What are Photochromic / Transition Lenses? 

Photochromic lenses are eyeglass lenses that darken when exposed to UV light. They present a very wearable option for people who don’t want to have to switch between sunglasses and untinted prescription lenses.The name “photochromic” comes from two Greek words, “photos” meaning light, and “chroma” meaning color. In other words, the name literally means color changing in response to light, which is what happens with these special lenses. 

The photochromic/Transition lens is also called light-adjusting lenses because of its property to adapt to changing light conditions. 

 

 

Do photochromic lenses block blue light from your screens too ?

Yes, you need to choose the anti-blue light option when you make a customization. An anti-blue light filter built into the photochromic lens itself makes these lenses optimal for protection from blue light while you are working on your computer or other screens.
