1.61 Spin Photochromic Gray HMC Optical lenses

Short Description:

Spin coating change Lens :  Spin coating change Lens change adopts spin change technology, which completely subverts the previous basic change technology. Compared with base transformation, it is uniform and has no background color; Compared with the traditional film changing method, it is superior to the soaking method. The color changing liquid and the hardening liquid are placed in different processes, which not only ensures the adhesion of the color changing liquid, fully maintains its color changing tension, but also exerts the hardening fixation effect and strengthens the hardness. With double-layer spin coating technology and hardening protection, the process quality is greatly improved. Advantages: rapid and uniform color change. It is not limited by the material, and any ordinary aspheric surface, 1.56, 1.61, 1.67, 1.74, etc. can be processed into a film-changing lens. There are more varieties, and consumers have more choices.

Basic color changing lens production principle:

Chemical substances of silver halide are added to the raw material (substrate) for making the lens, and the ionic reaction of silver halide is used to decompose into silver and halogen under the stimulation of strong light, which makes the lens colored. When the light becomes weak, it is combined into silver halide and the color becomes lighter.

Production principle of spin color changing lens:

Special treatment was carried out in the lens coating process, the compound was used to spin coating on the surface of the lens at high speed, and the effect of passing or blocking the light was realized by the reverse opening and closing of the molecular structure itself according to the intensity of light and ultraviolet light.



Production Introduction

The discoloration factor needs to be decomposed, absorbed and polymerized, and the discoloration efficiency is low and the discoloration speed is slow.
Photochromic factors of spin change have better photoresponsiveness and faster color change.
