The Ray-Ban RB5375 eyeglasses bring a modern edge to classic square frames. Built from durable acetate in a range of bi-layer color combinations—from striped havana to translucent blue tones—these frames feature the clean lines and structured angles that make square shapes so versatile. The full-rim design shows off subtle gradient effects in the acetate, while silver rivets at the frame front and the embossed Ray-Ban logo on each temple add signature detailing. These frames are designed for everyday wear. Flex hinges provide the give you need when you're putting them on and taking them off, reducing stress on the frame and keeping the fit secure without pressure points. The acetate construction keeps weight down while maintaining durability—a combination that matters when you're wearing glasses from morning to night. Available in two lens widths (51mm and 53mm) with an 18mm bridge, the RB5375 is built to fit medium face shapes comfortably. The square shape works particularly well for round and oval faces, adding definition and balance. Ray-Ban designed the RB5375 with a soft square profile—not aggressively angular, but structured enough to create contrast. The result is a frame that transitions easily from work to weekend, pairing as naturally with a button-down as it does with a T-shirt. These frames are prescription-ready and compatible with single-vision, progressive, and blue-light filtering lenses. The full-rim design accommodates a wide range of prescriptions, and the acetate material can be adjusted by an optician for a custom fit. Ray-Ban includes demo lenses with logo printing; you'll replace these with your prescription lenses.
