Depth perception
Ability to see objects in 3-D although the images are 2-D
Depth perception is the ability to see the world in three dimensions and to accurately judge distances between objects. It allows individuals to judge the relative distances between objects in their field of view, and to determine whether an object is close or far away.
Depth perception is achieved through a combination of visual cues, such as convergence, binocular disparity, and accommodation. Convergence is the inward movement of the eyes when focusing on an object, which allows the brain to calculate the distance of the object. Binocular disparity is the slight difference in perspective that each eye provides, which gives the brain information about depth. Accommodation is the ability of the eye to change its focus to bring objects into sharp focus, which also helps to determine distance.
Depth perception is important for a wide range of activities, from driving to playing sports. It allows individuals to accurately judge distances and speeds, which is crucial for safe and effective performance. Without depth perception, tasks such as driving, playing sports, or operating heavy machinery can be dangerous.
Overall, depth perception is an essential aspect of human vision that allows individuals to navigate and interact with the world around them.
