Some refuse to pay for expensive sunglasses, I refuse to waste my money on cheap ones. It's a matter of where you place your values. I will destroy ten pair of cheap sunglasses and spend the same amount of money in a quarter the useful lifespan of a pair of good sunglasses like Oakley's. I'm a photographer, so I'm big on protecting my eyes to begin with. I simply will not wear cheap sunglasses that might shatter in a crash.
