vergence
Binocular focus adjustment
Vergence refers to the simultaneous movement of both eyes in opposite directions—turning inward (convergence) when focusing on something close, or outward (divergence) when shifting to something distant.
The term appears primarily in ophthalmology and vision science.
More broadly, vergence can describe any turning or inclination toward a point, though this general sense is rare outside technical contexts.
