what would be the advantages and disadvantages of having the glass lens?
Well, this is polycarbonate lens, not glass- just want to get that straight. With glass, you just gain clarity, but it's a clarity you cannot gain with polycarbonate. Think of telescopes, binoculars,cameras etc... These do not use polycarbonate lenses. But with polycarbonate, you have something shatterproof and leight weight. Glass is heavy and it can shatter.
