact, we have a wide selection of lenses available by vision need and prescription specifics.

• Single Vision Lenses
• Bifocal Lenses
• Trifocal Lenses
• Progressive Lenses
• High Index Lenses
• Custom needs such as prisms and we're skilled at managing strong prescriptions

What materials do replacement lenses come in?

• Plastic - most affordable, very clear view
• Polycarbonate - shatterproof, thin, most popular today
• Glass - highest clarity, naturally scratch resistant
• High-Index - thinner material available for strong prescriptions

What lens options are available with replacement lenses?

• Anti-scratch & UV coatings should be standard on all lenses
• Anti-reflective lenses
• Blue light blocking lenses
• Photochromic/Transitions lenses
• Polarized lenses
• Tinted lenses

How can eyeglass tint color benefit me?

Did you know that tinted or colored lenses aren't just for looks?

Certain tints can benefit your daily life, depending on your job or the hobbies you take part in.

Some people with dyslexia even report fewer problems with tinted lenses.

• Yellow/Orange: Enhance contrast in low-light conditions, such as night driving
• Brown: Reduce eye strain for those with near-sightedness in bright light
• Gray: Reduce fatigue and make good all-purpose sunglasses
• Blue/Purple: Enhance vision in foggy weather and protect against highly reflective surfaces
• Pink/Rose: Enhance depth perception and detail, may reduce migraines

Can you replace polarized or Transitions eyeglass lenses?

Yes, you can replace your polarized or Transitions lenses. Even if you don’t have polarized or transitions lenses today, you can replace your lenses with them.

What are polarized lenses?

Polarized lenses scatter light rays to reduce the intensity of sunlight and reflections. Additional benefits include UV protection, reduces glare, reduced reflection, and less eyestrain.

What are Transitions lenses?

Transitions lenses (photochromic lenses) combine one pair of glasses for indoor and outdoor use. They are clear lenses that darken when exposed to UV rays.

Transitions lenses are also available as polarized Transitions lenses.

How long does it take to replace eyeglass lenses?

From the time we get your frames, most lens replacements are completed and back to you within 3-5 business days.

The simpler your selections and prescription are, the quicker they go out.

Generally there are 1-3 days on the front and back of the replacement process for shipping, which can make the total processing time as little as 5 days.

Plastic lenses without any coatings are very quick. They can usually be in and out of our labs within 1-2 days.

On the other hand, glass lenses with anti-reflective coating can take up to a few weeks.

If you’re unsure about how long it will take, just ask us!

Is replacing lenses the right choice for me?

At the end of the day, deciding to choose replacement lenses over purchasing a new set of frames and lenses comes down to a question of need, willingness to try a new method, financial situation, and other factors.

Are your frames broken? Of course, replacement lenses cannot fix that. 

However, if you love your frames, for the most part you can keep them and just replace the lenses.

We’ve shown that no matter your vision needs, your frame type, your material or coatings, LensFactory has you covered.

Check out our full infographic about replacement lenses!

Generally, that means you’re focusing on the brand, color, and shape of the frame.

While having great frames is important, it's the lenses that protect your eyes and correct vision problems.

Vision problems range from person to person, but the main refractive problems are nearsightedness, farsightedness, astigmatism, and presbyopia.

These problems can often be minimized or resolved with the proper lens upgrades.

What are common lens upgrades for glasses?

A few common lens upgrades we offer at LensFactory are anti-reflective coating, anti-fog coating, photochromic lenses, blue light lenses, and tinted lenses.

These lens upgrades offer all sorts of benefits, like reduced glare and reflections, protection from UV rays and blue light, minimizing foggy lenses, and let's be honest - some of them look just plain awesome (especially on you!).

All of these upgrades point back to the most important thing: keeping your eyes healthy and your vision clear.

Anti-reflective Coating for Glasses

The most common lens feature prescribed by your doctor will be anti-reflective coating, often abbreviated AR.

Anti-reflective coating blocks reflections and glare from overhead lights or camera flashes, so that other people can see your eyes. This lens upgrade also assists with nighttime driving because it blocks headlight glare from oncoming traffic and streetlights.

