Range vision refers to the ability of an individual or organism to perceive or see objects or events that are situated at varying distances from their current position. It involves the visual perception of objects or events that are within one's field of view, but at different distances or depths.
Range vision relies on the coordination between the eyes, brain, and other sensory systems to accurately determine the relative distances and positions of objects or events in the visual field. This perception of depth is often accomplished through the process of binocular vision, where the eyes work together to provide a three-dimensional representation of the surroundings.
Humans and certain animals possess range vision as an essential sensory mechanism for understanding and navigating their environment. It allows individuals to gauge the proximity and distance of objects or events, contributing to depth perception and spatial awareness.
Range vision can be further enhanced by the use of visual cues, such as size, perspective, texture gradients, motion parallax, and stereopsis. These cues help individuals to accurately estimate the distances of objects or events and navigate their surroundings effectively.
In summary, range vision refers to the visual ability to perceive objects or events at varying distances within one's field of view. It plays a crucial role in depth perception, spatial awareness, and navigation.
