Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays. It's a good idea to consider photochromic lenses for children's eyewear as well as for eyeglasses for adults Because a person's lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life.
Trending in the field of lens making, high tech improvements in progressive lenses have created a smooth and consistent transition between differing lens strengths within the lens itself. Also known as “multifocal” or “varifocal” lenses, they offer all of the improvements of the old out moded bi- or trifocal lenses without the drawbacks of heavy weight, lens thickness and bulky transition lines their predecessors had.
