Anti-Reflective Coating is a multilayer coating applied to any lens material to reduce glare and enhance the appearance of the lens. AR coatings will have a slight blue, green, purple, or gold appearance, depending on the brand. There is a basic AR and a premium AR. The premium AR is warrantied longer, more scratch resistant, and more hydrophobic than the basic AR coatings.
Polarized Lenses are sunglass lenses that are designed to eliminate reflective glare and increase contrast acuity. These are great lenses for any type of water sport or winter driving.
