NEW TYPE OF LENS FOR EYEGLASSES AND METHOD FOR OBTAINING SAME |
摘要 |
A new type of lens for eyeglasses and a method for obtaining the same. The lens is composed of a transparent substrate; a composite layer disposed between the substrate and a layer of precious metal, such as gold, the composite layer is composed of at least two layers. A combination for the composite layer is an anti-reflective layer applied directly to the substrate and made of a metal such as chromium; the anti-reflective layer is advantageously made of silicon oxide.
