Wayfarer (Sunglasses)

Thickness is the point. Molded from acetate, a plastic made from cotton and wood pulp that can be cut thick and polished, the frame carries a heavy top rim above each eye and slopes inward toward the bottom. The lens is a trapezoid rather than a rectangle. That top rim is what makes the shape register so strongly on a face. It blocks overhead sun better than a thin wire rim ever will.

Several details carry over from the original 1950s design. The temples splay outward as they leave the hinge instead of running parallel, which grips the sides of the head without needing a hook behind the ear. Metal rivets set into the front near the hinge are visible from outside and anchor the hinge into the acetate, and cheap copies fake them with molded bumps. Since acetate cannot carry adjustable nose pads, the bridge is molded to one fixed shape. That fixed bridge decides whether a wayfarer fits your nose or slides down it all day.

Square frames share the flat brow but keep the sides parallel and the corners sharp, so they read more formal. Aviators cover similar territory in thin metal and hang lower under the eye. Cat-eye frames start from the same acetate slab and then sweep the outer corners up. Compared with all of them, this shape suits round and oval faces most reliably, because straight lines balance soft ones.

Everyday city wear, festivals and travel suit a frame this durable, and acetate takes color and tortoise patterning that metal cannot. Small or narrow faces often disappear behind the thick rim. A bridge that does not match your nose is a reason to walk away, since nothing on the frame adjusts.

Press a thumbnail into the inside of a temple: real acetate feels dense and slightly warm. By comparison, cheap injection-molded plastic sounds hollow and feels light. Hinges should have at least five interlocking barrels, as three-barrel hinges loosen inside a year. An optician can heat and reshape acetate temples for a better fit, which is worth asking for rather than living with a loose pair.
