What impact does ocular health have on NVG efficiency?

Maintaining good ocular health is crucial for the effective use of night vision goggles (NVGs). Poor ocular health can significantly impair an individual's ability to see clearly, which directly affects the efficiency of NVGs. When a person has vision problems, such as nearsightedness, farsightedness, or other eye conditions, these issues can hinder the proper functioning of NVGs. For instance, if the eyes are not able to focus properly, the enhanced low-light vision provided by the NVGs may not be utilized effectively, leading to a less clear and effective visual experience. This can be particularly unsafe in operational environments where clear sight and situational awareness are critical. So, a healthy visual system is essential to maximize the potential benefits offered by NVGs.
