Our nose pads are made from soft silicone and may help provide a more comfortable, cushioned fit by gently adapting to the shape of your nose. The built-in plastic backbone may help keep your glasses securely positioned on the bridge. Designed for screw-in frames, they may help improve stability for prescription, reading, or wire-frame glasses. The complete set with screws and a 3-in-1 screwdriver may help make installation simple and convenient.
