Abstract
A clip-on wipers are provided that attach to eyeglasses to prevent the buildup of raindrops or snow on the lenses. It attaches via a clip-on clamp thus allowing it to be removed when not needed. A battery pack, envisioned consisting of AAA batteries supplies power to a two-speed motor, via a control switch. The motor then drives a reciprocating mechanical linkage, which moves two small wiper blades across the surface of the lenses. Such action keeps the lenses free from rain and snow buildup when the glasses are worn outdoors in inclement weather.
