You can't beat Ray-Ban RX7031 eyeglasses for casual comfort. Made of acetate, these frames are thin but strong and feather light. 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.