What is anti-reflective coating?

Anti-reflective coating, sometimes called anti-glare coating, is a lens coating designed to decrease or eliminate the amount of light that is reflected from your lenses.

The coating can be applied to the back, front, or both sides of your lenses to help reduce the amount of glare or mirror effect you get when looking into your lenses.

About 4% of light will be refracted at each surface of an uncoated lens. When anti-reflective coating is applied, it reduces the refraction to less than .1%.

So, instead of only 91% of the light that enters your lenses reaching your retina, 99.9% reaches your retina.

In plain language, you will definitely see better with anti-reflective coating on your lenses.

How is anti-reflective coating applied?

Anti-reflective coating is a layered combination of metals or oxides. These metals and oxides are put into a vacuum deposition coating machine in a powder form.

As the materials and lenses rise in temperature, the oxide powder coats the lenses in a specific order, depending on the type of coating being applied.

If you’re interested in how glasses are made, check out this cool video of our lab, one of the largest in the industry.

Fun fact: our lab manufactures approximately 6,000+ pairs of eyeglasses per day. Safe to say we know what we're doing!

Do I need anti-reflective coating?

Anti-reflective coatings will help you see better, without a doubt.

Upgrading will also enhance the clarity of your lenses and virtually eliminate the reflections that you and others would otherwise see in your lenses.

Anti-reflection coating reduces eye strain by allowing virtually 100% of available light to reach your eyes.

Are there different types of AR?

Yes! Like just about anything, there are name brands of AR coating available.

Here at LensFactory, we offer our house brand of anti-reflective coating, which was designed and formulated in-house to be a great alternative at less than half the cost of a name brand.

Is anti-reflective coating expensive?

Adding any feature to your lenses will increase the cost, that's a given. After all, there is more work and material going into your custom lenses.

Here at LensFacotry, we offer complete lens replacement for less than half the cost of purchasing through a retail store.

So, an upgrade for anti-reflective coating, for something you use daily and that helps you have clearer vision, is worth a nominal fee in our view.

To us and to most of our customers, anti-reflecting coating isn't too expensive. Anti-reflective is the most popular lens upgrade at LensFactory, with roughly 65% of our orders containing it.

Anti-Fog Coating for Glasses

Tired of having your glasses fog up every time you get out of your cold car on a hot summer day?

How about when you’re wearing a mask and your glasses must be cleaned after a few minutes after putting them on?

Our proprietary anti-fog treatment will keep your glasses free of fog!

We recommend anti-fog coating for medical professionals and other people required to wear a mask all day long.

Anti-fog coating is a treatment applied to the back of the lens, and you do not polish the back of the lens when cleaning them.

Photochromic Lenses

Photochromic lenses offer an all-in-one prescription eyeglasses and sunglasses solution.

These special lenses are manufactured with a mix of chemicals that react to ultraviolet (UV) rays.

The UV rays cause the lenses to darken into sunglasses when outside and exposed to sunshine. When the UV light is removed the lenses return to regular indoor eyeglasses.

Photochromic lenses do not respond to visible light - only to UV light. So, if you are outdoors or in your car and not exposed to UV light, they will not darken.

Most notably, photochromic lenses contain blue light filter, which helps protect your eyes from the glare from computer screens.

Photochromic lenses have different degrees of darkness when exposed to sunlight.

We offer two types of photochromic lens upgrade:

1) Our house brand, for light sensitive people who just want to shade their eyes in sunlight.

2) Transition© brand, which darkens to be more like sunglasses.

Both of these options are available when you're viewing lenses here on our website.

Are photochromic lenses expensive?

Even though photochromic lenses cost more than clear lenses, they can be quite cost effective.

With photochromic lenses, you end up not having to buy two pairs of glasses: prescription sunglasses and normal glasses. You get the best of both, rolled into one simple solution.

That extra convenience is worth the cost!

Are photochromic lenses sunglasses?

