Anti-reflective coating, or AR, has become an increasingly popular addition to prescription eyeglasses and sunglasses. These coatings provide a wide range of benefits, both cosmetic and optical. AR coating allows for more light to pass through the lens resulting in a lens that looks better due to less reflection. It actually increases visual acuity. These benefits are not without a slight trade-off. AR coated lenses tend to appear dirty quickly and scratch easier than uncoated lenses. Although the anti-reflective coatings of today are significantly tougher and easier to clean, the coatings still require attention in order to keep them in tip-top shape. Modern AR-coated lenses often have a hydrophobic layer to repel water and a scratch resistant coating to increase durability. Keep in mind that there are numerous brands of AR coating that differ greatly in quality. Always consult your eyeglass provider or the lens manufacturer for proper cleaning instructions.
