TASK-PERFORMANCE WITH VISUAL-ACUITY WHILE WEARING A RESPIRATOR MASK

Forty-six subjects were required to perform a console-monitoring and t wo hand-eye coordination tasks while wearing masks with lenses clouded to give seven levels of visual acuity. The console-monitoring task pe rformance was found to be the most sensitive to visual acuity, followe d by the random hand-eye coordination task. These results can be used to help predict performance degradation when lenses become clouded due to condensation or particulate deposition.
