    The glasses look amazing and my prescription is perfect. I've always wanted prescription sunglasses but they've never been affordable. These are beautiful and very affordable. I liked them so much I ordered two more pairs of regular glasses.

    These frames have an excellent black and white tortoise color design for a modern twist on the standard tortoise colors.
