Abstract:

The study discussed in this report is exploratory. It was undertaken to 1 determine the effects which age, lighting and the duration of near vision tasks have on visual accommodation and 2 obtain vision data which could be applied to improve aircrew utilization and crew station design. The results indicated the ability to focus the eyes at infinity following the performance of near vision tasks decreases with age and eye focusing time is related to the duration of the near vision task, and with some exceptions, increases with increase in near vision task time. Further study, utilizing larger sample sizes, is required to verify these preliminary conclusions and expand their usefulness to crew station designers. Author
