DESIGN:\nProspective interventional observational case series. PARTICIPANTS: Ten\nhealthy Japanese male volunteers (mean age, 39.3+/-2 years [range,\n36-43]) with a best distance corrected visual acuity (VA) of >20/20 who\nperformed near work for 7 hours were included in the study. MAIN\nOUTCOME MEASURES: The differences of subjective and objective\naccommodations, near acuity, and pupil diameters were compared and\nstudied in 2 experimental settings with and without periocular warming.\nMETHODS: Two experiments were performed on each subject on 2 different\ndays. In one experiment, the subjects wore an eye mask and closed their\neyelids for 10 minutes after 7 hours of VDT work (lid closure [LC]\ngroup). In the other experiment, the subjects applied warming sheets\n(WSs) to their eyelids and the periocular region and wore masks for 10\nminutes again after 7 hours of VDT work (WS group). Visual display\nterminal work was performed under the same settings on both days.\nSubjective and objective accommodations, near vision, and pupil\ndiameters were measured immediately before and immediately after the\nresting or warming procedure and again 90 minutes after the resting or\nwarming procedures. RESULTS: Fifty percent of eyes had an increase in\nthe accommodation amplitude of at least 0.5 diopters immediately after\napplication of the WSs. Forty percent of eyes still maintained the\naccommodation amplitude level at 90 minutes. The mean near logarithm of\nthe minimum angle of resolution VA immediately after application of WSs\nand at 90 minutes significantly improved relative to the near acuity\nvalues after simple eyelid closure. CONCLUSION: Periocular warming was\nfound to be associated with increases in subjective and objective\naccommodations, with a concomitant improvement in near VA. Periocular\nwarming with disposable WSs is a simple and effective method of\nincreasing near work-related ergonomy.