Like we mentioned, our in-house brand works great for people who want to shade their eyes in sunlight, but don’t want a really dark lens.

Conversely, we also offer the Transition© XTRActive lenses. These provide a much darker lens in sunlight and are intended to act as sunglasses.

They filter out a good deal of the harmful UV rays emitted from the sun, leading to healthier and happier eyes. And as an added benefit, these also have blue filter built-in to protect your eyes from the computer and other LED screens.

What options are available for photochromic lenses?

Transitional lenses come in a myriad of styles, shades, and tints that should be suitable for anyone’s taste and fashion.

We offer three iconic lens colors – gray, brown and graphite green (G15).

If you are looking for better contrast to increase visual acuity for things like golfing and fishing, then photochromic brown is the color for you.

And if you are looking for the absolute darkest transition lens possible, you should veer towards Transition© Xtractive in gray.

Do photochromic lenses work in cars?

The traditional photochromic lenses we sell are designed to change color when exposed to UV light.

The windshield in your car has UV protection, so very little sunlight will reach the lens. So, our main options described above probably won't change much in your car.

That said, there are brands offered at a much higher price point that are particularly designed to change in your car. We're glad to help point you in the right direction. Please reach out to support@lensfactory.com for more information.

Do photochromic lenses work in cold weather?

Photochromic lenses are affected by colder weather, meaning they take a bit longer to react to UV rays in the winter time.

You may find your lens are slower to react the colder it gets.

Blue Light Lenses for Glasses

What are blue light blocker lenses?

Sunlight is made of red. orange, yellow, green, blue, indigo, and violet light. When all these colors are combined, they come together and become the white light that we see. Different colors of light impact the eyes in different ways.

Parts of the light spectrum of wavelengths are UV (ultraviolet) light and blue light.

UV light spans from 10nm to 400nm and has been found to cause aging to our skin when exposed for long periods of time.

A slightly longer light wavelength is called blue light, which spans from 450 to 490 nm. This is believed to cause different, yet similar damage to the eye as UV rays.

Risks of Blue Light

Blue light is good for you during daylight hours, because it boosts your attention and reaction times. Unfortunately, it has the opposite affect at night when you want to try to sleep and relax.

With all the computers, cell phones, tablets and televisions increasing our exposure to blue light in the evenings, what you are viewing can create problems for the body’s circadian rhythm (biological clock).

This can have a negative impact on sleep patterns and rest. Research shows not sleeping well or getting enough sleep can contribute to cancer, diabetes, heart disease and obesity.

It's important to note that blue light penetrates all the way to the retina of the eye. Research shows that too much exposure to blue light, especially from LED lights, can damage light-sensitive cells in the retina.

This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss. This is a serious problem with LED lights.

How To Protect Yourself from Blue Light

As addicting as our screen time can be these days, there's only one great solution to protecting yourself from the risks of blue light: reduce the time you spend looking at bright screens 2-3 hours before bed.

Also, if you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.

Wearing lenses that block blue light will allow other colors of light through, but specifically block blue light.

You can also reduce eye fatigue by taking frequent breaks while on your computer, smartphone, and iPad to allow your eyes to rest.

Tinted Lenses for Glasses

Lens tints serve a variety of important purposes. As we just pointed out, a well-tinted lens protects your eyes against UV radiation.

Tinted lenses can also give you a high-contrast vision experience even in bright or diffused light.

Sunlight tends to distort contrast and daylight hours have a high percentage of blue scattered light that overpowers all other colors. This leads to a low-contrast vision.

Tinted lenses can filter the blue light radiation down to the optimum level, meaning objects appear with high contrast, and colors and details appear natural.

Purpose of Tinted Lenses

Tints filter light in different ways, and some tints do a better job at blocking light than others. Some tints can actually enhance colors, while others distort them.

Tints have the ability to enhance vision in certain situations. Although you may admire a certain tint color, it may not be the best one for your lifestyle.

How does tint on glasses affect vision?

The color of the tint used on your lenses isn't simply a matter of style. Certain lifestyles and types of glasses, such as sport prescription glasses, call for particular upgrades and tints.

