A four-day field trial was undertaken at CFB Edmonton over the period of June 12 to 16 2006 to evaluate the difference between constant and variable thickness ballistic visors. Twenty infantry soldiers, regular (n=5) and reserve (n=15) force, of various Canadian units were required to undertake a battery of human factors tests while wearing two different visor conditions in a fully balanced repeated measures design. The trial was split into three phases: the clinical testing, trial overview, and scale explanation; dynamic activities; and focus group. Evaluation exercises included an obstacle course, wooded lane course, vehicle course, urban vehicle patrol course, night patrol course, and FIBUA assault. The participants rated visual characteristics, visual acuity, and task acceptability of the visors for each evaluation exercise. Data collection included target detection performance measures, acceptability ratings, preference rankings, and focus group. Overall, a constant thickness ballistic visor was preferred by participants to a variable thickness ballistic visor for the majority of the human factors criteria. Objective target detection performance data showed no differences between the visors. Clothe the Soldier (CTS) Project is recommended to proceed with the requirement for a constant thickness ballistic visor for the integrated ocular and upper face protection.
