Abstract : A procedure for the routine testing of large populations of men in night vision is proposed. Data, obtained in previous experiments, are presented which indicate that the proposed method will yield results satisfactory for the purposes. The method calls for testing at a single relatively high brightness level with consequent spread of the lower 20-25% of the population, who are to be retested before final qualification or disqualification for duties at night is reported. This method, it is believed, will permit more rapid, more reliable, and more satisfactory selection of men with respect to night vision. (Author)
