Final answer:
Central vision, also known as foveal vision, is provided by the high concentration of cones in the fovea, and is crucial for driving as it allows for the perception of fine details.
Step-by-step explanation:
The fovea is the region in the center back of the eye that is responsible for acute vision, often called central vision. The fovea has a high density of cones, which are most concentrated in this region; the fovea is completely devoid of rods. Cones are responsible for high resolution and color vision, and operate best in bright light. In the context of driving, this central vision is crucial as it allows for the perception of fine details, essential for recognizing traffic signs and potential hazards. The five-degree cone of vision that makes up only three percent of a driver's total visual field and provides this crisp central vision is known as the foveal vision.
