Definition: A type of optical coating applied to the surface of lenses and other optical devices to reduce reflection. Anti-reflective coating (AR coating) is made of several layers of film metal oxides that are layered on the surface of the lens. Each layer is chemically engineered to block reflected light. This causes the intensity of the light reflected from the inner surface and the light reflected from the outer surface of the film to be nearly equal, canceling each other out and eliminating glare.
AR coating increases the amount of visible light available to the eye, which improves the efficiency of vision.
