“…The SNR describes the ratio between two perceptual elements: the amount of discriminable light reaching the eye and the perceived noise. The SNR of a given device can determine the image resolution in low light; the higher the SNR, the better the ability of the device to provide good contrast between objects in low-light conditions (Borissova & Mustakerov, 2009; Higginbotham, 2006; Riegler, Whiteley, Task, & Schueren, 1991). It is well known that NVG resolution performance deteriorates with diminishing light level.…”

The technology underlying night vision goggles (NVGs) enhances human ability to operate in dark and low-light conditions. However, NVG-aided vision is limited relative to daylight human vision and may entail risks. This review focuses on NVGs with image intensifier technology and explores the impact of their use on human performance. The review covers technology and device characteristics (image quality and field of view), physical configuration (ocular configuration, NVG weight, and forward center of gravity), and contextual and environmental factors (mission and task aspects, lighting, weather, and terrain). The key human factors in NVG use are visual and cognitive performance (visual acuity and contrast sensitivity, stereopsis and depth perception, distance and size estimation, spatial orientation, and situation awareness), and physical and physiological aspects (neck strain and injuries, and headaches). Understanding technology and contextual factors and their influence on human factors is critical to improving performance and safety with NVGs. Technology and device improvements, along with appropriate mission planning and training, play a critical role in aided night vision performance. INTroDuCTIoN Vision is the most dominant perceptual sense and requires adequate lighting to be effective. Yet there is often a need to operate in inadequate lighting circumstances. Many military missions and tasks are performed in poor light conditions and in the dark because it affords better concealment and surprise. In addition, numerous civilian operations and occupations take place in poor lighting conditions: search and rescue, law enforcement (police, border control, surveillance, etc.), hunting, wildlife observation, and many more. In most of those circumstances, people aim to perform in poor light conditions as well as they would in the daytime. However, although humans have developed exceptional day vision, they nevertheless have poor night vision. There is a real need, therefore, for technologies to enhance vision in low-light circumstances.
