Experiments were conducted to characterize the distribution of the monocular components of fixation disparity, i.e., ascertain whether or not the fixation disparity measured by nonius alignments is equally divided between the two eyes or has an unequal distribution. Computer generated nonius lines were used to measure the monocular components of the forced vergence fixation disparity curve (FDC) for subjects with normal binocularity. Thirty-three percent of all subjects tested showed unequal distribution of their monocular components. The composite FDC's for subjects with unequal distribution of the monocular components tended to have steeper slopes than those with equally distributed components. It was concluded that equally divided monocular components are not a prerequisite for good binocularity.
进行实验以表征注视差异单眼成分的分布，即确定通过视差仪测量的注视差异在两只眼睛之间是否平均分配或分布不均。使用计算机生成的视差仪线条来测量双眼正常受试者的强迫性聚散注视差异曲线（FDC）的单眼成分。所有测试受试者中有33%表现出其单眼成分分布不均。单眼成分分布不均的受试者的复合FDC曲线斜率往往比单眼成分分布均匀的受试者更陡。得出的结论是，单眼成分平均分配并非良好双眼视觉的先决条件。
