I'm confused about the UV in poly carbonate lenses. The video states they naturally block 100% UV rays, so why does it need additional coating still? The video doesn't say whether trivex needs additional UV coating, but also says they block 100% UV light. Clarification, please!
I have the same question! If they block UV 100%, why do they need to be coated and does that coating get easily scratched. It sounds like the polycarbonate needs to be stabilized with a coating to truly block UV.
MyEyeDr sold me polycarb lens and I do not like them. Always cleaning them hoping to get a clear picture, but never satisfied. I want glass lenses - or at leave Trivex. I wish you had covered glass lenses.
She does mention that glass lenses are more scratch resistant and thinner than plastic. Some people are concerned and warn about glass lenses in the event of a car crash, as the airbags would break them, thus making them a real safety hazard.
Thanks for sharing your input, I just ordered some Wiley X glasses and was looking for something that had impact protection and the company I was ordering from had the Trivex a little cheaper than poly so I went with that option.
Thanks for the informative video but I'm curious - along with others- as to why you didn't explain the pros and cons of glass lenses? A video covering glass lenses would be very much appreciated. Thank you in advance for your thoughtful consideration!
I am fairly knowledgeable on this. Glass has Superior scratch resistance and Superior Optical quality. However, glass is significantly heavier and thicker so if you have even a moderate prescription this will be noticeable and if your lenses are large it's a no-go. Also, although glass is difficult to scratch it will chip if you drop them. Will probably chip more easily than a plastic lens. Little tiny chips. Think about it, glass is hard and brittle while plastic is soft and tough.
@@PlumbNutz Before plastic lenses became cheaper glass was always used, I had glass lenses as did everyone I knew, it was only in the late 90s that my opticians changed to plastic lenses, so I had glass lenses for over 20 years without any problems, the only broken glasses I saw were the frames, I still have my last glass pair, single vision weigh 52 grams in a metal frame, my present varifocal glasses weigh 25 grams in a metal frame
Had similar experience with glass lenses. Most of the time the frames broke but not the lenses, unless one dropped out of a loose frame onto the ground & typically chipped.
I cannot wear polycarbonate. The chromatic aberration is unbearable Trivex has slightly less, but still noticeable. Why do optical stores 'push' polycarbonate and Trivex? They must be a lot more profitable for them.
@@RXSafety maybe you do but my place didn't offer anything other than polycarbonate! This was not a Wal-Mart or lens crafters type place either, not happy.
@keithsr Have had the same experience in the past few years. Many of the optical places often only recommend polycarbonate lenses. It may also be due to some of the insurance companies they are connected with who don't want to pay for Trivex or newer materials.

I don't really agree with all this. The difference in Optical Clarity between trivex and polycarbonate is meniscule and for many people not possible to notice. Trivex is heavier than polycarbonate, not by a lot but by about the same degree trivex is more clear than polycarbonate. Polycarbonate also has a slightly higher index so the lenses will be a little bit thinner. Trivex may be a tiny bit more scratch resistant but your primary scratch resistance is from the lens coating.
A go for trivex every time... They are a good middle ground for me... but I think it depends on prescription you have... If you have a high one like really high then you'd need to go at least mid/high index.. If your perception is lower very low standard 1.5 with good coating would be fine...
Something I haven't heard much about is a scratch index. How 'HARD' are the Trivex in comparison to polycarbonate plastic? Are they Thinner OR just a higher index rating? Because those are TWO different things no??
Thank you so much for guidance, my daughter 's prescription -5 and -3 What is suitable index for her and what type of lenses is good, let me know please
Ok, here’s my problem with wearing safety glasses over my prescription glasses. They are too bulky, very uncomfortable and falloff or move. My main concern with safety glasses, is to protect my lenses from damage while working in an environment with saws, air tools and other equipment that produce flying debris. I would like to see a protective clip on lens, or a protective plastic film that can be removed after a heavy debris episode. Just like a NASCAR pit stop window clean.!!!
