"Nice Specs" - Review of Smith Factor Interchangeable Sunglasses - Polarized

This is a great fit for me. I have a medium to large head and they fit great. They are light and the interchangeable lenses are too cool. I have some other Smiths and they have the True Color Grey polarized lenses(the grey lenses offered on some of these glasses). I like the grey for the unaltered world view. I tried the brown lenses with these glasses and they really sharpen things up. They filter out blue light and while they do alter they way things look they help to show contrast and sharpen up vision. Depending upon your activity you should pick the lens for you but you really can't go wrong with these sunglasses.
