Photochromic Lenses: Adaptive Eyewear for Every Environment Photochromic lenses are a revolutionary optical technology designed to adapt to changing light conditions. These lenses automatically darken when exposed to ultraviolet (UV) radiation and return to a clear state indoors or in low-light environments How Do Photochromic Lenses Work? Photochromic lenses contain light-sensitive molecules, such as silver halides or organic compounds, that react to UV exposure. When exposed to sunlight, these molecules undergo a structural change, causing the lenses to darken. Once UV light diminishes, the molecules revert to their original state, restoring the lenses to clear transparency.
