This trial was conducted to determine if the prescription (R/x) Ballistic Eye Wear (BEW) solution was acceptable for employment by soldiers performing mission essential tasks operating throughout the 24-hour continuum. Nine regular force infantry soldiers from the 3rd Battalion Princess Patricia’s Canadian Light Infantry Regiment, Edmonton, Alberta, participated in this trial. They wore the R/x inserts while performing various tasks. Four participants from NDHQ also wore and evaluated the R/x inserts. This report presents the data from the 3rd Battalion Princess Patricia’s Canadian Light Infantry Regiment participants. The R/x insert was evaluated on the following criteria: visual acuity, field of view, special features, fit, compatibility with activities and equipment, environmental suitability, care, protection, adjustment, visual characteristics, comfort, and overall ratings. Data collection included questionnaires, performance measures, and HF observer assessments. Overall the soldiers found the R/x insert to be acceptable for all criteria. The main concern regarding the R/x insert was its durability. During the trial a few of the inserts broke at the attachment point to the BEW nose bridge. The soldiers stated that they found the R/x solution to be acceptable except for this durability issue. It is recommended that this attachment mechanism be made more durable.
