How many hours can a licensed instructor utilize night vision devices per night?

A licensed instructor can utilize night vision devices for up to four hours per night to ensure effective training while maintaining the health and safety of the instructor and the trainees. This limitation is in place because extended use of night vision equipment can lead to eye strain and fatigue, potentially diminishing the instructor's ability to effectively teach and provide necessary guidance. The four-hour duration strikes a balance between providing adequate training time and avoiding the negative effects associated with prolonged use of such devices. This policy helps to ensure that both the instructors and the trainees can operate safely and efficiently in low-light conditions, maximizing the effectiveness of their training sessions.
