BACKGROUND: The AcuVision 1000 Trainer is an instrument designed to assess and train eye-hand coordination in athletes. Variable environmental conditions are encountered when sports-vision screenings are performed. The effect of these factors on scores attained on sports-vision testing equipment is an important consideration when results for different populations are compared. METHODS: This study investigated the effect of different lighting levels on subject performance. Twenty-five subjects performed three trials at each of three lighting levels (day-light, dim room, and dark. The presentation order of lighting level was counterbalanced and subjects were randomly assigned to the various presentation orders. RESULTS: The results indicate a statistically significant difference in performance at the various levels. High lighting levels decreased scores significantly, whereas there was no significant difference between the two lower levels. CONCLUSIONS: This study emphasizes the effect lighting can have on performance, and illustrates the need to properly control environmental factors through well-defined testing protocols for the use of the AcuVision 1000.