Tinting blocks visible light while enhancing certain colors and can improve perceptions of contrast and depth.

The most important question to ask when choosing a lens tint for both sports and casual wear are: when, where, and how are you going to use the eyewear?

What tints are available for prescription glasses?

At LensFactory, we offer a variety of tint colors in a variety of shades.

• Tint #1 is a light tint
• Tint #2 is a medium tint
• Tint #3 is the darkest tint we can make

Tint responds differently to material and coatings. Plastic will take a tint darker than a polycarbonate material, for example.

Most prescription tinted lenses are specified both by their color and a number that indicates the approximate luminous transmittance of the lens.

Light tints, #1 tints, have transmittance values of about 75% to 85% and are used as fashion tints.

Medium, or #2 tints, have transmittances of about 50%.

Dark tints, #3 tints, are commonly prescribed as sunglasses and have transmittances of approximately 20%.

We also offer a G-15 tint. This is a green tint that was developed by the RayBan company as their signature tint.

Slight blue tints on your prescription lenses can reduce glare from monitors and screens, making them ideal for office workers and people who use screens a lot.

Brighter tints, like yellows and light browns are very cool. Not only do they look great, but they also provide UV protection and superior clarity. These tints can also be very effective at filtering out blue light from electronic devices.

Rose tinted sunglasses, or pink tint, aren’t just a nostalgic way to see the world. They help to reduce blue light, which improves contrast by offering maximum glare and light protection. The high contrast makes them very soothing to the eyes and allows you to see details better, as well as visual depth. This makes rose tints ideal for lazy summer driving.

Dark tints, like green or grey tinted sunglasses, are ideal for when you’re out and about in the summer sun. Dark tints mute brightness, but maintain clarity and strong contrasts. They are dark enough to provide protection from glare but are still light enough to ensure that your vision is not impaired.

Are tinted glasses bad for your eyes?

Tinted lenses that are too dark may pose a risk for healthy individuals when worn regularly indoors. Your eyes will begin to adapt to the darker view, which makes light exposure in the future feel brighter and sometimes painful.

By doing this over a long period of time, your eyes can become more sensitive to light.

Benefits of Yellow or Orange Tinted Lenses

Yellow tints are said to be helpful for moderate to low-level lighting conditions. Surroundings may look brighter. Their contrast-enhancing property makes yellow glasses great for night driving or sports. That said, there may be some color distortion.

Benefits of Brown Tinted Lenses

Brown lenses are sometimes recommended for people with near-sightedness, or myopia. They may bring comfort to your eyes in sunny conditions or help you better see contrast.

Benefits of Gray Tinted Lenses

For those with hyperopia (far-sightedness), a gray tint may be beneficial. Gray lenses may also help your eyes deal with fatigue.

Gray lenses also make good all-purpose sunglasses. However, if you are wearing base lenses that don’t block UV light, you will find that the gray tint will allow the pupils to open more, letting more UV light shine on the retina.

Benefits of Blue or Purple Tinted Lenses

Said to enhance color perception, blue or purple lenses might be worn indoors or outdoors. They offer some protection from highly reflective surfaces, like water, glass, or snow. Blue lenses are said to be beneficial in foggy weather as well.

Benefits of Green Tinted Lenses

If you’re going out to play golf or tennis in the sunshine, green lenses may help reduce eye strain by filtering the blue and UV rays.

Benefits of Pink Tinted Lenses

Rose-colored or pink tinted glasses can improve visibility for driving, depth perception and detail. Some precision-tinted migraine glasses have a rosy color to them.

But not just any rosy coating will do — migraine glasses are specifically designed to filter certain wavelengths of light (e.g. light from fluorescent fixtures) that often trigger migraines.

You find yourself with an outdated vision prescription and want to renew it.

But then it’s the whole “look up your doctor, schedule an appointment, find time away from work and life” thing that gets in the way.

Thanks to our partnership with Visibly, you can say goodbye to that experience.

Renew Your Glasses Prescription Online

Visibly's online vision test is the first eye care telehealth technology that connects consumers with licensed eye care professionals.

