What does lens coating do to your eyeglass lenses ?
Lens coatings can enhance the durability, performance and appearance of your eyeglass lenses. This applies in all types of lenses like single vision , bifocal or progressive lenses.
1 . Anti-Reflective Coating
Anti-reflective coating (also called AR coating or anti-glare coating) is a thin coating that eliminates reflections and glare from the front and back surfaces of your lenses. This type of coating also decreases halos around light and creates a good cosmetic appearance, making your lenses nearly invisible. AR coating improves light transmission through the lens for night driving .AR coating is highly recommended for all eyeglass lenses, but especially for polycarbonate, high-index and aspheric lenses, which all reflect more light than regular lenses.
2. UV PROTECTION
Another beneficial lens Coating Is UV Protection That blocks ultraviolet (UV) light. Just as sunscreen keeps the sun’s UV rays from harming your skin, UV-protective treatments for eyeglass lenses block those same rays from damaging your eyes.
Overexposure to ultraviolet light is thought to be a cause of cataracts, retinal damage and other eye problems.
Regular plastic eyeglass lenses block most UV light, but adding a UV-blocking dye boosts UV protection to 100 percent for added safety. Other eyeglass lens materials, including polycarbonate and most high-index plastics, have 100 percent UV protection built-in, so an extra lens treatment is not required for these lenses.
Photochromic lenses also block 100 percent of the sun’s UV rays without the need for an added UV lens treatment.
