The Photochromic Spin Coat Technology

Spin-coating technology makes the photochromic coating on the surface of lens, so color only changes on lenses surface, while in-mass technology make the whole lens change color.

How Do Spin Coat Photochromic Lenses Work?

Spin coat photochromic lenses work the way they do because the molecules that are responsible for the darkening of the lenses are activated by the ultraviolet radiation in sunlight. UV rays can penetrate clouds, which is why photochromic lenses are capable of darkening on cloudy days. Direct sunlight is not required for them to work.

They shield eyes from 100 percent of the harmful ultraviolet rays from the sun.

This mechanic is also used inside most windshield glasses in cars. Windshields are designed this way to help drivers see in sunny conditions. This also means that since the UV rays that enter a car are already filtered by the windshield, spin coat photochromic eyeglasses will not themselves darken.
