Optical lens manufacturers introduce the choice of lens surface treatment and optical lenses：There are many ways to coat the lens surface, which can make your lens look more attractive and improve the light transmittance.
Optical lens manufacturers-Wear coating treatment: This hardening coating treatment can make the optical lens more durable, and the inner and outer surfaces of the lens must be hardened, so as to have better wear resistance.
Antireflection film (also known as composite film): this kind of film subtracts the unnecessary reflected light from the lens, so as to provide you with clear vision, and also make you look more beautiful, because what others see directly is your eyes, not the annoying reflected light.
Crystal drilling: This is a new comprehensive treatment method, which provides a good coating combination. It has the functions of anti-wear, easy cleaning of optical lens and reducing reflected light.
You should tell your eye care professionals (or fitting staff) your hobbies, occupation and taste, etc. as long as the above points are combined, they can determine which kind of materials will provide you with comfortable feeling and clear vision.
Glass lenses: glass lenses are very wear-resistant, but they are heavy and easy to break, so they are not suitable for primary school students and people who often play outdoors.
Refractive index lens: it is recommended to wear for patients with deep luminosity. The optical lens of high refractive index lens is lighter and thinner than the standard lens, but the weight of high refractive index glass will not be greatly reduced, only a little.
