Which term describes the simultaneous inward movement of both eyes toward each other to maintain 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).
