What does the Photochromic lenses perform?
Photochromic lenses darken when they are exposed in the sunlight, and recover clear color when wearers stay indoor. They are the perfect options for the prescription sunglass wearers. Photochromic lenses have many molecules embedded in them. Because these molecules are transparent, the lenses will be light in the absence of UV light. Due to the presence of UV rays, the molecules react and change. And then the molecules absorb some light and make the lens darken. Generally speaking, lenses will become darker under the influence of brighter sunlight.
However, not every lens is suitable for everyone. For example, the photochromic lenses are not fit for the drivers. Because the drivers need to be clear with outdoor color and views, while the photochromic sunglasses block the drivers from acute judgments.
