Sunglasses frame The blue colour of the frame perfectly matches a cool skin tone and light brown, black or light blonde hair. Rectangle frames are an ideal choice for those with an oval or round face shape. The frame of the sunglasses is made of high-quality plastic, which offers high durability, comfortable wearing, and an exceptional look. 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 lenses are made of plastic, whose undeniable advantages are the light weight and crack resistance. Thanks to the unique technology of polarised lenses, the sunglasses offer perfect vision, eliminate unwanted reflections and protect the eyes from ultraviolet radiation. They improve resolution, depth of field and focus. Polarising sunglasses filter out dangerous reflections and reflected white light. This makes them particularly suitable for drivers, cyclists, skiers and anglers. But they are just as suitable as a fashion accessory for everyday wear. 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. Accessories The cloth supplied is ideal for cleaning and caring for sunglasses. For more information, follow our blog where we keep you up to date on the latest technologies and trends.
