I've had safety rated lenses from about 1972 on. I got tired of breaking frames constantly due to dog head butts, usually in the car. He flung himself around from the day we got him until almost the end and broke many frames, usually popping the lens out of the frame by breaking it. The last time, a few years ago, I asked the optometrist to find me the strongest stainless steel frames they could. She came up with three similar looking aviator style frames, and the one I picked was from "Safilo", and they are tough, believe me. They survived a bunch of head butts from my dog, and a bunch of them from a friend's Pit Bull who loves me but hurts me almost everytime I visit his house. My nose has take a few huge shots but the glasses sail on. An interesting thing though, I still have acne (At 60!)and last summer, I had some on my temple and it bled onto the right bow and it's pitted like an old barrel from lead! I had no idea that could happen.
The only problem I've ever had shooting is when I was shooting about 10 years ago when a 9mm case somehow made it between the lens and my eyelid. That was painful beyond what I had ever imagined it could be, but that was the only bad thing that happened with "normal" glasses in 39 years of shooting.