This new tech allows for vision tests without the need for in-person appointments.

All you need is your computer, a smartphone, and about 6 feet of space behind you for checking your distance vision.

Note: the online exam is valid only for prescription renewals. The technology hasn’t yet advanced to provide an initial vision test – but we’re getting there!

How do online vision exams work?

With our online vision test, you can renew your vision prescription in 10 minutes or less from the comfort of your own home.

You'll receive an updated vision prescription from a licensed doctor in less than 24 hours directly to your email.

Basically, we’ve taken the traditional phoropter (the big machine your eye doctor uses to check your eyes) and digitized it.

The phoropter is one of the most basic tools used by your doctor to measure the refractive errors of your vision and determine your prescription needs.

Virtual visual assessments can make a huge difference in the quality of life for those who wear glasses and contacts.

Particularly when they’re unable to make it into an exam room.

Benefits of Checking Your Vision Online

Just like online lens replacement, checking your vision online screams convenience, savings, and accessibility.

Online vision exam technology simplifies the vision prescription renewal process for optometrists, ophthalmologists, and patients alike.

In just a few steps, you’re off to renewing your prescription the easy way.

1) Save time, money, and hassle.

While there is a $25 cost to access our online eye exam, that's a deal compared to what it may cost you to normally see an eye doctor.

Plus, you save tons of time by not having to schedule an appointment and go to your office visit.

Our virtual eye exam takes ten minutes or less. In less than 24 hours, you'll be emailed an updated vision prescription from a licensed doctor.

Lastly, taking an at-home eye exam is hassle-free and contact-free. The ability to take the exam virtually means even people in some areas where eye care professionals may be more difficult gain access to easily renew their prescriptions.

2) Reduce the burden on our healthcare system.

Online healthcare innovations, including online vision tests, are not only helpful and convenient for patients.

They can also prevent our healthcare system from becoming overburdened.

Our online exam takes no more than ten minutes to complete. 

And of course, patients who may otherwise be unable to make an in-person appointment can easily mark a vision test off their to-do lists.

3) Convenience leads to reduced prescription lapses.

The convenience and accessibility of at-home eye exams greatly reduces prescription lapses. Meaning, generally, long-term outcomes in eye healthcare improve and more individuals are safe.

Why is it necessary to get regular eye exams?

Keeping your vision prescription up-to-date is a key factor in reducing eye strain. Especially in a world where many of us spend hours each day focusing our vision on screens.

Whether you wear contact lenses or glasses, it’s important to renew your vision prescription on time every year, so you can keep seeing clearly.

Vision health is extremely important, and an updated prescription will prevent eye strain and screen fatigue.

Dr. Christopher O’Brien, an Ophthalmologist within Visibly’s Optimized Eye Care doctor’s network, recommends having your eyes checked annually, even if you are not noticing any changes in your sight.

“Maintaining a high level of eye health not only protects your eyes, but also your body as a whole."

>> Experiencing eye strain? Reduce it with these tips from Visibly.

Dr. Karen Dorman, OD also stresses the importance of keeping your vision prescription up-to-date in order to maintain your eye health and performance.

It is important to renew your vision prescription, as recommended by your eye doctor, so that you can continue seeing properly.

Common Questions About At-home Eye Exams

Are at-home eye exams reliable?

When done correctly, an at-home eye exam can accurately measure your vision and provide a prescription for renewing your glasses or contact lenses.

Remember, at-home eye exams are only valid for renewing a prescription, not for an initial vision assessment.

Are at-home eye exams a replacement for your eye doctor?

At-home eye exams can be helpful in many situations. But, no, they don’t replace the need for your eye care professional.

Taking a vision test at home won’t check the health of your eyes for symptoms of cataracts, glaucoma or macular degeneration, as examples.

If you’re having trouble seeing with your current prescription, you should see an eye doctor in-person and then consider if online renewals are practical.

Who is most eligible for an online eye exam?

