There’s no better place to start your sunglass shopping than with the definition of photochromic lenses. To put it simply, photochromic lenses are high-performance lenses that provide crystal clear vision, whatever the lighting. They’re designed to automatically adjust to the amount of sunlight you’re being exposed to, to provide you with razor sharp vision and ultimate clarity, without any squinting.

To put it into perspective, photochromic lenses automatically darken as the light exposure increases, and they automatically lighten as the day progresses and gets darker. This is a huge benefit to having photochromic sunglasses because the weather changes every minute; every hour; every day; every week; every season and well, you get the idea.

The crazy thing is, people rarely change their lenses. So, they’re stuck with a pair of sunglasses that are only ideal for one type of situation, even though they’re being exposed to several different light conditions each day. Photochromic sunglasses are the solution to maintain maximum protection and clarity, whatever the weather.


The incredible technology behind photochromic lenses

Photochromic sunglasses are able to adapt to various light conditions due to the incredible technology infused into the lenses. With the use of a process called imbibing, unique photochromic dyes are infused into the lenses material, as opposed to being a coating that’s applied. The dyes contain molecules that react to UV light exposure and temperature which allows them to light or darken as needed.
