Photochromic Grey lenses The photochromic (light adjusting) lenses automatically adjust to the intensity of the UV light rays. In so, these lenses will change from being 81% clear, when there is no presence of UV light (indoors) to being a pair of sunglasses, when in direct UV light (outdoors). If you want a pair of multifunctional glasses for all purposes, this is the lens type you want to go with. 100% UVA/UVB protective
