All lenses are tempered glasses, also called Toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering creates balanced internal stresses which cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards. The granular chunks are less likely to cause injury. Comparing with polycarbonate lens, it is usually heavier than the polycarbonate, but the polycarbonate is easier scratched.
