What is the different among central, fringe and peripheral vision?

Central vision is a narrow five-degree cone (see figure below) that makes up only three percent of a driver’s total visual field. It provides detail of objects and conditions and is the primary visual function employed in targeting information. Comprising a much wider conical field of vision, fringe vision is used to judge depth and position. It provides information about objects close to the travel path and lane position. Peripheral vision is conical in shape around the other vision fields. It detects color and motion, providing you with information about moving or stationary objects that could be threats along the intended path of travel. It also gives you a sense of the speed you are traveling.
