What Exactly is Antireflective Coating?

To improve both vision and appearance an antireflective coating (AR coat) is applied. AR coating consist of several layers of metal oxides applied to both sides of the lens. Each layer progressively blocks reflections from the lens. This benefits the patient in several ways. The patient will see a reduction in nighttime glare, a great safety benefit when driving at night. The coating will also help cut the glare created from a computer screen or an overhead reading lamp.

Additionally, an antireflective coating reduces reflections on the lenses themselves when viewed by another person, creating cosmetically more natural looking lens on the face. With anantireflective coating, lenses appear non-existent in photos and are unnoticeable to people looking at the wearer.  All of these benefits are even greater with higher prescriptions.

With sunglasses lenses, an AR coat applied to the back surface of the lens helps reduce the reflections of light that enter from behind the wearer and bounce off the tinted surface into the wearer's eyes. The darker the sun tint, the more noticeable theses back surface reflections will be. An AR-coated sun lens is much more visually comfortable than an uncoated sunglass. We highly recommend a back-surface AR coat on all sunglasses.
