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.
