A pair of my Smith sunglasses have a polarized green/gray tint. They're not quite as dark as your standard gray polarized tint which is nice in a lot of light conditions, but other than that, not a big difference IMO. I would neither buy a pair for that reason or avoid a pair for that reason. It's a push to me. From an appearance perspective, the ones I have just look gray.
Absolutely. Polarized Oakley Sunglasses are incredibly sharp. No haze, no distortion. Simply vision at its best.
I think somebody hated on Oakley sunglasses earlier in the thread...apparently only poseurs wear them. Funny thing is, they're the best sunglasses I ever owned, made better by the fact that I bought them from Steep and Cheap -- $160 glasses for about $50. I could give a rat's ass about the brand (unless it's Burton - LOL!), these are sweet sunglasses, and I'd recommend them to anyone. Especially if you can score them for $50.
