Photochromic lenses or more commonly known as Transitions are lenses that are clear indoors but turn darker outside. They are activated by the Ultraviolet (UV) light from sunlight. Because the wind shield of our cars provide UV protection, most photochromic lenses do not turn darker inside the car. There are many brands including those that do turn a bit darker inside the car.
They are a great option for patients that wear prescription glasses and do not want to switch back and forth between prescription sunglasses and their regular glasses.
