Product Description

Photochromic:

Photochromic lenses are available in nearly all lens materials and designs, including high indexes , bifocal and progressive. An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays. Because a person's lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life, it's a good idea to consider photochromic lenses for children's eyewear as well as for eyeglasses for adults.

First let's cut through the jargon. The word "photochromic" comes from two Greek words: "photos" meaning light and "chroma" meaning color. So photochromic simply means something that changes color in response to light. In those days, photochromic glassworked a bit like pieces of old-fashioned, photochromic film.

Blue cut lens:


Ultraviolet (UV) is part of the light transmitted by the sun, which is very important to our daily lives. However,
over exposure to UV radiation, such as from sunlight or sunlamps, could have negative effects to our skin and eyes.

Eyes are the only internal tissues of the body directly exposed to UV light. Millions of people get eye diseases every year from prolonged UV exposure.
