I just bought a pair of chief's by Smith. They come with polarcromatic lenses (aka- polarized lenses that change shade depending on the light conditions). I took them pike fishing on Saturday and I was amazed how clear I could see almost every strike! I brought along my polarized Oakley's for comparison. It wasn't even a contest. I will be wearing smiths in the future! Especially since they were only $115 off eBay.
