You can't beat Ray-Ban RX7031 eyeglasses for casual comfort. Made of propionate nylon, these frames are thin but strong and feather-light. Ultra-slim shark-fin temples embellish these classically handsome frames, and the saddle bridge sits effortlessly on the nose, making them a comfortable choice. Deeply bent skull temple tips provide a snug fit. The rectangular lenses flatter the features of oval, round, square, and heart-shaped faces. From home to the office to a night out, these Ray-Ban glasses remain an all-around favorite for daily wear.
