DEFROSTING LENS

A defrosting lens includes a lens barrel having an opening toward an object side, a first lens disposed in the lens barrel and located at the opening, and a heating member. The heating member is for providing a heat source and is disposed between an inner wall of the lens barrel and the first lens. The heating member is arranged along a peripheral edge of the first lens. By raising a temperature of the first lens through the heat source supplied by the heating member, frost formed on the first lens could be removed, thereby a definition of an image captured by the defrosting lens could be effectively improved, and the defrosting lens could be applied in various environments without being limited by the change of climate temperature difference.
