We compared the resting (dark) focus of accommodation before and after adapting to accommodative stimuli placed nearer or farther from an initial baseline resting focus. Short-term monocular adaptation (less than 2 min) did not result in consistent after-effects that were correlated with the adaptation stimulus. After short-term adaptation, accommodation returned to its resting level in 2-15 s. Long-term monocular adaptation (30 min) to a 6-D near stimulus resulted in a small (0.5-D) average increase in the resting focus of accommodation beyond the normal 2-15-s short-term decay. These observations illustrate a tonic adaptation of accommodation that is small and requires longer durations of adaptation than an analogous adaptation of the fusional vergence system to prism.
我们比较了在适应放置于比初始基线静息焦点更近或更远的调节刺激前后的静息（暗）调节焦点。短期单眼适应（少于2分钟）并未产生与适应刺激相关的一致后效应。短期适应后，调节在2 - 15秒内恢复到其静息水平。对6屈光度近刺激进行长期单眼适应（30分钟）导致调节静息焦点平均小幅增加（0.5屈光度），超出正常的2 - 15秒短期衰减。这些观察结果说明了调节的紧张性适应，其幅度较小，且与融合性聚散系统对棱镜的类似适应相比，需要更长的适应持续时间。
