Regular photochromic lenses change color when exposed to ultraviolet light. Car windshields are designed to block ultraviolet light, so they cannot be used as sunglasses inside a car. On the other hand, these visible light photochromic lenses use a photochromic agent that reacts to light (visible light), so they change color even inside a car, allowing you to use them as sunglasses. Visible light photochromic lenses change the color of the lenses depending on the amount of light. They change to a light color (approximately 10% density) indoors or at night, a medium color (approximately 50% density) in the car, and a dark color (maximum of approximately 90% density) outdoors or on sunny days. They also have a blue light blocking function that blocks approximately 35% of blue light on average.
