The Effect of Modified Spectacles on the Field of View of the Helmet Display Unit of the Integrated Helmet and Display Sighting System,

Abstract

A study was conducted to establish the effect of wearing modified aviator spectacles, either for laser protection or refractive error correction, on the field-of-view available with the Helmet Display Unit (HDU) of the Integrated Helmet and Display Sighting System (IHADSS). The determining factors of the available field were found to be helmet fit, eye fixation direction, and eye relief distance. The study concluded that when these factors are optimized, the wearing of the modified spectacles does not result in a loss of field-of-view.
