Abstract

The extent of voluntary accommodation was investigated behaviorally in two young rhesus monkeys and an adult human using a modified minus-lens technique. Specifically, contrast sensitivity for a high spatial frequency grating was determined as a function of spectacle lens power. Accommodative amplitudes derived from contrast sensitivity vs lens power functions indicate that young monkeys have at least 17 to 18 D of voluntary accommodation and that the accommodative amplitudes of monkeys are larger than those of equivalent-aged humans.

摘要

使用改良的负透镜技术，对两只幼年恒河猴和一名成年人的自主调节程度进行了行为学研究。具体而言，将高空间频率光栅的对比敏感度确定为眼镜镜片屈光度的函数。从对比敏感度与镜片屈光度函数得出的调节幅度表明，幼年猴子至少有17至18 D的自主调节能力，且猴子的调节幅度大于同龄人类。
