Sunglasses lens The pink lenses accentuate details and improve spatial perception. They slightly reduce color resolution. The lenses are made of high-quality mineral glass, the undeniable advantage of which is its exceptional resistance to scratches. Mineral glass is characterized by its excellent optical properties compared to other materials used for the production of sunglass lenses. Mirroring of lenses is characterised by a highly reflective surface of the lens. It reduces the amount of light that enters the eye. This ability makes mirrored sunglasses extremely suitable in very bright or glaring environments – for example, on sunny days or when skiing. The mirroring provides great visual comfort but can slightly distort colour perception. The sunglasses feature photochromic lenses that adapt to the level of UV radiation. Depending on the UV exposure, the lenses automatically darken within seconds. As soon as the intensity of the UV radiation decreases, the lenses become brighter to clear again, depending on the specific model of sunglasses. UV protection is completely maintained during these transitions. In this way, the light-sensitive lenses offer excellent UV protection in different climatic conditions, at any time of the year. Learn more about photochromic technology in our Complete Guide To Photochromic Lenses. The shades have UV 400 protection, which provides 100% protection from sunlight. The lenses of the sunglasses feature a category 2 sun filter (light transmission 18 – 43% ). They are slightly lighter tinted than usual and are suitable for medium sun radiation and for casual wear.
