Lens coatings can enhance the durability, performance and appearance of your eyewear lenses. This is true whether you wear single vision, bifocal or progressive lenses. If you are thinking about purchasing new eyewear, here are lens coatings and treatments you should consider.
Anti-reflective coating (also called AR coating or anti-glare coating) is a microscopically thin multilayer coating that eliminates reflections from the front and back surface of eyeglass lenses.
By doing so, AR coating makes your lenses nearly invisible so people can focus on your eyes, not distracting reflections from your eyeglasses.
Anti-reflective coating also eliminates glare caused by light reflecting from your lenses. With reflections eliminated, lenses with AR coating provide better vision for night driving and more comfortable vision for reading and computer use.
AR coating is highly recommended for all eyeglass lenses, but particularly for polycarbonate and high-index lenses, which reflect more light than regular glass or plastic lenses if anti-reflective coating is not applied.
Also, aspheric lenses, which have flatter curves than regular lenses, often cause more noticeable reflections, so AR coating is highly recommended for these lenses, too. And AR coating is beneficial when applied to the back surface of sunglasses to eliminate “bounce-back” reflections when you are facing away from the sun.
For the best possible comfort in all lighting conditions, eye care professionals usually recommend applying anti-reflective coating to photochromic lenses. AR coating improves light transmission through the lenses for night driving and helps photochromic lenses reduce glare in bright sunlight.
Very important: Always make sure you discuss and make decisions about your eye care based upon a formal appointment with your optician or doctor.
