These are great glasses. Great fit, great style, great lenses....but you better not scratch them. I managed to put a small nick in one of the lenses and Kaenon wanted over $100 to replace it. Now I'm tough on my stuff and don't mind paying to fix something I've managed to damage, but $100+ for a lens is ridiculous. If you plan on being active while wearing these, I'd get something else.
