Why Choose AR Coated Lenses For Your Eyewear

AR Coated Lenses

We have had heard of the term “anti-reflective coating” but what exactly is this coating all about? In this blog, we would learn about some aspects of this coating & its usefulness in our daily lives. An anti-reflective (AR) coating is an optical layer, applied over the lenses to reduce the amount of reflection. This greatly enhances the clarity & visual appeal of the lenses. Due to this reason, this coating is applied to the lenses of eyeglasses and sunglasses.

 

How anti-reflective coating works?

The anti-reflective or AR coating is a very thin but hard film which is applied on the lenses. The “film” or coating is composed of a material, with a refractive index somewhere between glass and air. This leads to an equal amount of light that is reflected, from the inner & outer surface of the film. Both the reflections cancel each other out, therefore, reducing the chances of glare.

What are the benefits of the anti-reflective coating?

Apart from reducing the glare, this special coating imparts various other benefits which are important to be considered.

·         Imparts clarity of vision: By eliminating the glare, AR coating allows more light to pass through the lens, thus leading to a much clear vision.

·         Adds to your appearance: Due to the absence of reflections, this coating helps to eliminate the white patches of light which overshadow your lenses – hence delivering a clear view & perfect appearance.

·         Prolongs the lifespan of lenses: AR coating is capable of protecting the lenses from any scratch or smudge. This leads to a long-lasting lifespan of the lenses, which means you would be changing the lenses less frequently.

·         Offers protection against UV rays: AR coatings not just eliminate the glare but also offer protection against the harmful UV rays of the Sun. Thus, saving you from the harmful UV rays that often get reflected from the surfaces such as sidewalks/car hoods/mirrors/water sources etc.

 

Which AR coating should I choose?

Today, every AR coating manufacturer has their own “formula” for creating the AR coated lenses. Anti-reflection coating generally comprises of several microscopic layers which facilitate in the refraction of the light. More the number of layers more the reflections eliminated.
