Abstract : A group of 5750 men was tested on the U. S. Navy Radium Plaque Adaptometer by the Medical Research Department, U. S. Submarine Base, New London, Connecticut. Testing rooms, procedures, and personnel requirements which made the program feasible and easily handled in the space of three weeks are described. Of all men tested, 82.5% passed the test. Of those failing a first test, approximately 60% will pass a second. Only 30% of those failing two tests will pass a third administration. Approximately 5% of the population fail the Radium Plaque on three consecutive tests. It is suggested that these men may constitute that section of the population who can be termed night blind. Field performance studies of these individuals are planned. (Author)
