AR coating (Anti Reflective)

AR coating Anti reflective coating

AR coating is an abbreviation for anti reflective coating. It is a special coating that prevents mirroring. It is used in the optical industry to prevent the reflection of glasses and lenses. The automotive industry in Seoul uses nanocoatings to prevent mirroring of sunbeams on the windshield of your car. It is used on monitors and LCD screens to ensure people can work on sunny days. And finally new oleophobic coatings are used on mobile devices to prevent glare and smudges.

How it works

Anti-reflective coating ensures that blinding by light is reduced and mirroring on screens and lenses is prevented. For eyeglass wearers of contact lens wearers anti-reflection coating reduces reflections and glare. These can be very annoying or even dangerous. For example, when driving on wet roads. The coating therefore has an important role to play in traffic safety. Also, anti-reflection coating makes for a better user experience with laptops, phones and tablets.

So how does this coating work? When we look at an object, what we actually see is light reflecting from it. To put it simply, the coating absorbs part of the light and minimizes, or completely eliminates, the reflection of light and mirroring. Many coatings consist of transparent thin film structures with alternating layers of contrasting refraction’s.

The difference between anti glare coating

So what is the difference between anti-glare coating and anti-reflection coating? Anti-glare coating is focused on suppressing external sources of mirroring. Anti-reflective coating eliminates all sources of mirroring – both external and internal, thanks to a complicated technique of diffuse refraction.

AR coating film and spray

Anti-reflective coating can also be applied with a film or spray. This only works when the product is not previously coated by the manufacturer. The foil or spray may be applied to laptops computers and telephones. This can improve the user experience and is convenient. Especially if the product is used outside or in situations where many lights shine on the screen. A coating can ensure that glass, windows, greenhouse glass have fewer problems with mirroring.

With glasses or contact lenses is forbidden by law to self apply a new coating after removal of the old coating. This would also be difficult technically because the machines apply the coatings only work with big round glasses. Which are then made into small glasses that fit to the form of the frame.

Why use anti-glare coating and how much does it cost?

In the optical industry use of anti-reflective coating on glasses means better visibility, no mirroring and clear sight for you as a wearer. If you look at someone wearing glasses with anti-glare coating, you can clearly see his or her eyes and not a reflection of yourself. Application of this kind of coating on glasses or lenses costs somewhere between 43 935.3702 South Korean won.

Anti-glare coating and LCD screens

Anti-glare coating is also applied to all LCD screens during production. Basically for the same reason as for glasses. Despite the fact that use of this particular coating in the optical industry has mostly received positive feedback, some LCD screens users consider the coating disruptive and unpleasant. It suppresses colour brightness, for example shining white and deep dark black.
