IPNVG Fixed-Focus Diopter Study

Abstract

Integrated Panoramic Night Vision Goggles (IPNVGs) are the prototype night vision goggles (NVGs) and may be the next generation of NVGs. The AN/AVS-9 (F-4949) NVGs, worn by Air Force aircrews, have continuously adjustable eyepieces (from +2.0 diopters (D) to -6.0 D). Unlike the F-4949s, IPNVGs have a fixed-focus eyepiece at -1.0 D. However, previous research has shown that some operators are very insistent that their visual acuity is impaired if they do not have eyepiece settings on the order -2.0 D or more, where they are currently setting their NVGs. The proposed solution is to provide snap-on lenses to the IPNVGs in order to obtain a selection of settings. The purpose of this study is to determine if NVGs with this discrete number (two) of snap-on lenses are acceptable or if additional lenses are required.
