Our Photochromic Goggles Cycling is equipped with photochromic lenses that change the transparency according to the light conditions. The range of performance of such lenses is inferior to interchangeable ones, but they are good if you do not want to bother and constantly change glasses. Some lenses have a special coating so that the glasses do not fog up or they are covered with a water-repellent layer (the rain just rolls off). Be sure to check that there is broad UV protection. You can order Photochromic Goggles Cycling made according to your healthcare professional's prescription.
