November 20, 2023 Rachel
Imagine walking into the sun and like magic, your glasses turn into different shades. This fascinating phenomenon is made possible by photochromic lenses, a revolutionary technology that allows eyeglasses to change color in response to ultraviolet light. In this article, we’ll explore the science behind photochromic glasses and their practical benefits.
Learn about photochromic technology:
Photochromic lenses contain special molecules that react to ultraviolet (UV) light. When exposed to sunlight, these molecules undergo chemical changes that cause the lenses to darken. Once the UV rays subside, such as when you move indoors, the lenses return to their clear state. This dynamic process enables individuals to have clear vision indoors and UV protection outdoors without having to switch between regular glasses and sunglasses.
