I love Shady Rays sunglasses. They've got plenty of different styles, all their lenses are polarized, they're not too expensive, and, if there's ever an issue, they will stand behind them and will ship you a new pair for free. I wore a pair with mirrored lenses to the beach this summer, and the salt scratched up the mirroring. I filed a claim online, and they sent me a brand new pair for free. The kicker is, if you lose or break them, they will send you a new pair for just the cost of shipping, which is usually less than 9 bucks.

I've got more pairs than I want to admit, because they keep coming out with cool new styles and lenses!
