I made glasses, for a living, and all glasses are made of some type of plastic. I don't know if any "glass" are still available. The three materials that we used were, Polycarbonate, CR-7, and Hi-Index. "Poly", is used for safety glasses, because it is shatter resistant. I would also think, if it was properly coated, it would offer even more protection. To absorb the strike of an object is the purpose of a safety lens, or to some extent, all of the newer materials. I could be wrong but I think you'll find out that shooting glasses, are poly lenses, with special tinting, and side protection.
