vergence

 [ver´jens]
disjunctive movement of the eyes in opposite directions in adjusting to near or far vision; convergence or divergence.

ver·gence

(ver'jĕnts),
A disjunctive movement of the eyes in which the fixation axes are not parallel, as in convergence or divergence.
[L. vergo, to incline, to turn]

vergence

/ver·gence/ (ver´jens) a disjunctive reciprocal rotation of both eyes so that the axes of fixation are not parallel; the kind of vergence is indicated by a prefix, e.g., convergence, divergence.

vergence

(vûr′jəns)
n.
1. A measure of the convergence or divergence of a pair of light rays, defined as the reciprocal of the distance between a point of reference and the point at which the rays intersect.
2. The inward or outward turning of one or both eyes that occurs when focusing on an object.
