Plastic is not "unbreakable." It just takes more effort to break it, My prescription glasses that I use for driving, has some cracks on edges of the lens. The plastic type that the lens are made from is polycarbonate. The only thing great about plastic is it is more pliable than glass, so a drop will not hurt it. Though abusing the plastic multiple times like dropping it multiple times will break it and also plastic is easier to have scratch marks.
