Product Description

Spin coating Lens :  Spin coating Lens 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.

1.74 Lens Full name 1.74 refractive index lens, with high refractive index, high transmittance, high Abbe number characteristics, in the case of the same myopia degree, can significantly reduce the thickness of the lens, reduce the quality of the lens, while making the lens more pure and bright. 1.74 The lens adopts MR-174 material, which not only achieves high refractive index and abbe number, but also ensures good light transmittance, low dispersion and clearer vision. At the same strength, the 1.74 lens is thinner and comfortable to wear.
