Abstract: Luminance thresholds for the visual resolution of various widths of alternating light and dark lines were determined at various times during recovery from different durations of light adaptation. Increasing duration of preadaptation from one second to five minutes raises the initial dark adaptation thresholds and decreases the speed of the recovery process. The level of visual acuity determines the range of luminance covered by the dark adaptation curves.
