Photochromic sunglasses – what does photochromic mean?


Photochromic sunglasses have lenses with a variable tint. Photochromic lenses change tint depending on light conditions or weather. In bright or sunny conditions the lens will be darker blocking the bright light from obscuring or interfering with your vision. In dull or overcast conditions the lens will be lighter, allowing more light through so you can see better.
