As someone who manufactured over 5 million pairs of eye glasses in my career from 1974-2013, I doubt you will find someone who can do glass. The transition to plastic started in the late 60’s then to polycarbonate in the mid80’s along with high index materials, and Trivex in the early 2000’s. The best current choices would be Trivex, high abbe value 1.60 index and for height prescriptions 1.67 index. Glass had pretty much vanished well before I retired.

With all that said, nothing matches the ABBE value and optical stability of glass. However, if you are interested, PM me your prescription and contact info, I’ll do a search for you and match it up with a local optical shop.

Do you know if OSHA approved safety glasses are still made of glass? I remember them having special impact requirements.

A google search came up with a few online companies. Here is one.

I agree

Do they do progressive, no line lenses and if so how do they know where to put the sight line? Thanks

Yes, they sell progressive lenses. I don't know how they fit them.

Hello, what is considered a decent price for progressive eyeglasses at Hindsight?

These were less than the in house eyeglasses at the opticians, and I did not have to wait 2 weeks for the glasses to be made. As I recall mine were about half the price my wife paid. Now the price is highly dependent on: the frames, the lenses and the optional coating, etc., on the lenses, so you will need to call or stop in to get an idea for your specific needs.

And lighter.

I was a master optician that learned on glass lenses. When plastic arrived in the late 60's we thought it a fad...my wife likes Clear View Optix...Mulberry

Glass on OSHA safety lenses is only special application, polycarbonate was 99.9% 10 years ago. My assumption is that Trivex may have become the material of choice, the impact resistance of poly, better optics and better resistance to chemicals.

real glass in eye glasses would be very heavy. That's why they don't use it anymore and the fact that glass could shatter and get into your eye

I have real glass, but they are getting old and would like to replace them with real glass.

I have some spares, and some recreational use pairs that are Zenni, plastic. My biggest problem with them is once they get foggy from sweat, or heat from my face, they just about impossible to quickly wipe clean and clear. And if I take the extra time to do so, they almost immediately fog right back up.
I don't have that problem with glass.

I don't have a very strong Rx, and I don't wear huge frames, so weight is not an issue.
Also, I am among the population who can discern the difference in optical quality between glass and plastic. It drives me nuts.

I have been delaying replacing my old glass pair, because of the difficulty in finding real glass. My Rx hasn't changed in many years, so I'm getting away with it, but the day is coming when I will need to buy a new pair.

For those of you who play pickleball with plastic lenses, how do keep them clear on a hot day. If I could solve that problem, I might be able to live with plastic.

As one poster said, the Walmart in Summerfield does sell glass lenses, although they told me that they are not very popular.
