SCRATCH + UV PROTECTION

UV light is invisible to the human eye but can, in excess, cause retinal burning and scarring. Most sunglasses are already designed to block a high level of UV radiation; other lenses, depending on their function or lens material, may also block some UV rays. If your lenses do not specifically state their UV screening level and you spend time outdoors, an additional UV coating will offer protection and peace of mind. Anti-UV treatment is not necessary on polycarbonate lenses because it is an inherent property of the material.
