The simultaneous turning in of both eyes that occurs when viewing an approaching object is called convergence. What is the term for the turning outward as the object moves away?

Explanation:
In binocular vision, the eyes adjust their position using vergence movements. Divergence is the outward turning of both eyes as an object moves away, allowing the eyes to stay aligned on a single target. Convergence is the inward turning that occurs when an object approaches, while divergence specifically describes moving outward. Vergence is the general term for these inward or outward eye movements, but the outward case asked for here is divergence. Accommodation, on the other hand, is about changing the lens shape to focus, not the eye’s turning.
