Photochromic lenses are widely known by the brand name of Transitions™ Lenses. These lenses are specially made with a coating that is virtually clear while indoors and automatically darken when outside while providing 100% UV protection. This versatility means patients no longer need prescription sunglasses, clip on shades or take unnecessary risks with non-prescription sunglasses.

However, there are limitations to photochromic lenses. The coating that darkens the lenses is activated by UV light. In some cases, the photochromic lenses may not darken if UV light is being filtered. For example, the windshield of a car will filter UV light, preventing the lenses from darkening.
