Last year I bought a set of these Berkley sunglasses at War-mart. they were cheap ($5) and I needed a pair. I was actually very Surprised they were 100% UV and polarized as well. I got them so if i lost them on The boat it would not be a big deal, and they have lasted me over a year without breaking. They also wrapped completely around my eyes so no unfiltered light comes in I found them in the fishing section. A pair would be good for a BOB or any use.
