What is all this talk about Anti-Reflective Coatings?

Anti-Reflective coatings not only improve the clarity of vision through your eyeglass lenses, but also makes your glasses more aesthetically pleasing. Both benefits are due to the ability of AR coating to eliminate reflections of light from the front and back surface of eyeglass lenses. With fewer reflections, more light passes through the lens to the eye for good vision and the lenses look more transparent and attractive.

The visual benefits of lenses with anti-reflective coating include sharper vision with less glare when driving at night and greater comfort during prolonged computer use (compared with wearing eyeglass lenses without AR coating). Most premium AR lenses include a surface treatment that seals the anti-reflective layers and makes the lenses easier to clean. "Hydrophobic" surface treatments repel water, preventing the formation of water spots. Some anti-reflective lenses have surface treatments that are both hydrophobic and "oleophobic" (also called lipophobic), which means they repel both water and oil. These combination treatments typically contain fluorinated materials that give the lenses properties that are very similar to those of nonstick cookware.