Online eye exams are generally great for people who:

1. Are 18-55 years of age
2. Don’t have a strong prescription (+/-6 or more)
3. Have an existing prescription available
4. Have no risks for eye disease, such as existing cataracts, glaucoma, diabetes, or high blood pressure.

How much do online vision tests cost?

Online eye exams, unfortunately, are not free of charge. The nominal fee to renew your prescription online here at LensFactory is $25. That's a bargain considering you'll get a licensed doctor to review your prescription online!

We're also happy to share that we do not mark up the service.

Once you’ve taken the test, you'll only pay if we’re able to renew your prescription.

If your RX seems to have changed since your last visit to your doctor, you won’t be charged.

We will let you know that it may be time for an in-person visit to the optical shop.

Just remember – you don’t have to buy new glasses to get a new prescription. Simply come back to LensFactory with your updated prescription and we will replace your lenses -- you keep the frames.

Will health insurance cover an online eye exam?

Generally, health insurance will not cover this expense. However, we will provide you a receipt at the end of your service.

You can submit the receipt to them to verify eligibility. Check your individual plan to see what’s covered for you.

What states allow online eye exams?

As of this post, only 37 states were allowing the use of online vision testing technology, but this number is growing.

Online vision testing services for prescription renewal are allowed in AK, CA, CO, CT, FL, HI, IA, IL, KS, KY, MA, ME, MN, MO, MS, MT, NC, ND, NE, NH, NV, NY, OH, OK, OR, PA, RI, SD, TN, TX, UT, VA, VT, WA, WI and WY.

Some states are trying to ban this service from being accessible to consumers. Optometrists and optometry manufacturers have lobbied Congress in a claim to protect their market share.

We believe whatever the solution, it should be easy for customers.

While the test isn’t a fit for everyone, it’s a start to disrupting an industry that has lacked innovation for decades.

And we're good to stand behind innovation at all turns.

That is why on Veteran's Day LensFactory salutes both the FS9 and the MS9 along with all of those that were forced to wear a pair during basic training.

LensFactory is a Service Disabled Veteran Owned Small Business (SDVOSB).  We support our veterans and honor the all of the sacrifices made at home and abroad by the families and loved ones of our service members.

LensFactory re-lenses your existing eyewear allowing you to continue using that frame you love so much!

One of the most common questions we are asked is, why are your prices so much less than my doctor’s prices?  The easy answer is, we are a business that is a branch of an optical lab that makes lenses.  That’s right!  We are a lab located in Louisville KY that has been in business for 30 plus years. 

LensFactory is one of several e-commerce stores that is owned and operated by the lab.  This allows us to keep our prices low and pass the savings on to our customers.

The second most common question we are asked is, When I am at the eye doctor, after my exam they have me sit in front of someone and they are measuring things, how do you know what measurements to use if I order online?   

That someone is known as an optician.  An optician is someone who specializes in fitting glasses and making lens.  We have over 100 opticians employed here at our lab and can call on them at any time for their expertise and advice.  An optician can provide all the measurements we need to re-lens your frame.

If you are ordering online there's one measurement is critical to making your lenses, your pupil distance.  It is the distance between your two pupils measured in millimeters and requires a precise measurement. 

This number gives the lab what is known as the optical center of the lens. The optical center is the best and clearest vision point on your lens, and you need your pupils to line up directly with that focal point on the lens.  Once you are an adult this number will not change, so once you know your pupil distance, record it in your medical records for your future use. 

If your pupil distance is not correct it will create eye strain and headaches and make wearing your glasses unbearable, it needs to be correct.  We do not know if your eye doctor will provide it to you on your prescription.  We recommend you ask your eye doctor to provide your pupil distance to you.  

If your eye doctor will not provide it to you, find a new doctor!  There are other ways you can make the determination yourself.  There are many phone applications that you can download, and they will measure it for you.  We’ve experimented with the most popular ones and found them to be fairly accurate. 

You and a friend can also work together to measure it yourself.  Make sure you measure in millimeters and that you measure enough times so that you confirm the same measurement at least three times. 

