Anti-scratch protection

Right!

The anti-scratch protective layer is a coating that prevents plastic from being scratched by coating a transparent and strong film on the surface of sunglasses lenses.

Glass is naturally scratch-resistant, but most plastics are not. To solve this problem, the manufacturer has developed a series of methods to plate a transparent and strong film on the surface of sunglasses lenses. These films are composed of diamond-like carbon films (not only scratch-resistant, but also reduce surface friction and reduce water stains) and polycrystalline diamond sintered bodies. Through the ionization process, a thin but very wear-resistant film is formed on the lens surface.
