Carbon fiber is an incredibly strong material artificially obtained by scientists. Its basis is elemental carbon, the percentage of which reaches 80%. Combining high strength, carbon has an unusually light weight: it is almost 2 times lighter than aluminum alloys and 5 times lighter than iron. The use of Carbon Fiber in the manufacture of ultra-thin frames for sunglasses allows for unprecedented comfort and ease of wearing. Carbon, unlike metal alloys, is a "warm" material, similar to wood or a natural horn which makes it pleasant in contact with skin. Besides, the use of carbon fiber in the production process has led to the creation of glasses that follow the contour of the face which is important for sports and wraparound models. World famous manufacturers and designers actively use this unique material in combination with various metals and plastics.
