I'm still not sure how I like the look of these as prescription glasses but I've gotten compliments. Also, since they're sunglasses, Oakley does not make my prescription for them so I had to settle for Crizal lenses. Another thing I'll pick at is the positive red lenses, I'd rather have dark grey myself. Overall, the frame is very comfortable and light and make for a great prescription frame as far as comfortability goes. Not to mention, Tinfoil sunglass frames cost hundreds less than Tincup prescription frames.