If you are sending us a frame that has an existing prescription in it that has worked well for you, please send a note with the order asking us to measure the pupil distance from the existing lens and we will do that for you.

If you wear a multifocal lenses such as progressive, bifocal, or trifocal there is another measurement we use based on the size of frame you have.  That measurement is called a segment height.  The segment height is where the near vision stops, and the other visions begin in the lens. This line varies and is unique to each frame and individual. 

We recommend you have each frame you are sending us to re-lens measured by an optician to determine your best segment height and that you provide those numbers for us to use as well, but it is not required unlike the pupil distance.

If the segment height is not provided to us, we will use a formula that we have found works well for most people.  Let us try it!  If it does not work well for you, give us a call, or email us to discuss it.  We will happily adjust it for you.  Also, if you are a multi-focal and you wear your glasses low on your nose, please let us know by including a note with your order! That will let us know we need to make an adjustment to our formula to compensate for it. At the end of the day our goal is to have them work well for you! 

The third most common question we are asked is what brand of lens you are going to use for my frame.  At LensFactory we want to offer a great product at a fair price.  We have discovered a way to make great lens at great prices.

We order our lens blanks from all the major manufactures of lenses. Varilux, Essilor, Hoya and Zeiss to name a few.  We offer them as a house-brand lens at a discounted price.  They offer the same superior quality that the branded lens offers, but without all the marketing jargon that raises the price.

Our flair, and what makes us stand out for the rest of the crowd is our customer service team.  If you don’t know what lens you need, please reach out to our experienced customer service team and they will be happy to help you select the right lens for your prescription, lifestyle, and your frame.  Our team is here to help you move forward and understand your lensing requirements.  Let us help!

If we make lenses for you and they are not what you expected, please contact us in the first thirty days and we are happy to work with you to determine next steps.  If for any reason you are not happy with our service in the first thirty days, you may return the lens to us for a 100% refund.

Give LensFactory a try and we believe you will be glad you did!  You can start here by searching for lenses by material, or by vision need.

Plastic

Plastic or CR39 is as close to glass in clarity that you can get.  It’s the most cost effective solution, and very easy to tint.  With plastic lenses, you will generally have thicker or heavier lenses than using Polycarbonate (“Poly”).  Plastic is easy to scratch, crack or shatter.   Plastic lenses can’t be used with drill mounted or semi-rimless frames.  Children under the age of 18 cannot be prescribed plastic lenses.

Polycarbonate (Poly) 

Polycarbonate or “poly” for short is very impact resistant.  Poly lenses are thinner, lighter and more durable than plastic lenses.  Unlike plastic, poly lenses are able to be used for drill mounted or semi-rimless frames.  With these additional pro’s in poly’s favor, there is additional cost.  While we put anti-scratch on all of our poly lenses, they can be easily scratched.  Poly does have lower clarity than it’s glass or plastic cousins.  Poly, while it can be tinted, does not take tint very well.

High Index

If you have a high prescription, High Index is the way to go.  We can get the thinnest lens with High-Index lenses.  Ever had that “soda bottle” look? Say goodbye to it with high index lenses.  Many times, people use high index lenses on vanity glasses.  High index lenses are lighter and thinner than plastic, but heavier than poly.  Because it takes a lot of work to make these lenses thinner, High Index lenses are usually the most expensive lenses.  We add anti-scratch and anti-reflective coating to all high index lenses due to the amount of reflection that can occur with high index lenses.

Glass

Glass has the highest clarity and greatest optical quality due to it’s high ABBE value.  With no coatings it is very scratch resistant.  Glass is very heavy.  If you’re not used to it, it may not be for you.  Glass is NOT impact resistant and can chip or shatter when dropped.  This is not a good material if you have an active lifestyle that may put your glasses in danger of being dropped.  Glass also takes a long time to manufacture, sometimes over 30 days.

We know!  That’s a lot of information to take in.  If you'd like to read more about our lens materials, check out this page.  If you still have questions, feel free to reach out to us via phone, email or chat.  Contact Us Now!

