These are great prescription eyeglasses. I suppose you could order tinted lenses and make them sunglasses though they wouldn't be as nice. What's so great (and unique) about them is the frames (arms, specifically) are interchangeable. You can get tons of different colours/styles/prints to fit your mood, outfit, etc. on any given day. The glasses themselves come in many different styles as well. They are reasonably priced and the arms are cheap. I've gotten tons of compliments because they're so original!
