How is depth perception defined?

Depth perception is defined as the capability to judge distances and spatial relationships. This ability allows individuals to perceive the world in three dimensions and accurately assess how far away objects are from themselves or from each other. Depth perception is crucial for various daily activities, such as driving, playing sports, and navigating through environments. It is primarily achieved through binocular vision, where the brain combines the slightly different images received from each eye to create a sense of depth. Other visual cues, such as size, motion, and perspective, also contribute to our understanding of spatial relationships.

The other options focus on different aspects of vision; for instance, seeing in low light pertains to night vision or scotopic vision, while color vision refers to the ability to perceive different wavelengths of light as colors. Clarity of vision at a distance generally relates to sharpness or visual acuity. These concepts do not encompass the comprehensive nature of depth perception as it involves distance judgment and spatial awareness.
