These are some spectacular sunglasses. They have unbelievable lenses that are just crystal clear. Revo polarization is second to none. The fact that Revo uses glass lenses simply sets these apart from almost any other brand. I've owned enough sunglasses to supply a small city and these are in my top 3. I sail a lot and polarized sunglasses are one of the most important tools you can own. After all if you can't see the wind on the water then you are at a huge disadvantage. These sunglasses simply deliver a high quality, clear image without any glare. If I can manage not to break these or drop them in the drink then I will be happy with them for a long time.
