What is the focusing of the eyes inward called?

Focusing the eyes inward is referred to as convergence. This term describes the action of both eyes turning toward each other to maintain a single focus on an object that is closer to the viewer. Convergence is a critical aspect of depth perception and allows for the ability to see objects clearly and relationally in three-dimensional space.

In the context of eye function, when a person shifts their gaze from a distant object to something closer, the eyes must work together and converge to ensure that the visual information aligns correctly in the brain for clear interpretation. This process involves the coordinated action of the eye muscles, which adjust to bring the images from both eyes into focus.

This physiological adjustment is vital for tasks such as reading, where items are typically at a closer proximity, demonstrating how convergence is essential for maintaining visual clarity and comfort during such activities.
