The reflection of the lens can reduce the light transmittance and form an interference image on the retina, which affects the quality of the image and the appearance of the wearer. For example, the appearance of the lens is obviously vortex, and the eyes of the wearer cannot be seen by the opposite light. The coated lens is to use the new technology of optical film and vacuum to coat a certain thickness of single-layer or multi-layer optical film, so that the lens can obtain some new excellent performance that was not originally available, so as to improve the ability of the lens to reflect light. The effect of enhancing or reducing light transmission increases the light transmittance of the lens to 98%. So do you know any of its advantages? Follow the editor of CB Layer Coating lens to have a simple understanding!

Coated lenses can reduce the reflected light on the lens surface, see clearly, reduce the specular reflection light, increase the light transmittance, and solve the problem of taking pictures under strong light with glasses, and also increase the aesthetics.
Coated lenses can prevent damage to eyesight caused by ultraviolet, infrared, and X-rays. Wearing glasses with coated lenses is not easy to get tired. The eyesight of the staff in front of the fluorescent screen can be protected. If the ordinary lens can be seen clearly, there is no need to add a film. If you want to add, the resin lens can be added with an anti-reflective film or a hard film. The glass lens generally only has an anti-reflective film.
The above is the introduction of the CB Layer Coating lens editor: an introduction to the relevant knowledge about the advantages of coated lenses.
