Unfortunately for me, I can't get sunglasses off the shelf - I wouldn't be able to drive or many other things, because of my bad vision. So, I need prescription lenses. And, I get prescription polarized lenses. So, obviously, they're going to cost a lot more than Maui Jims. Oh wait! I'm not stupid enough to pay $200 for $20 worth of product. So, even with prescription polarized lenses, I spend a lot less. And, oh my flying spaghetti monster, they even stay on my face when it's windy. Like someone above said, get a good pair at JCPenney or some place like that. And, I'd definitely go with polarized lenses - especially if you're ever around water (reflective glare).
