| Abstract: This study examined the incidence of neckwear tightness among a group of 94 white-collar working men and the effect of a tight business-shirt collar and tie on the visual performance of 22 male subjects. Of the white-collar men measured, 67% were found to be wearing neckwear that was tighter than their neck circumference. The visual discrimination of the 22 subjects was evaluated using a critical flicker frequency (CFF) test. Results of the CFF test indicated that tight neckwear significantly decreased the visual performance of the subjects and that visual performance did not improve immediately when tight neckwear was removed. -- Langan, L.M. and Watkins, S.M.
