Very small button nose pad special application nose pad
Most likely you would see these on a pair of reading glasses. Although, there may be some designer frames with these extremely small nose pads. They are mounted just like the Zeiss nose pad. They slide up onto a thin metal piece(straight piece of metal) nose pad arm. And positioned so that the round part rests upon the user's nose. They measure 6 mm long by 4 and 1/2 mm wide. You can see in the photo that there is a channel that runs lengthwise through the nose pad, this is where you mount this nose pad. These are only available in the Pvc material. Reminder: Always check the mount necessary for your eyeglass frame before purchasing nose pads.
