What is an optimal practice for using NVGs to enhance operational effectiveness?

Taking regular breaks to rest the eyes is an optimal practice for using night vision goggles (NVGs) as it helps reduce eye strain and fatigue, which can impair vision and operational effectiveness over time. NVGs enhance vision in low-light conditions by amplifying available light, but prolonged use can lead to discomfort, temporary vision disturbances, and decreased night vision performance. By incorporating breaks, users can allow their eyes to recover, maintain focus, and retain the ability to adapt to changing light conditions while wearing NVGs.

In comparison, using NVGs in bright light conditions can lead to damage and reduced functionality of the devices; engaging in vigorous physical exercise before using NVGs may lead to increased heart rate and sweat, which could cause discomfort or impact concentration; using NVGs only in open terrain might limit the adaptability of the gear, as NVGs are designed to be effective in a variety of environments, including more complex terrain.
