I had an old pair of WileyX XL-1 prescription sunglasses, but I broke one of the arms. The lenses from that old pair popped right into the new style of frame. If you've got old lenses and need a new frame, these work great!
Pros: Comfortable, prescription lenses available
Cons: Expensive, fogs up sometimes
