It is proposed that dark adaptation following a moderate pigment bleach may nearly as well be carried out (and more conveniently) under low room lighting conditions as in complete darkness. To test this idea, dark adaptation curves were determined either immediately after the termination of a 3 min, 4.1 log td white pre-exposure field, or following 10 or 15 min of additional exposure to one of three low-level photopic (2.9, 2.4, 1.8 log td) backgrounds of white light. Dark thresholds measured after the additional exposure fell rapidly and reached the rod plateau of the normal dark adaptation curve with a maximal delay of 1.5 min (for the 10 min backgrounds) or 6.5 min (for the 15 min backgrounds). For the time to be spent in the dark, this meant a savings of 8.5 min. At smaller delays savings were even greater. The difference between savings and delay indicates whether or not an interposed background is feasible.
有人提出，在中等程度的色素漂白后，暗适应在低室内光照条件下几乎可以同样好地进行（且更方便），就如同在完全黑暗中一样。为了验证这一想法，在3分钟、4.1对数td白色预曝光场结束后立即测定暗适应曲线，或者在额外暴露于三种低水平明视觉（2.9、2.4、1.8对数td）白光背景之一10或15分钟后测定暗适应曲线。额外暴露后测得的暗阈值迅速下降，并在正常暗适应曲线的视杆细胞平台期达到最大值，最大延迟为1.5分钟（对于10分钟背景）或6.5分钟（对于15分钟背景）。对于在黑暗中花费的时间而言，这意味着节省了8.5分钟。在较小的延迟情况下，节省的时间甚至更多。节省时间与延迟之间的差异表明插入背景是否可行。
