Report No: DOT/FAA/AM-71/27
Title and Subtitle: Color defective vision and the recognition of aviation color signal light flashes
Report Date: June 1971
Authors: Lewis MF, Steen JA
Abstract: A previous study reported on the efficiency with which various tests of color defective vision can predict performance during daylight conditions on a practical test of ability to discriminate aviation signal red, white, and green. In the current study, subgroups of the subjects used in the previous investigation were tested with the signal light gun at night. Comparisons of the efficiency of each of seven tests of color defective vision in predicting performance under day and night conditions are reported.
Key Words: Color Vision, Signal Lights, Night Flight, Visual acuity
