Dare to be square when you reach for these Ray-Ban RX5375F Alternate Fit eyeglasses. Crafted in hypoallergenic acetate, the full-rim frames are lightweight, comfortable, and retain a high luster through years of wear. The shark fin temples widen at the tips for a non-slip grip, and come with flexible spring hinges for a secure fit. These square glasses boast an alternate fit design—ideal for the man with a wide nose bridge and high cheekbones—so they won't pinch or mark the cheeks. A raised Ray-Ban logo at the temple and rivets on the endpoints put the finishing touches on these Ray-Ban glasses.
