what is Anti-Reflective Coating?

You have probably heard of an anti-glare or an anti-reflective glare coating about glasses. At most optical stores they can easy cost from $30-$200. So what are they? Hot it works on glasses?

An Anti-reflective coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection. In typical imaging systems, this improves the efficiency since less light is lost.

 Anti-reflective coating (also called AR coating or Anti-glare coating or “AR”), that can be applied to eliminate glare or reflections of light from the front and back surface of your lenses and allow more light to pass through your prescription lenses to eye for good vision.

AR coating is especially beneficial when used on high-index lenses which reflect more light than regular plastic lenses. Usually, the higher index of refraction of lenses the more light that will be reflected form surface of lenses.

For example, when we look at an object what we are really seeing is the light that is reflected off of that object, which is why we can’t see in the absence of light, i.e. in a dark room. The light enters your eye through the cornea and hits a specific spot on the back of your eye – the retina. If you have a refractive error and need glasses it is simply because the light is not hitting your retina. Your eye may be too long – myopia, the eyes may be too short – hyperopia, or your cornea is not in the correct shape – astigmatism. There are other issues like cataracts, glaucoma, diabetes etc. but for the point of this article we’re just talking about those three refractive errors.  When you wear glasses, the lenses are bending the light so that it lands right on the retina and you can see clearly.
