Abstract
Abstract An eye shield that effectively blocks ultraviolet rays is incorporated in a pair of ordinary eyeglasses. The eye shield comprises a combination of a coating or layer of light blocking material on the inner surfaces of the eyeglass lenses and a coating or layer of light reflecting material on the outer surfaces of the eyeglass lenses. This combination of light blocking material and light reflecting material results in zero light transmission through the eyeglass lenses.
