Abstract:

The present study examines the effects of wearing bifocal glasses and interpolated rest periods on the performance of 40- to 50-year-old subjects on a radar monitoring task. The visual display was designed to resemble an air traffic control radar display containing computer-generated alphanumeric symbols. ; Forty men and women were divided into four equal-sized groups, with each group consisting of one of the four possible combinations of bifocal/no-bifocal and rest/no-rest conditions. All subjects were tested over a 2-hour session. Rest periods (a 5-minute break every 30 minutes) significantly reduced the performance decrement of 40- to 50-year-old subjects, bringing performance to a level approximating that of 18- to 29-year-old subjects without rest periods. The wearing of bifocal glasses did not contribute to visual strain or somatic discomfort.
