Lens Coating

Lens Coating A. For purposes of this rule the following definitions will apply: 1. Antireflective is a coating applied to a lens to reduce the amount of reflected light and glare that reaches the eye. 2. Mirror coating is applied to a lens that allows the lens to take on the properties of a two- way mirror. 3. Scratch resistant coating is applied to a lens that helps retard crazing of the lens, thus extending the product life. 4. Tint is an opaque or transparent color coating applied to a lens. The parts of the light spectrum that are absorbed by the lens are determined by the color of the tint. 5. Photochromatic coating is applied to a lens that allows the lens to adjust to the amount of available light. 6. Polarized coating is applied to a lens that filters out reflected light and glare. 7. UV coating is applied to a lens to filter out ultraviolet light. B.
