The most important cues to the normal vergence response are retinal disparity, accommodative effort and perceived distance (proximal cue). In the past, proximal cues have been thought to contribute little to the total vergence response but more recent studies have suggested that they play an important role. The relative contributions of the proximal, accommodative and disparity cues to the vergence response were assessed by measuring the effect upon the vergence system when each of these cues were altered. The effect upon the vergence system was measured by the change in 'phoria, the change of fixation disparity and the amount of prism adaptation after 210 s of binocular viewing. The results indicate that the greatest effect of cue disharmony occurred when the proximal and disparity cues were altered. A finding which signifies the importance of the proximal cue to the overall vergence response.
正常聚散反应最重要的线索是视网膜像差、调节力和感知距离（近端线索）。过去，近端线索被认为对总聚散反应贡献不大，但最近的研究表明它们起着重要作用。通过测量当这些线索中的每一个发生改变时对聚散系统的影响，评估了近端、调节和像差线索对聚散反应的相对贡献。通过测量双眼观看210秒后的隐斜变化、注视像差变化和棱镜适应量来评估对聚散系统的影响。结果表明，当近端线索和像差线索发生改变时，线索失调的影响最大。这一发现表明近端线索对整体聚散反应的重要性。
