Spin Coating technology is used to evenly coat discoloration factors on the outer surface of the lens to make the color more uniform and stable after discoloration, which can produce open and close reaction to light in a short time and protect eyes from strong light damage.

The appearance of film color changing technology has greatly expanded the market of color changing lenses because of its superior color changing performance:

1. Faster discoloration and fading

2. The background color is lighter and the color change is deeper (also known as bottomless color change)

3. Not limited by diopter
