Eyeglasses having negative ions and protection/filter layers

Abstract

Health eyeglasses include a frame front, a pair of lenses mounted at the frame front, and a pair of temples pivotally connected to two opposite sides of the frame front. Each lens includes an optical substrate, which is made from a methacrylic polymer material and provided therein with an anion material. A front surface of the optical substrate is sequentially provided with a layer of UV coating, a layer of blue-light filter, and a layer of anti-fog coating. The frame front and the temples are made from a resin material added with an anion material, and thus can produce negative ions, which are beneficial to human health, so that the eyeglasses can promote the health of a wearer's eyes in addition to the function of optical correction.
