| Antireflection coating |
 |
AR coating goes on both sides of an eyeglass lens, and on the backside of a sunglass lens, and it allows light to pass more freely through the lens. AR lenses help to reduce eye fatigue in many situations, particularly while viewing computer screens and driving at night. Normally, approximately 8% to 10% of light is reflected away from the lens, "robbing" you of valuable detail for the eye. Also, as this light is reflected off the lens surface, it creates more glare that further impairs your vision. Anti-reflective coating allows approximately 99% of available light to pass through the lens without interruption, thereby reducing glare considerably.
Actors and newscasters like AR coating because it greatly reduces the glare reflected from camera lighting and flashes. AR coating makes it easier for other people to see the wearer’s eyes, and it makes it easier for the wearer to see through the lens. However, AR coating is more difficult to clean, and more difficult to keep clean.
When anti-reflective coating was first available, the new and imperfect technology caused the coating to flake off, and AR coating developed a bad reputation. Now, however, application methods are far more sophisticated and AR rarely flakes off. However, when exposed to extreme heat (for example, if the glasses are left on the dashboard of a car in hot sunlight), the AR coating can “craze”, developing unsightly cracks. If this occurs, the coating may need to be reapplied. |
