I love my polarized phototec Tifosi sunglasses. With my contact lenses in my eyes are very sensitive to the light and the polarized sunglasses means I can actually see. Really cuts down on glare. The major negative is they have a narrow range of photosensitivity so even though they can adjust to how much light there is the range isn't very large. It's something like 11-25% light allowed in. I have a non-polarized pair and it lets in 11-90%. I'd still wear the polarized in most riding conditions, though.
