I have never seen something that was scratchproof (shatterproof, whatever-proof) that lived up to it's claim 100%. I use Uvex glasses that I can change the lenses out on, personally, because it's going to happen sooner or later.

I just went to my optometrists and had them make me a pair of shooting glasses with yellow GLASS lenses.

Not as cheap as disposable plastic, you can save by buying a pair of ordinary industrial safety glasses and have them fitted with glass lenses.

I realize this doesn't answer your question, but one big problem is simply taking care of them. People that don't wear glasses (I think) have more of a tendency to abuse them. I started wearing glasses a couple years ago, and my first couple years saw me destroying several pair a year. I wasn't used to having to take care of them. After spending a lot of money on glasses and having to use scratched glasses while I was witing on another pair has mede me a lot more careful.
Shooting glasses are usually cheap, but this doesn't mean you don't need to take care of them (as you found out). You need to keep them in a case. You need to be careful about how you clean them................... Otherwise, you damage them and they are useless.

In direct response to your question, I would say that you need to get some made of actual glass instead of plastic. It is much more resistant to scraching, although you can scratch it pretty easily.

with yellow GLASS lenses

Correct me if I am wrong but doesn't glass inherently NOT MEET the ANSI spec (whatever the number it is) for safety glasses?

i.e. something hits your glass lense, it breaks and sends glass into your eye?

As in they're not safety glasses iof they are made from glass?!

i keep them in a case. A scratch always forms because as the rifle recoils, sometimes if the glasses are far enough out, the metal rear sight scratches the plastic.

That makes sense. You might be right. I don't know enough about glass to really say.

There is no such lens as scratch proof or unbreakable. The most scratch resistant is glass but it is the easiest to break. The best option is to take care of your lenses and to have a scope with a longer eye relief. Make sure that your scope is at the proper distance from your lenses so the image will fill the eyepiece in its entirety.

444, shame on you that's covered under NFPA 1500. Kidding... :D

The spec everyone was looking for is ANSI Z87.1, but I don't know if there is anything specific on glass. Most places are going to optical quality lexan if I remember correctly.

I agree with you about the glasses though. I don't wear prescription glasses, but I used to wear cheap sunglasses and couldn't figure out why they only lasted a month or so. When I bought my first expensive ones about ten years ago (Gargoyles) I learned why. I didn't take care of them.

Now I only buy quality sunglasses and they last much longer than I would expect them too. It's usually a freak accident that damages then now. I still cry every time though.

What do your think safety glasses were made from before plastic??

Safety glasses with glass lenses are made from a special tempered glass that doesn't shatter like regular glass.

These are still used these days in abrasive conditions, like machine shops where grinding and metal work is being done.

Plastic safety lenses get scratched up way too quick, so either disposable plastic glasses are used, or the glass lenses are used.

People who work in these environments who need prescription safety glasses especially need glass due to the longevity of the lenses.

As long as the glass lenses aren't deeply scratched, (which weakens the lens) these are great for people who are hard on glasses.

Again, talk to an optometrist. They fit glass safety lenses.

NFPA 1500 :uhoh:

Don't tell anybody I missed that one.

As far as the safety standards apply, Z87.1 deals with impact resistance of spectacle lenses. They apply the same to glass, plastic (CR39), polycarbonate (Lexan), and other materials such as Trivex. Lenses are either dress wear or safety. Safety lenses must meet higher impact resistance usually achieved through thicker lenses. The lenses can all be broken by enough force. Glass will break the easiest then plastic then Trivex then polycarbonate. Scratch resistance is highest with glass then plastic then Trivex then polycarbonate. With weight glass is the heaviest then plastic then trivex then polycarbonate. Last but not least is optical quality (Abbe value) with glass the highest then Trivex then plastic then polycarbonate.

Trivex is the newest material. It has excellent optics, light weight, and good impact resistance.

Another consideration is which materials can be tinted or coated.

Just a few things to confuse everyone.
