How Do Photochromic Lenses Work
The light-sensitive molecules inside photochromic lenses shift their structure when theyre bathed in UV rays, allowing them to absorb more light and give the lenses a darkened appearance. Once the UV light goes away, the process reverses and the lenses become clear again.
These photochromic molecules are sensitive to both the presence and amount of UV light. Theyll change their structure more quickly when exposed to a lot of it, and more slowly if theres only a little bit. Thats why you might notice your photochromic lenses darkening a bit less in the shade than out in the sun.
However, you dont need to be standing directly in a sunbeam to get a dose of UV rays. UV light penetrates the clouds, and your photochromic lenses will still darken under overcast skies.
