Gucci works its signature horsebit detail into every collection, and you'll find it on the gold-tone arms of these square-frame optical glasses. Designed with a classic keyhole bridge, they're made from lightweight tortoiseshell acetate and have comfortable covered tips. From aviator to oversize, Gucci’s eyeglass selection features an eclectic mix of silhouettes in metal or acetate frames. Each frame is completed by transparent sample lenses designed to maintain the style’s shape.
