About the product
Photochromic lenses darken when they come in contact with Ultraviolet rays (eg Sun light) and they become clear when taken out of the rays.
Transition lenses are same as photochromic lenses but they are darker than photo lenses when exposed to Ultraviolet rays.
Blue Block Lenses prevent light rays of up to 400nm from penetrating through the lens. They are required by people who spend long hours using their computers or other devices.
