Has this ever happened to you? You're at your job, working away until the clock strikes 5pm.

Pretty sure, we've all been there. Only this time, you reach for your bag and realize you forgot to pack your sunglasses! Well, we've got a solution for that.

What Are Photochromic Lenses?

Don't let the fancy word scare you! Photochromic lenses are actually quite simple to understand. They are glasses lenses that transition from clear to dark when exposed to UV rays. You've probably already heard of phrases like transition lenses or light-responsive lenses. Photochromic lenses are the same thing, just one of the official terms for these adaptive lenses.

How Do Photochromic Lenses Work?

While indoors, your glasses with photochromic lenses will remain transparent. You'll have your RX prescription already in your lenses, so you can see clearly. However, when you step outdoors and UV rays from the sun hit your glasses, the molecules inside your photochromic lenses will activate and thereby darken. Whenever your outdoor adventure is done and you go back indoors, your lenses will transition back into its clear state. Pretty cool, right?
