The performance and comfort of aircrew using stereoscopic displays viewed at a near distance over long periods of time are now important operational factors to consider with the introduction of aerial refueling tankers using remote vision system technology. Due to concern that the current U.S. Air Force vision standards and test procedures may not be adequate for accurately identifying aircrew medically fit to operate this new technology for long mission durations, we investigated performance with the use of a simulated remote vision system and the ability of different vision tests to predict performance and reported discomfort. The results showed that the use of stereoscopic cameras generally improved performance but that individuals with poorer vision test scores performed more poorly and reported greater levels of discomfort. In general, newly developed computer-based vision tests were more predictive of both performance and reported discomfort than standard optometric tests.
