- When 99% of spectacle lenses are made of plastic, would you buck the trend and go with old fashioned glass? Here's why you should!

timeremember, everyone used glass lenses forever for a long time. Plastic/Poly is alll pretty new. Sports, Dr's, Drivers, Racers, etc all used glass for decades. I was hit on a bicycle with mineral glass lenses on and hit my face straight on the ground. One lens shattered. They are normally 'shatterproof' glass so they do not splinter but break into 'chunks' instead as mine did. I had no harm done. ;-) To this day I seek out Glass as nothing can compare to that clarity. Not even close. ;-)
I'm glad you agree
Yeah plastic Idc sports goggles are way better and also the NottNott reduced lens is way better and I got rid of myopia
Really cool seeing those outdoor shots in the Lake District. That Anglo American frame from the film looked cool. I guess for those with an iscription and who want the best vision possible, Zeiss glass is the way to do it! Really interesting video 👍
Yes, I still wear my glass pair from this video from time to time, usually get compliments on them even though they are such a plain, classic design
Paying a premium for a plastic lens every two years or keeping your glass for a lifetime and just changing frames. fitting and grinding glass isn't a challenge for a new styled frame or ordering new lenses for new frame keeping original as second pair . Wore glass 50 years wore plastic 6 months ! the safety of shattered glass issue isn't a issue plastic lenses cause more impairment to vision while driving with all the scratches and never getting them clean enough especially for any night driving. 1000% mark up on frames and plastic lenses for me returning to glass is a wiser investment
I should mention these Zeiss binoculars are 22 years old!
Zeiss is one of the few awesome things that came out of East Germany when the wall fell. 😎
They are from 1995, so a couple of years older. I have been using them for birdwatching since 2005. They are superb. Not sure if modern equivalents from Zeiss/Leica/Swaro have improved optics, they likely do. Never felt the need to compare, though. Or upgrade, for that matter.
Glad I found your channel 😊…. New subscriber here 👋 and new optician … I love all your contents, very helpful and informative. Thanks for all the information!
Awesome! Thank you!
The images through the binoculars are something else!
Amazing aren't they
Thanks so much for your video. I am currently looking for glass lenses, and they are getting extremely difficult to find. The opticians that do carry them tell me glass is extremely dangerous and they highly recommend against it. Is there any truth to the dangerous claim for every day wear? I could see not for sports as you mentioned but for normal use?
Frankly (after hearing what you said about i.Scription) if you were in Italy, even in the part of Italy farthest from mine, I'd have come to your shop to have my vision measured, and my eye-glasses set.
Are the DuraVision Platinum & the anti-blue-light treatment undoable on glass lenses? You didn't talk specifically of those 2.
@thespectaclefactory is hoya "my SV" about the same as Zeiss clearview/energize me? (the freeform tech for single vision)
Interesting... I'm a surgical trainee with -11 Rx. I've gone for Zeiss Individual 1.74. Might have to look at glass at some point! How does the AR coating compare?
The AR usually adheres better because the hardcoat on plastic lenses is acutally silicone dioxide (glass) which means it doesn't match perfectly to the substrate. This is why coatings on plastic lenses are more prone to delamination, especially when exposed to temperature changes as they expand at different rates.
However, a glass AR is harder to clean and more prone to fogging...
My Ray Ban aviators all have glass lenses. And I do agree that it does look and feel better than plastic lenses.
For anything else. I prefer polycarbonate.
Very few sunglasses nowadays have glass lenses - good choice.
@@thespectaclefactory Thank you, I found it weird. I don't if all Ray Ban aviators are still made with glass lenses, they just felt heavy, cold to the touch, and decided to touch them with my teeth to find out that it was glass.
I bought them all like 7 years ago.
Gotta say I didn’t expect that from Ziess lenses
Really? They are the best!
I was just told by Zeiss cust service that Zeiss stopped doing glass for eyeglasses. Is this true?
Not true.
