Rudy Project rocks! I've already raved about these in another forum. They aren't cheap, but are relatively impervious to scratches and come with a bomber hard case to store and trasport them in. They will replace scratched lenses no questions asked. I have Skeeys, which are a bit goofy on my small face, but they have come out with smaller models (most with the suffix "SX" as in "Rydon SX") in the years since I got mine. Yes, I have had the same pair for years and have not had to replace the lenses, and I am not the most careful gal around. They have a lot of lens options. I have a very narrow bridge nose, can't wear most plastic frames, and the Skeeys are one of the few glasses that have an adjustable bridge.
