- Convergence: Convergence is the inward movement of both eyes when focusing on nearby objects. It helps us perceive depth and judge distances.
- Stereopsis: Stereopsis refers to the perception of depth or three-dimensionality that occurs due to the combination of retinal disparity and binocular vision.
- Binocular Vision: Binocular vision is the ability to blend visual inputs from both eyes, allowing for depth perception and accurate distance judgment.
