Which term refers to the focusing of the eyes outward?

The term that refers to the focusing of the eyes outward is divergence. When the eyes diverge, they rotate away from one another, allowing for better focus on objects that are further away. This is an important physiological response for distance vision, where the visual system needs to adjust to maintain clarity of the image being focused on.

Divergence contrasts with convergence, which involves the eyes moving towards each other to focus on closer objects. Aniseikonia and presbyopia relate to visual distortions and age-related changes in vision, respectively, but do not describe the movement of the eyes in relation to focusing distance.
