Monocular accommodation responses to stimuli at vergences from 0 to -4.5 D (i.e. effective object-eye distances from infinity to 22 cm) were measured objectively using artificial pupils of 0.5, 0.75, 1.0 and 3.0 mm diameters and a constant retinal illuminance of 7000 td. The slopes of the response/stimulus curves for the 0.75, 1.0 and 3.0 mm pupils agree with those reported previously. The 0.5 mm pupil produced open-loop accommodation, no systematic change in accommodation being observed as the stimulus vergence was varied. However, the response drifted considerably with this pupil diameter.
使用直径为0.5、0.75、1.0和3.0毫米的人工瞳孔以及7000 td的恒定视网膜照度，客观测量了单眼在0至-4.5 D的聚散度（即有效物眼距离从无穷远到22厘米）下对刺激的调节反应。0.75、1.0和3.0毫米瞳孔的反应/刺激曲线斜率与先前报道的一致。0.5毫米瞳孔产生开环调节，随着刺激聚散度的变化，未观察到调节的系统性变化。然而，使用该瞳孔直径时，反应有相当大的漂移。
