Question

What is one of the three functions of the central vision area of a driver?

Answer 1

Although the focus vision is the one responsible for the targeting function, it is the central vision that allows the viewing of the line of sight to the target area. It is the central vision that allows a relative focus for mid distances and blurring of what's around. It is important on a motorway, for example, as what's ahead is the most important once there isn't people or very busy areas around.
