As an electronic device, night vision goggles must be stored in a cool, dry place. While they may not be immediately damaged in the harsh conditions of Guangdong and Guangxi, it will severely impact their lifespan. Night vision goggles are relatively delicate instruments and are generally not shockproof, so avoid dropping them. For those who like to wipe the lens, avoid friction with hard objects, as the lens has an optical coating that is easily scratched. The lens does not need to be disassembled for internal cleaning, and the battery should be removed if the device will not be used for an extended period.
Night vision goggles should never be exposed to strong light. Exposure to strong light can burn out the image intensifier tube. Why? This relates to the principle of night vision goggles. They amplify electrons using a microchannel plate, requiring weak light. Strong light converts and amplifies more photons, resulting in a large current during conversion, which can burn out the image intensifier and render the night vision goggles unusable.
