Photochromic lenses, are the lenses that darken in the sunlight and lighten in softer light or the dark. These lenses have been around for a decade or more, and they offer the convenience of sunglasses without having to wear them over your prescription glasses or having to constantly switch between the two.

   -Convenient – Transitional lenses are very convenient because they save you from having to carry around two pairs of glasses and having to switch between them to meet different needs. With transitional lenses, you can wear sunglasses while driving and still be able to read important street signs.

Product Feature

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.

Modern photochromic lenses tend to be plastic and instead of silver chemicals they contain  organic (carbon-based) molecules called naphthopyrans that react to light in a slightly  different way: they subtly change their molecular structure when ultraviolet light strikes them.
