Convergence

The term for when a patient's eyes move inward to focus at near is known as convergence. Convergence is a natural process that occurs when the brain and eyes work together to allow both eyes to focus on close objects. This inward movement enables adequate alignment of the visual axes in order to obtain a single, clear image from both eyes, which is essential for depth perception and seeing smaller details clearly.

This physiological response is critical for proper near vision as it helps maintain binocular vision, where both eyes work together effectively. Understanding convergence is vital for opticians and eye care professionals as it relates directly to the assessment of a patient's ability to see clearly at varied distances, and can lead to diagnosis and management of various vision disorders.
