The correct choice is centered around central vision, which is defined as the sharpest and most detailed vision that allows you to see fine details clearly. This type of vision is crucial when performing tasks that require focus and precision, such as reading text or interpreting the information displayed on a GPS device. Central vision is facilitated by the fovea, a small area in the retina that is densely packed with photoreceptor cells, ensuring that the details of what you are looking at are clearly perceived.

Fringe vision, on the other hand, refers to peripheral vision that helps detect motion and objects outside the direct line of sight but does not provide the detail required for tasks like reading. Color vision pertains to the ability to perceive differences in color, which, while important for identifying traffic signals or signs, does not specifically relate to reading or detailed navigation. Situational vision encompasses a broader awareness of the environment around you, helping with overall spatial awareness rather than focusing on minutiae like reading or understanding a GPS display. Understanding these distinctions highlights why central vision is essential for detailed activities.