When you get a new prescription or scratch a lens in a pair of frames that you love, you may think that your only option is to buy a completely new pair of glasses. If that's what you've thought all this time, then we're about to make your day. Let's say that you love the way that your frames fit on your face and you really want to keep them. It probably took you a long time to find them and you're not ready to change just yet. We totally understand and that's why we put together this quick guide to buying prescription lenses online, where you can save a lot of money from other traditional options.

STEP ONE - Use The Right Search Words

If you're online and search for "new glasses" you're going to find a lot of sites that want to sell you a whole new set of glasses, which means that they're selling both the lenses and frames together. This isn't helpful if you just want to replace the lenses in a pair of frames that you already own. In order to find the sites online that specialize in replacing the lenses in frames that you already own you need to search for things like, "But if replacement lenses you'll find more than likely find a site like "replacement lenses," "order lenses for glasses," or simply "LensFactory." Extra bonus points because you're already here and all we do is replace lenses in your existing frames.

STEP TWO - Order New Lenses

Once you're on a site like LensFactory.com, you will need to know a few things about your prescription. We've found that a lot of people don't necessarily know what terms like Single Vision lenses, which are lenses that only make one correction throughout the entire lens, or Progressive lenses, which are lenses that make multiple corrections in a single lens without the lines seen in traditional bifocals and trifocals. After you understand which lens type you're looking for, you can begin to pick out your new lenses material. If you've tried out different lens materials in the past, then personal preference will play a big part in your decision. Some people just prefer Trivex over Polycarbonate, for example. If you haven't tried out a lot of different materials, then think about lens materials like this:

• Plastic Lenses - The least expensive lens material and great for prescription sunglass lenses because they can hold the darkest tints.
• Polycarbonate Lenses - Great for protective eye wear because the material was designed to not shatter. Polycarbonate lenses are our best sellers.
• Trivex Lenses - Developed by the military and used a lot for protective eye wear as well as in kids glasses, due to their shatterproof design and durability.
• Glass Lenses - The original eyeglass lens, glass lenses are naturally scratch resistant, but they are also the heaviest lens type and you need to have full frames (semi or totally rimless glasses won't work with glass lenses)
• High Index Lenses - Made for very strong prescriptions that would typically need very thick, "coke bottle" style glasses. These lenses are extremely thin and light, especially in comparison to their strength.

After you've figured out your lens type and the material you want to order, you can customize them even further with upgrades like custom tints, anti-reflective coating and even make them photochromic, which just means that the lenses will automatically change their tint based on whether you're inside or outside. Check out using your credit card and you are almost done.

STEP THREE - Ship Your Glasses

You've made your order online and now it's time to send in your frames so you can get your new lenses installed. If you're sending a pair of frames that don't have your up to date prescription in them, because you got a new prescription or because these frames were either given to you or you bought them from somewhere, then sites like LensFactory are going to need a photocopy of your prescription. IMPORTANT NOTE: Make sure that your Pupil Distance or PD is included with your prescription. PD is important because it is the distance between your pupils which helps put the optimal viewing area in the right part of your new lenses. Most doctors won't write it on your prescription, but should tell it to you if you call up their office and ask.

As soon as your order comes in the door, we're checking off that we have everything and pushing your frames and new lenses through our process to get them back to you as fast as possible. All you have to do now is sit back and wait for your favorite frames to have some great new lenses in them and you're all done.

It's that easy.

We know how hard it is buying new glasses. It's tough. Do you go with the thin rectangular frames or the retro round frames? What type of face do you have and which frames go with it? The questions don't ever seem to end and the stakes are high because new frames are expensive. That's why we couldn't believe our eyes when we came across the ultimate source of "How to Buy Glasses" infographics on Pinterest. We had to share it, so here it is:

The Ultimate Source of "How to Buy Glasses" Infographics

Canadian site, jobs4ecps.ca, is winning at Pinterest with a board that will answer all of your "which kind of frames should I buy" questions in multiple languages, even. There are over 50 graphics to choose from, but the consensus seems to be that people with oval shaped faces have it made.
