HOW DO PHOTOCHROMIC SUNGLASSES WORK?

Photochromic sunglasses feature lenses that automatically adjust their tint based on light intensity. These smart lenses are made with special molecules that react to the sun’s UV rays. The higher the UV exposure, the darker the lenses become, and vice versa.

The technology relies on a chemical reaction within photochromic molecules embedded in or applied to the lens surface. When exposed to UV light, these molecules change structure, causing the lens to darken. When UV levels decrease, such as indoors or late in the day, the molecules return to their original state and the lens becomes clearer again.

The key advantage is automatic adaptation to ambient light, providing constant protection without switching lenses. Whether in full sun or shade, photochromic sunglasses ensure optimal vision and full UV protection.
