What are Photochromatic lenses?

Photochromatic lenses are eyeglass lenses that change color: from light to dark with the sun. They are lightly tinted indoors, and get darker with the sunlight outdoors. The lens is made in single vision, lined bifocals, trifocals and progressive lenses. There is also the Thin and Dark photochromatic eyeglass lens that works the same way as the regular photochromatic lens, but is thinner and lighter.
