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.
Spheric lenses have a single curve in their design, while aspheric lenses offer varying deflection. This unique design make lenses thinner and create an over all flat surface making them esthetically pleasing because they prevent magnifcation of your eyes.
