Anti-reflective (AR) coating goes on both sides of the lens (backside only for sunglasses), and it allows light to pass more freely through the lens. AR coating makes it easier for other people to see the wearer?s eyes, and it makes it easier for the wearer to see through the lens. AR coating is very useful for night driving and for people who look at computer screens. Follow this link to read an article about anti-reflective (AR) coating.
Applying thin-film coatings to plastic requires laying an extremely fragile coating on a soft, porous, and temperature-sensitive substrate. for maximum quality anti-reflective coatings, the coater needs to know the lens substrate, lens manufacturer brand, and type of scratch coating. identifying the lens material enables coaters to formulate their AR process to the substrate?s index and chemical composition. identifying the brand identifies which scratch coating is on the lens. the resins used in a particular lens can also affect the adhesion of AR coatings. lenses with resin that are more stable and less heat sensitive can better accept AR coatings and provide better coating durability.
You have chosed a "stock" lens, and this AR coating is applied by the manufacturer of the lens. Each lens maker has a different proces for AR coating, which is designed to chemically match the plastic of the lens itself, creating a harder coating.
Lenses with AR coating must never by cleaned dry, as this can scratch the coating. There is no "perfect" method for cleaning lenses because any time you touch a lens, you could be pushing dirt against it and scratching it. We have found that the best method is to use a clean, micro-fiber cloth, and rub gently. Lens cleaing solutions could damage the AR coating. You can also use soapy fingers under the sink, but be sure not to dry the lens except with a clean micro fiber cloth.
