1.67 Anti Reflex Photochromic Lens For Eye Protection Antiglare Optical

The 1.67 spin coating is achieved by evenly applying a layer of intelligent color-changing factor on the surface of the lens. After the color change, the depth of the color will not vary due to different lens thicknesses. This color-changing method makes the color after the change more uniform, suitable for consumers who pursue both aesthetics and practicality. At the same time, the refractive index of 1.67 is also suitable for people with high prescriptions

Features of 1.67 Anti Reflex Photochromic Lens For Eye Protection Antiglare Optical

Color change principle:

The photochromic lense is mixed into the raw material of the lens in the manufacturing process. Spin coating lenses are coated on the surface of the lens with a film layer containing discoloration factor.

Color change effect:

The discoloration rate of photochromic lenses is slower, and the discoloration rate of spin coating lenses is faster and the color is deeper.

Process technology:

The photochromic adopts the traditional mature process, which has strong wear resistance and high temperature resistance, but there may be uneven discoloration.

The spin coating has strong adhesion, high firmness, more uniform and rapid discoloration, and longer service life.

Price:

The price of photochromic is relatively low, and it is the first choice for mass consumption. The spin coating lens is higher, suitable for people with higher requirements for lens aesthetics.
