True or False: Both eyes must remain open during the entire focusing procedure for night vision goggles.

Keeping both eyes open during the entire focusing procedure for night vision goggles is beneficial for several reasons. First and foremost, this practice helps to maintain a natural field of vision, enabling better depth perception and spatial awareness in low-light environments. Closing one eye can limit peripheral vision, making it more difficult to identify objects or movement outside the narrow view of the NVGs.

Using both eyes also reduces eye strain, as it allows for natural binocular vision, which is advantageous in maintaining clarity and comfort while using these specialized devices. Moreover, when both eyes are used, it can enhance overall situational awareness, which is crucial in many operational scenarios where night vision goggles are employed. Therefore, keeping both eyes open is an essential part of effectively utilizing night vision goggles for optimal performance.
