Sunglasses frame The black colour of the frame perfectly matches a cool skin tone and light blonde, light brown or black hair. Round frames are an ideal choice for those with a square or oval face shape. The frame of the sunglasses is made of metal, which holds its shape well and offers high stability and a unique 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 blue lenses enhance the contrast and minimize light reflections. Tennis players will also appreciate them, as they emphasize the contrast of the yellow tennis ball and the white background. The sunglasses have gradient lenses that are tinted from top to down where the bottom of the lens is the lightest. The darkest tint at the top allows filtering of direct sunlight and the lighter tint at the bottom ensures sufficient visibility. This lens treatment provides better orientation in space and is ideal for drivers, for example, because it allows clearer vision in the lower part of the lens while reducing glare from above. 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 shades have UV 400 protection, which provides 100% protection from sunlight. The lenses of the sunglasses feature a category 3 sun filter (light transmission 8 - 18% ). They are suitable for intense sun exposure on the beach or in the city.
