Fashionable wearing experience and simple and casual style, indispensable fashion items, to search and understand our difference sincerely. Glass is naturally scratch-resistant, but most plastics are not. To solve this problem, manufacturers have developed a series of methods to coat a transparent and strong film on the surface of the lens. Such films are composed of materials such as diamond-like carbon films and polycrystalline diamond sintered bodies. A very thin but very wear resistant film is formed on the surface of the lens by an ionization process. The lenses of reflective sunglasses can be reflected like a mirror. The lens is coated with a very thin reflective coating - it is called a semi-silvered surface because it is very sparse. The term "semi-silvered" derives from the fact that the reflective molecules on the lens are very sparse, and the number is approximately half the number of molecules that make the lens an opaque mirror.At the molecular level, the reflective molecules are evenly dispersed on the surface of the lens to form a uniform film, but only half of the area of the lens is covered by the film.
