What are photochromic lenses?

Photochromic lenses are those types of lenses that darken the sunglasses when you are exposed to the sunlight or UV light and when you return indoors it returns to the clear state.

Mainly photochromic lenses are that type of transition medium that conveniently switch from clear lens indoor to the sunglasses depth tint when you come to indoor and vice versa

It typically takes only 39 seconds to fully darken and mainly two to five minutes to return to its clear state. It work as a best replacement lens

How do photochromic lenses work?

Small tiny molecules of halide and chloride are embedded onto the photochromic lens which is visible and clear until it is exposed to sunlight and UV rays. A complete chemical process takes place when it is exposed to sunlight/ UV and starts to move effectively. These molecules completely change when they get darker to the sunglasses shade/ tint.

A chemical process takes place when exposed to sunlight/UV and the molecules effectively move, change shape and absorb the light. This process changes the molecules and they darken to a sunglasses shade/tint, a good seek optics option.

Photochromic lenses will remain in the darkened state while they are exposed to the sunlight/ UV light but molecules will reverse its process completely once the lens is removed from sunlight/ UV rays and returns to its original transparent/ clear lenses.

It will reduce your cost

Transition VII/ Signature

These lenses are completely clear when you are indoors or when you are away from UV rays. But, when you go outdoors, these lenses change to darker shades.
