Abstract:
The luminance thresholds were measured following preadaptation to CRT displays, which consisted of a vertical trace line moving horizontally across the screen at 1, 30, or 60 times/sec. The thresholds were determined during different stages of dark adaptation by the identification of the position of a luminous dial pointer. The initial thresholds were relatively low (-2.0 lg mL), and dark adaptation was complete in about 5 min. Viewing CRT displays resulted in a temporary detrimental effect upon the visual efficiency of aircraft personnel and there by impaired their ability to read instrument dials and perceive objects external to the aircraft.
