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.

vergence

1. Movement of one or both eyes so that the visual axes converge or diverge.
2. The effect caused on a parallel beam of light by a convex (converging) or concave (diverging) lens.
