What are Photochromic Lenses
Photochromic lenses (or light-adaptive lenses) are innovative eyeglass lenses that automatically adjust their tint based on UV light exposure. They darken outdoors in sunlight and clear up indoors, offering convenience and protection.
How Do Photochromic Lenses Work?
Science Behind It:
Embedded molecules(e.g., silver halide) react to UV rays, causing the lenses to darken. The process reverses when UV decreases.
Speed & Intensity:
Transition time varies(seconds to minutes) based on brand and environmental factors (temperature/UV strength).
