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

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

]]>Cue Endless Drive Progressive lenses, designed specifically to:
>> Driving lenses now available in our Occupational Lenses collection!
They are generally designed to offer clarity, reduced glare, and enhanced comfort, making them the ideal choice for anyone looking to optimize their vision on the road.
According to a customer survey, 97% of wearers of Endless Drive Progressive lenses responded that they felt much more comfortable driving during the day and at night.
What makes Endless Drive Progressives the best lenses for driving are expanded visual areas and targeting of night myopia.

Our driving lenses also offer a range of general benefits, like:
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:
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:
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.
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.
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:
A: Polarized lenses are often considered the best lenses for driving as they cut glare, reduce eye strain, and improve overall clarity, making it easier to see the road ahead.
A: Gray tints maintain true color perception, while yellow or amber tints enhance contrast and depth perception, especially in low-light conditions, providing optimal visibility during both day and night driving, particularly when you're searching for good glasses for night driving.
A: Glasses with UV protection, anti-glare features, and a neutral gray tint are ideal for day driving as they reduce glare, shield your eyes from harmful UV rays, and maintain true color perception.
A: Yellow or amber lenses are recommended for night driving as they enhance contrast, reduce glare from oncoming headlights, and improve depth perception, making it easier to see in low-light conditions, proving to be the best eye glasses for night driving.
A: Transition lenses darken or lighten depending on the level of UV exposure. They’re a popular choice for their convenience -- not having to switch back and forth between your everyday glasses and sunglasses.
Most cars have an anti-UV treatment on the windows. Since transition lenses require UV exposure to work, they often don’t change significantly while in a car.
So, while there is no problem wearing light-sensitive lenses while driving, you're not necessarily improving your driving visibility with Transitions lenses.
A: Anti-glare coatings and polarized lenses can help reduce glare from oncoming headlights, improving visibility and reducing eye strain during nighttime driving.
A: Yes, anti-glare glasses effectively reduce reflections and improve vision, especially during night driving, by minimizing distractions caused by glare from headlights and other light sources.
A: Anti-glare glasses with yellow or amber tinted lenses can help reduce halos and glare, improving overall night vision and making it easier to see the road ahead.
A: Polarized lenses and anti-glare coatings can help reduce the intensity of oncoming headlights, allowing for clearer vision and safer driving at night.
A: While night driving glasses can be worn during the day, they may not offer the same level of UV protection as daytime lenses. It's best to opt for lenses with UV protection and a neutral tint for daytime driving.
A: Yes, specialized night driving glasses with anti-glare features and yellow or amber tinted lenses can significantly improve night vision, reducing eye strain and enhancing overall safety.
A: Astigmatism can cause blurry vision, especially at night, making it more challenging to see clearly while driving. Prescription lenses tailored to correct astigmatism can help improve night driving and overall vision.
A: Opting for lenses with anti-glare coatings, yellow or amber tints, and proper prescription can help improve night vision while driving, reducing eye strain and enhancing safety on the road.

]]>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 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 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.
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 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!
