The Accommodative Status in the Dark of U.S. Navy Fighter Pilots.

Pagination or Media Count:
Visual accommodation of 172 naval aviators in the dark was measured and compared to their most recent night carrier landing scores and the average distance at which an adversary aircraft was first sighted during air combat maneuver training. No significant correlations were found between the accommodation measures and either measure of operational performance. Reasons for this result are discussed. Accommodation measures in the aviator sample in the dark are compared to measures made in samples of college students reported in the literature. The aviator sample is significantly less myopic than the student sample. For example, only 6 of the students have as little myopia as the average naval aviator. This dramatic difference in accommodation could result from either training or some set of selection factors. Possible reasons for this finding and its significance for the Navy are discussed.
