I think glass lenses are far superior to polycarbonate in scratch resistance (except for glass lenses with fragile coatings, like Oakleys). Usually, but not always, the glass lenses will have better clarity. I've tried some of the newer polycarb sunglasses and they seem pretty close to glass in terms of clarity. The one place polycarbonate sunglasses are undoubtedly the best choice is in lenses for sports or outdoor use, because their superior impact resistance will prevent them from shattering like glass lenses do.
