The moment you step outside wearing Transitions lenses you will understand why they are regarded as the number one photochromic lens worldwide. Rapidly adapting to light condition changes, Transitions lenses adapt from clear indoors to fully dark in the brightest sun. The original Transitions lens introduced people to the balance of wearing one pair of glasses for both outdoors and in.
Today, Transitions lenses rapidly filter light with industry leading photochromic dyes whilst blocking 100% UVA/UVB rays. Unlike sunglasses, which have a set tint, Transitions lenses are constantly adapting to your surrounding light conditions. The constant and smooth transition allows you to see well in all light conditions.