What will be the best glass to use for night time driving? I did Lasik surgery some years back and it severely messed up my night vision. My polycarbonate with antiglare is not so helpful. Pls help. Thanks
Hi Olisa Ndu, thank you for watching. :) The best glasses to wear for night time driving are the ones with dark yellow lenses, as they help reduce the glare of the headlights of oncoming vehicles or any other bright light coming towards your face. Please let us know if you have any additional questions.
Hi Uchiha Itachi, thank you for watching. Both are great for screen use. Plastic lenses are thinner and cheaper, while Trivex has a higher optical quality and is impact resistant. For computer gaming we recommend adding the blue blocker coating for extra protection. Please let us know if you have any other questions. :)
I got trivex lenses I’ve had trouble getting used like getting disoriented is that normal also I have a very mild prescription is trivex good for stronger prescription?
Hi Carl Oegema, thank you for watching. Trivex lenses are a higher quality optical and resistant lens material. If you are having issues with your prescription, we recommend you talk with your optician for a better evaluation. Please let us know if you have any other questions.
I've got plenty of prescription sunglasses, both glass and plastic. Recently got a polycarbonate pair with all the coatings....far superior, super clear, no fingerprints etc. Great for driving, being on the water etc...almost double the cost though, Mine were $500AUD for the lenses
Cr 39 is pretty good and cheap but it has many drawbacks.. Out of all the the glasses material it has the worst index or refraction and the heaviest... That means that your glasses will be thick and heavy. if prescription is high .... Also if High most makers don't wanna make them above a +/-2 or 3 for some reason.and they force you to go high index.. I also find the Cr 39 has more distortion on the sides.. than trivex... I think Trivex is the best because it's a good middle ground..
I'm just getting my first set of glasses that are mainly going to be used for driving and I'm an avid motorcycle rider yes transition is a must I believe I opted for either the polycarbonate or the plastic due to the lightweight what do you think I still have time to change my mind? Again, first time user of glasses your help and advice would be able lesson🛐😎 I have astigmatism and lightly farsighted please help me what you choose
Hi Highlander, thank you for watching. All these lenses are resistant to impact. The Trivex and Polycarbonate lens material is impact approved and used in safety glasses and sports. Please let us know if you have any other questions.
Hello, my name is Cosmo Frank Guarriello Jr. Im looking for big frames, glass or trivex lenses and I also want to do a eye exam., the size I'm looking for is 60-18-150. The lenses I want are glass lenses or trivex, brown transitions the latest tech, 2year warranty, super hydrophobic, scratch resistant, UV protection, blue light, anti fog, durable, anti water, anti oil, anti smudge also very important I want thick lenses not shaved down or thin, very thick is what I want. Which one do you recommend for what I want?
With a large lens they will be heavy when made from glass or trivex to a lesser degree. They will also be thick depending on your prescription. For a really large lens you should go with high index in my opinion.
Hi @YVBSV, While Trivex lenses are highly durable, dark tints can limit visibility in low-light conditions. If this is a concern, please consider exploring other tint options or contacting us for advice on the best solution for your needs.

Hi Mary, not really but if you ever want to add coatings to your lenses you can always contact us to get them redone. Or you can place a lens replacement order with us, this is the link to that service on our website: rx-safety.com/lens-replacement/
I've never needed glasses😳 & I have perfect eyesight🤩‼ But my best friend🤓 has had glasses since he was 8! I bet he knows all about these problems, whereas I😌 don't! These are his eyes👓, and these are mine 👁👁❕❗
There are people out there making glass lenses and even especially thin ones if you look around. However, it's still going to be heavier than anything plastic and most likely thicker. Optical quality of course is the best but although they are extremely scratch resistant they will chip if you drop them in a way that plastic lenses won't. Think about it, glass is hard and brittle while plastic is soft and tough.
Hi Ovidiu Turcu, thank you for watching. :) We agree that glass lenses are a great option, and for that reason RX Safety also sells eyeglasses with glass lenses. Please let us know if you have any additional questions.
