GMS Optical shorter sized adhesive contoured silicone nose pads are perfect for smaller frames and children’s eyeglasses. They have a standard silicone nose pad thickness of 1.8mm, but a length of just 13mm, making them just the right size for kids glasses and any other smaller sized plastic frames, including sunglasses. They help prevent glasses from slipping on the face while making them more comfortable to wear. INSTRUCTIONS: Wash your hands before removing pad from backing. Use a dust-free cloth or paper towel and denatured or isopropyl alcohol to clean any dust or oils from the surface of glasses. It is important to remove any trace oil on frames for best adherence. Remove pad from backing and avoid touching pad backing with fingers. Oils from hands will reduce pad stickiness. Place pad on bridge of glasses and press down. Repeat on the other side.
