The frame of the sunglasses is made of high-quality plastic, which offers high durability, comfortable wearing, and an exceptional look. Adjustable nose pads allow for a gentle alteration of the position and fit of your sunglasses. The nose pads will adapt to the nose shape and thus provide higher comfort of wear. The nose pads adjustment should always be done by an experienced optician to prevent damage or breaking caused by unprofessional treatment. Sunglasses lens The brown lenses slightly block the blue light, filter reflections and ensure clearer vision. They are versatile and recommended for people with myopia. The lenses are made of plastic, whose undeniable advantages are the light weight and crack resistance. 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.
