The main functions of each Color Coating:

1) Hard Coating(HMC): increase the hardness of the lens surface, make it more resistant to wear.

2) Anti-reflection Coating(AR): Increase the transmittance of lens visible light and anti-ultraviolet and radiation resistance. 

3) Anti-Dirt coating:

The molecules that break the dirt, make the lenses are more brighter. 

4) Anti-Water, Anti-Seawater, Anti-Fog

Therefore, the main advantages of the lens after coating are:

Coated glasses can reduce the reflective light on the surface of the lens, see the object clearly, reduce specular reflection light, increase the transmittance of light, also solve the problem of wearing glasses under the strong light, but also increase the beauty.

Coated glasses can prevent ultraviolet, infrared, X-ray damage to vision. Wear coated glasses are not easy to fatigue. The eyesight of the staff before the screen can be protected.
