personally, I wouldn't ever buy oakley sunglases, they're so gay looking, not to mention ridiculously overpriced. And they think they can justify these prices and trick people with the way they display it - to look like it's out of a fucking james bond movie. If you're going to spend a lot of money on sunglases and want quality buy KAENON.
in this lab i learned: oakley glasses have certified safety glasses rating. you can shoot BBs at them and hit them with a 10 pound dart and they wont break! and they quality of the lens is really good: images aren't distorted from distance, like they are in most curved lenses.
