How do photochromic lenses work?

Do you guys know how they work? It’s the molecules in transition lenses that make the lenses darken. When they are exposed to sunlight, the light-adjusting technology function.

The chloride and silver halide molecules in the photochromic lenses will change their structure for a while when they absorb the UV rays from Sunlight. Therefore, when trillions of molecules make changes, the lenses will change from transparent to dark. That’s the process of eyeglasses turning into sunglasses.
