Abstract

This study evaluated peripheral vision through the M43 protective mask currently worn by aviators in the AH-64 Apache helicopter. A Humphrey Visual Field Analyzer was used to measure the sensitivity of a subject's visual field with and without the mask. The results were analyzed using Dicon's Fieldview software. The monocular visual field was reduced for each eye when wearing the mask, especially superiorly and nasally. The overall size of the visual field was not reduced when both eyes were open; however, the quality of the visual field was reduced. The area of binocular vision (central binocular vision fusion field subserving stereopsis) was restricted to the central 30 degrees.
