HD silicone nose pads in a "D" (asymmetrical) shape.
Here are the Asymmetrical, or other known as "D" shaped nose pads in a 19mm length. These are in the "HD" silicone family. "HD" stands for High Density silicone nose pads. These nose pads withstand grease absorption more then the common silicone nose pad, therefore producing a cleaner, longer lasting silicone nose pad. The shape is designed for a specific left and right side nose pad. When mounted properly, the flat edge of the nose pads will run alongside the edge of the frame front. And the rounder (curved section) pointing towards the face. These are available in the screw-in and snap-in mounts only! So be sure to check the proper mount of your eyeglass frame before ordering.
