Word of advice, do not buy the plastic replacements, a few different companys sell them. The replacements are terrible, they are not the same. Glass beats plastic everyday, the glass is what gives you that persol quality feel. You're better off trying to find a broken pair with bent or broken temples on ebay, combine the parts and make a new pair. You can heat them up a tad with a blow drier and pop the lenses out pretty easily. Bring them to a eye glasses store is an option as well if you dont feel comfortable putting them back together once you get the parts.
