What exactly are these lenses? How do they benefit long term eyeglass wearers? An all-in-one prescription sunglasses and prescription eyeglasses solution with special lenses manufactured with a special mix of chemicals is included in Photochromic lenses. When exposed to ultraviolet (UV) rays, these react with one another. Essentially, when outside and exposed to sunshine (aka ultraviolet rays), the lenses darken into sunglasses. As soon as the UV is removed slowly return to being regular indoor eyeglasses. On the amount of UV light, the amount of shade the lenses turn is dependent. The general timeline is that they will respond to either the UV rays, or the absence of them, within one minute, and then gradually darken or fade over a course of fifteen minutes; however, the full visual effect is usually seen within five minutes. To protect the eyes against harmful UVB and UVA rays, an important side note is that, photochromic lenses will darken enough, when outdoors.

In a wide range of materials, photochromic lenses are now available, and are usually very lightweight with advances in manufacturing capabilities and technology.
