In the past, when you folded your sunglasses in half, it was time for new sunglasses. These innovative shades-in Ray Ban's iconic Aviator style-utilize hinges in the temples and the bridge, allowing them to fold down to half the size of standard sunglasses, making them perfect for travel when space is at a premium. Ray-Ban B-15 brown crystal lenses offer greater contrast in low-light conditions. Ray Ban Folding Aviator sunglasses can be fitted with prescription lenses. Case included. Italy.
