Anti-reflective coating

Mirrors a widespread problem is after the glare of the Sun, after returning to bright light is light to the rear of the lens and reflected to your eyes. Role of anti-reflective coating is this reflection of reducing lens to light. As with scratch-proof protection layer, anti-reflective coating is on the lens is a very strong, very thin film layer. Anti-reflective coating material between the refractive index of air and glass. This makes the film surface and the outer surface of the intensity of reflected light is almost equal. When the film thickness is approximately the wavelength of one-fourth, respectively from the film inside and outside surface reflects light through destructive interference will cancel each other out, so as to minimize the glare you see. Anti-reflective coating has been applied to the refractive lens front surface of the mirror and the Sun to remove the lenses reflect light generated by the "hot spots".
