What aspects does depth perception measure?

Depth perception primarily measures binocularity and the ability to perceive distance. Binocularity refers to the use of both eyes in coordination to perceive a single, three-dimensional image. This coordination is essential for accurately judging distances and for various visual tasks, such as catching a ball or reaching for an object.

The ability to perceive distance involves interpreting various depth cues obtained from our visual input, including binocular cues (like retinal disparity) and monocular cues (like size perspective or motion parallax). Through these mechanisms, depth perception allows individuals to accurately gauge how far away objects are and to navigate their environment effectively.

The other choices focus on different aspects of visual function, such as color differentiation, visual clarity, or fatigue, which do not directly involve the measurement of depth perception itself.
