I was skeptical about these when I received them. I had never bought Smith optics before and they felt so light like cheap-o frames. However, the lenses are awesome and are so different from typical polarized lenses that make everything look dark. These actually make things look brighter, while stilll protecting your eyes. I use them for running as well as driving, and sometimes they fog a bit, but overall I'm very happy with them and would recommend.
