The purpose of this study was to determine the effects of illumination color, viewing distance, and turbidity on a visual reading task in a totally dark, flooded environment. The reading task was to read a voltmeter and make a correct oral report of the reading. A total of 180 data points spread over 18 viewing conditions were taken for each subject. Seventeen military officers were used as subjects. Experimental conditions were presented in a random manner to all subjects. A statistical examination of the results showed that white or green illumination is better than red in reducing reading response time. Turbidity levels were significant in affecting both increasing as the Attenuation Coefficient increased. Author
