Sunglasses aren't just fashion accessories anymore and most consumers today are aware about the dangers of sun exposure to eyes. The Ultra Violet (UV) radiation from the sun can damage not only the skin of your eyelids, but also the clear outer parts of the eye; the cornea and conjunctiva. UV exposure also promotes to the development of certain types of cataracts. Individuals can protect their eyes by simply wearing sunglasses that block out 99 to 100 per cent of UV. Such glasses protect the eye from both UVA-and the more harmful-UVB rays.However, not all sunglasses block UV rays. According to a research conducted at Harvard University, "Tinted glasses without UV protection cause more harm than wearing no glasses at all. It is important to look for sun shades with the clear protector which blocks harmful ultraviolet light." And though sunglasses do make for interesting style accessories, it's the quality of the glasses that should actually catch your eye. Aviator sunglasses are a style of shades that were developed by Bausch & Lomb and branded as Ray-Ban. They are characterized by dark, often reflective lenses having an area two or three times the area of the eye socket, and metal frames with bayonet earpieces or flexible cable temples that hook behind the ears. The original design featured G-15 tempered glass lenses, i.e., neutral gray, transmitting 20% of incoming light. The large lenses are not flat but slightly convex. The design attempts to cover the entire range of the human eye and prevent as much light as possible from entering the eye from any angle. Aviator sunglasses, or "pilot's glasses", were originally developed in 1936 by Ray-Ban for pilots to protect their eyes while flying. Aviators were given their name due to their original intention of protecting aviator's eyes. Ray-Ban began selling the glasses to the public a year after they were developed. Today the pilot’s glasses exemplify the roughness and the attitude and are thus the most selling sunglasses for men. The Aviator became a well-known style of sunglasses when General Douglas MacArthur landed on the beach in the Philippines in World War II. Newspaper photographers snapped several pictures of him wearing them. The Aviator sunglasses were also issued and found popular in the French Army. Since the early days of introduction these glasses were meant to be Sunglasses for men, but over the yearaviators have become an iconic symbol and the top most style statement for men.
