Paper Abstract

The wide field of view night vision goggles (WNVG) are the next generation of night vision goggles (NVGs). They have a significantly increased horizontal field of view and a weight similar to the current AN/AVS-9, which only has a 40 degree circular field-of-view (FOV). Due to complicated optics and weight issues, the WNVG will have a fixed-focus eyepiece; this is different from the AN/AVS-9 (Figure 1), which has a continuously adjustable +2.0 to -6.0 diopter (D) range for each eyepiece. Site visits were made to several Special Operations Squadrons to survey aircrew members about the WNVG with a fixed-focus eyepiece and optional clip-on lenses. This paper addresses aircrew acceptance of the use of snap-on/helper lenses in place of continuously adjustable eyepieces.
