Sunglasses frame The gold colour of the frame perfectly matches a warm skin tone and dark brown 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 metal, which holds its shape well and offers high stability and a unique look. Sunglasses lens The yellow lenses enhance the contrast, for example in fog or when watching objects against the sky. Due to the distorted distance and reduced ability to distinguish colors, they are completely unsuitable for driving. 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.
