1.56 Semi Finished photo grey Optical Lenses

Short Description:

The glass lens of the color-changing lens contains a certain amount of silver chloride, sensitizer and copper. Under the condition of short wave light, it can be decomposed into silver atoms and chlorine atoms. Chlorine atoms are colorless and silver atoms are colored. The concentration of silver atoms can form a colloidal state, which is what we see as lens discoloration. The stronger the sunlight, the more silver atoms are separated, the darker the lens will be. The weaker the sunlight, the fewer silver atoms are separated, the lighter the lens will be. There e is no direct sunlight in the room, so the lenses become colorless.

Production Introduction

According to the process, there are two kinds of color changing lenses: base changing and film changing. The advantage of base changing is that it is mixed with the monomer raw material, and the whole lens is full of color agent. The advantages are longer time of color changing and high temperature resistance. The advantage of film transformation is that a little thin color agent is sprayed on the film layer, which is characterized by a light and nearly colorless base color and a good appearance at the time. This process is also known as spraying film change, will soak the lens in the color change potion, inside and outside the film layer are added to the color change layer, color change is more uniform.
