Medicine: Dark Eyes

Russian scientists claim that man can increase his ability to see in the dark by 40 to 50%. They also claim that he can shorten the period of eye adaptation to darkness from half an hour (the usual time) to six minutes. Three Russians outlined their principles last week in War Medicine, but did not tell whether the Red Army uses them, or how. Said they:

>”Weak excitations of the organs of sense of hearing, taste or smell enhance the sensitivity of other sense organs, including those of sight, whereas strong excitations have the opposite effect.”

>Sensitivity of the eye, like that of other sense organs, decreases with distention of the viscera. “It is important in responsible reconnaissance operations that the visceral organs of the abdomen and the pelvis should not be overcongested.”
