Oakley is one of the world's best known manufacturers of sports glasses and goggles. It all started in California in 1975, when company founder Jim Jannard developed rubber grips for motocross bikes that provided more grip in wet conditions. Today, the same patented material (Unobtanium) prevents Oakley sports glasses from slipping off your nose, especially when you start to sweat in the heat of the action. In fact, Oakley is greatly influenced by Jannard's inventive spirit in other ways, too. The company has filed more than 800 patents. PRIZM is one example. Glasses featuring this technology can filter different frequencies in the light spectrum, depending on the activity, to provide detailed and contrast-rich vision. That's important for recognising hazards on the road in good time, for example. The first glasses were produced in 1980, likewise for the American motocross scene. Nowadays the name Oakley is famous for its wide range of sports glasses and sunglasses of all kinds.
