Chemical Conversion Coating Technique for Spectacle Lens

眼镜片镀膜,就是在镜片表面镀上具有一定厚度和层数的光学薄膜。光学薄膜赋予镜片本身所不具有的光学、化学和机械能,使某个波段的光减少反射,增加透射,视物更清晰;或使某个波段的光增加反射,减少透过,保护眼睛不受损害;光学薄膜能保护镜片表面不受腐蚀和磨损,同时使镜片有悦目的色彩,增加美容效果。

The coating of a spectacle lens is to coat thin optical coatings with a certain thickness and a number of layers on the lens surface. The optical coating can entrust to the lens the oplical,chemical and mechanical energy,and then make the reflection decrease and transmission increase of light within a certain wavelength and the visual object more clear; or make the reflection increase and transmission decrease of light within a certain wavelength, thus protecting eyes from harmfulness. The optical coating can also protect lens surface from corrosion and abrasion,and make the lens having good-looking colour and inprove the face looks effect.
