Study of the Effectiveness of Glasses, Sun, N-1, Contract Number NXsX 66844 M and S Research Project Number X-542 (Av-282-p),

Abstract

Thirty-two subjects were given training on the Hecht-Shlaer Adaptometer for one week and, on the basis of average threshold, divided into three groups. For the next three weeks, all subjects were tested each morning and then transported to Onslow Beach. During this period, one group had maximum protection from the sun by wearing dark-adaptor goggles; another group was issued sunglasses, N-1; the third group had no protection for their eyes. Average thresholds for each group were computed and compared. No significant differences were found between any of the groups. Possible reasons for the apparent discrepancy between these results and those of other investigators are outlined. (Author)
