THE EFFECTS OF INTERRUPTION OF DARK ADAPTATION ON PERFORMANCE OF TWO MILITARY TASKS AT NIGHT

Abstract

To determine how interruption of dark adaptation (by using an intensifier) affected performance of military tasks with unaided vision at night, two series of studies were conducted. In one series, subjects walked parallel to a guideline, keeping as far as possible to the right; in the other series, subjects fired the M14 rifle at silhouette targets. Interruption of dark adaptation with a simulated monocular intensifier in the shooting eye or both eyes just before the task was begun affected the horizontal distance at which the guideline was followed. A readaptation interval of two to three minutes after interruption of dark adaptation by a binocular intensifier was related to performance under dark-adapted vision.
