Sunglasses frame The blue colour of the frame perfectly matches a cool skin tone and light brown, black or light blonde hair. Square frames are an ideal choice for those with a round, oval or triangular face shape. The frame of the sunglasses is made of a combination of metal and plastic. It offers high durability, stability and extraordinary sty­le. 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. 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.
