Optical lens coating，Mainly divided into three layers，They are wear-resistant coating layers、Anti reflective coating layer、Anti pollution coating layer，These three coating layers，It will make the vision brighter，Even in dim environments, there will be no gray haze，It can also effectively alleviate visual fatigue in the eyes。

Principle of Optical Lens Coating

Wear resistant coating layer：Located in the inner layer of the lens，Can effectively prevent lens wear and tear、Scratch off。Utilizing anti-wear film technology，Various process conditions are applied to the surface of the lens，Form a very hard wear-resistant film layer，Make the lens less susceptible to external impacts，Rupture occurs、Scratches and other phenomena。

Anti reflective coating layer：Based on the fluctuation and interference phenomena of light，Overlay light waves with the same wavelength，The principle is to make light waves cancel each other out。Coat the lens with an anti reflective film layer，Make the reflected light generated on the front and rear surfaces of the film layer interfere with each other，Thus offsetting the reflected light，Achieve the effect of reducing reflection，Thereby improving the pass rate of light。

Anti pollution coating layer：Because after undergoing anti reflection coating，The surface of the lens is prone to stains、Sediments such as oils and fats，So the principle of using a top film with anti oil and anti water properties as a coating for lenses，Make the stain no longer affect the effectiveness of the anti reflective film layer，Simultaneously make the lens have the function of preventing stains and oil stains。

Principle of Optical Lens Coating?Compared to regular lenses, coated lenses，The characteristics of optical performance are very good，Not only can it provide the wearer with clear vision、Wide field of vision，It can also ensure that during the wearing process，The eyes will not be disturbed or harmed by the external environment，Comprehensively protect the health of eyes and vision。