Sir, I feel severe headache when I wear my spectacle. Prescription is of 6/6 vision.
Can my problem be solved by glass lenses.
It sounds like the prescription or lens design is the problem, rather than the lens material
I am really considering get some glasses lenses, do you think some sph glass perform better that clearview lens?
Could glass lenses work in conjunction with my clip-ons?
Would they offer better clarity and less reflections?
I find my DriveSafe work well with my clip-ons, but I do occasionally notice some reflections?
Thanks Rob👍
Yes, if all you want is the crispest, clearest vision (for example, I tend to wear mine when watching a movie, especially at the cinema) then glass is your best bet. And we can make SmartLife lenses in glass too. They would work well with an Anglo frame. You don't want to go too big due to the weight. I also have a feeling this would be a great match (and very cool): bartonperreira.com/collections/barton-perreira-x-fear-of-god2021/products/fgbp2021-50?variant=39428847534178
Hello and thanks for this very good video. I have been considering to get a glass lens for my next glasses, but i dont know what kind of coatings or technologies can be applied to a glass. I read things like umbramatic and some more, but really there is no info about what they are and uses. If its too much to answer here i would love to contact you some way. And I definitely want a zeiss lenses. Thank you.
Umbramatic means light sensitive, so gets darker when exposed to bright light. You can also get tinted glass lenses (either 20% slightly tinted or full sun) and a gold coloured coating which I think looks really premium on glass lenses.
Email me via rob@thespectaclefactory.com for more info!
Is a glass lens roughly double the weight of a plastic one? Is the prescription you talk about at the end (eyescription) what’s known as “freeform”? And does the abbe value drop with a high index glass lens at high prescription (I’m about a -6)? Thank you for the video
About 4 times the weight. The abbe value does drop, but high index glass is still optically excellent.
@@thespectaclefactory thank you! I hope u dont mind me asking questions. So many!
@@thespectaclefactory so a small frame is obviously quite important to keep the weight down for glass lens I assume
Very nice video. Which models of Zeiss lenses are made of glass?
Thanks! You have to specify, but both Zeiss Precision and Zeiss SmartLife lenses can be made in glass. We ship all over the world so would be glad to make them for you
Sony Xperia 1 Mark || is the winner of the camera business because he uses the best Zeiss lenses at the moment
Yeah, the Sony cameras take amazing photos with Zeiss lenses!
I had the same thought as I have a Sony Xperia 1iv and the pictures on a phone are unmatched this part due that it has Zeiss glass lens
Oh one more thing. Can glass lenses be made in a round/ oval shape?
Definitely!
Can we get progressives in glass?
Yeah!
@@thespectaclefactory Which brands?
Zeiss + Hoya plus a few other independent lens manufacturers
Do you think a pair of lenses can be made really really thin like a piece of paper
No only because of the safety element. The materials used in optical lenses would be too brittle to be mounted into a frame and could crack and go in your eye if they were made that thin! BUT we can make them 1-2mm thin in most prescriptions
I was thinking like could it be done really thin on some flexible materials like a form of bendable plastic. I just have an idea but wanted to know if it's even possible to cut lenses that thin.
@@williamwest5079 Well, not that I'm aware of, but you never know what the field of nano-optics is going to come out with
Do you have a private way that I can contact you , I would like to share some private information with about an idea for an invention that I have with you
Hoping no one noticed my unbuttoned shirt...
Failed 🤭
Lmao
East Asian faces, best frames ideas
7:51 IT’S NOT A COOL NEW TECHNOLOGY IT’S SO OD YOU NEED NEW GLASSES EVERY DAY IN NEWBIE GAINS AND THEY PROBABLY COST HUNDREDS OF DOLLARS
Yeah nah -0.25 is small enough. Some people even reduce by -0.5 but -0.25 is easier like NottNott said Idk it depends but -0.01 is way too small of an increment it’s literally 100 meters away
8:09 And that bus there is probably 2 meters, so -0.5. That’s literally a horrible example
