I have a ? on polycarbonate lenses. I personally, do not like them because they seem to scratch more on the backside of the lenses more than any other lens, however, since it is the safest lens available, I am supposed to recommend to everyone including children who are rough on glasses. I agree the very first important factor is saftey which would definatley be poly, but what about the scratches? Does anyone know how trivex compares to poly and should I be recommending that?
