proximal convergence

Proximal convergence is the inward movement of the eyes triggered by the perception of an object’s proximity, independent of accommodation or fusional stimuli. It is a reflexive convergence response elicited by the awareness of a nearby target, even in the absence of blur or diplopia cues. Proximal convergence contributes to the overall convergence response, along with accommodative and fusional components, to maintain binocular single vision at near distances.
