Sunglass lenses, especially the interchangeable ones, seem to get scratched eventually no matter what, whether they are good or cheap ones. I had some very nice Smith glasses and lenses. Three years of use and switching - and one crash- and it was time to replace them. I didn't want to spend too much so ended up ordering from Performance. Don't know if they still have these on sale, but I got the Athena glasses, made for smaller faces. They fit pretty well, not perfect, but neither do any of the more expensive ones I've tried on. They are not huge on my face, they cover the sides well enough. They come with three interchangeable lenses and they're easy to swap out. I just got them, tried them on, and wore them out once. So far, so good. I am not sure of the price - I think they were only $25. For that price, I could get new ones every year if needed. So there's my two cents, Snappy. See what others have to say and good luck!
