What is the purple coating on glasses?

Why My Glasses Have A Purple Glare
An anti-reflective coating (a.k.a AR, anti-glare or non-glare coating) is a widely used addition generally in most modern glasses since it improves its optical properties. However, because it is really a very thin layer put on the lens’s front and back surface, it could get easily scratched, that may degrade its optical properties. Since there is no way to correct the AR coating, you can either replace your lenses or make an effort to take away the damaged anti-reflective coating.

No Glare Or Anti
So, these anti-reflective lenses slice the glare and some quantity of harmful blue rays, thus minimizing ocular fatigue. Generally, regular plastic lenses reflect around 8 percent of light striking the lens surfaces. So, roughly 92 percent of light enters the attention for visual function.
Premium AR coatings beat simply reducing reflections. Polarized – Polarized filters are mostly manufactured from a chemical film put on a transparent plastic or glass surface. The chemical compound used will typically be made up of molecules that naturally align in parallel regards to one another. When applied uniformly to the lens, the molecules develop a microscopic filter that absorbs any light matching their alignment. The lens in the foreground is a polarized filter. As the lens rotates, it almost completelyblocks the light from the hood because of its polarization. Tinted – The color of the tint
