The gradual improvement of the eyes' sensitivity after a shift in illumination from light to near darkness.

The process by which the human eye's sensitivity increases in response to marked luminance decreases. If the average luminance on the retina decreases suddenly from daytime photopic levels, a lig [..]

the capacity of the eye ball to acclimate to certain states of low illumination by way of an escalated sensitiveness to light. The majority of this procedure takes half and hour and consists of dilati [..]

Dark Adaptation is the process by which our eyes adjust to darkness after being exposed to light. For example, when we move from a bright, sunny area outside to a relatively dark room inside, it is di [..]

The eyes’ transition to night vision, in order to see faint objects. Dark adaptation is rapid during the first 5 or 10 minutes after you leave a well-lit room, but full adaptation requires at least a half hour — and it can be ruined by a momentary glance at a bright light.

The adjustment of the eyes that occurs over time when one enters a darkened area. This adjustment permits the eye to see better in the dim lighting conditions.

The process by which the eye becomes adapted to a luminance less than about 0.03 candela per square meter (0.01 footlambert). Diffuser: A device used to distribute light from a source. Dimmer: Dimmers can reduce the input power requirements and the rated lumen output levels of in- candescent and fluorescent lights. Fluorescent lights need special d [..]

Adjustment of the eyes under conditions of low Light. The sensitivity of the eye to Light is increased during dark adaptation.

Adjustment of the eyes under conditions of low light. The sensitivity of the eye to light is increased during dark adaptation.

The ability of the human eye to adjust seeing dim objects in the dark.
