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.
