Depth perception is achieved when the two eyes work together, a phenomenon known as what?

• A. Binocular vision
• B. Canthus
• C. Oculi
• D. Conjunctiva

Answer: (A)

Depth perception comes from binocular vision. With two eyes, each eye views the world from a slightly different angle, and the brain fuses these two images into one, using the small differences between them (retinal disparity) to judge distance. This coordinated processing enables stereopsis, the vivid sense of depth you experience. Convergence also helps when focusing on near objects, reinforcing the depth cue. The other terms refer to eye anatomy or structures (the corner where eyelids meet, a form of the word eye, or the membrane lining the eyelids) and don’t describe the perceptual process that yields depth.
