Convergence: Understanding Eye Movement for Single Vision

The simultaneous inward movement of both eyes toward each other to maintain single vision is known as convergence. Convergence is a crucial physiological process that ensures clear and focused vision of nearby objects. When we shift our gaze from a distant object to a near object, the eyes rotate inward, bringing the images of the object onto the corresponding retinal areas. This allows for accurate depth perception and prevents double vision (diplopia).
