Extended Use of Night Vision Goggles: An Evaluation of Comfort for Monocular and Biocular Configurations.

Abstract

Forty-four military participants were tested in a field experiment to compare the relative discomfort experienced when monocular versus biocular night vision goggles (NVGs) were worn for an extended period of time. Participants traversed wooded terrain to reach various stations where they performed a variety of military and field craft tasks. The total test time was 4 hours. The participants rated their psychological and physiological feelings of discomfort at the completion of the test and again the following evening. Objective measures of NVG optical adjustments were also recorded. The participants who wore the biocular goggle reported a higher incidence of tight neck muscles than did the participants who wore the monocular goggle. However, no other significant differences in discomfort were found that could be attributed to the ocular configuration of the goggles. All participants complained about discomfort from the head harness.
