Made by Essilor, Crizal Avance is the latest generation of anti-reflective coating. Made with Scotchguard Protector, it is an AR lens that is made to stay clean. Crizal Avancé with Scotchgard Protector lenses offers you the best available AR technology by combining the dramatically improved cleanability of the super-hydrophobic topcoat with the industry-leading, anti-reflective, cleanability and durability benefits of Crizal Alizé with Clear Guard™ lenses along with the unmatched protection of Scotchgard Protector.
Crizal Avance lenses come with a two year anti-scratch warrantee. If they do scratch, you can send them back to us and we will redo them (in the same prescription) at no charge!
that 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. Crizal AR coating is only applied in a Crizal laboratory. This adds approximately 2-3 days to the processing time.
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.
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.
