How strong are todays safety glass lenses?

Most safety glass lenses are today made from Polycarbonate, and this is a very tough material. The impact resistance of a Polycarbonate lens is approximately ten times higher that of a safety glass lens made from hardened glass. Both these lens types (has the potential to) meet the requirements of the Eye and Face Protection Standard, ANSI Z87.
