Can Photochromic lenses replace sunglass lenses?
Photochromic lenses get dark outside but are not meant to replace as a sunglass lens. Some studies show that photochromic lens wearers are more likely to own sunglasses as a second pair of glasses because when being worn behind a windshield, the level of activation is not as high because most windshields block UV rays. Sunglasses are a specialty product for specific need. Photochromic lenses are worn for patients to see comfortably in any light.
