At night, what strategy can improve overall visibility?

Scanning actively with your eyes is an effective strategy for improving overall visibility at night. When visibility is limited, the ability to actively scan the environment helps to detect changes, movement, and potential hazards more effectively. This strategy allows the eyes to pick up on any available light, such as starlight or moonlight, and to adjust to contrasts in shadows and illuminated areas.

Active scanning keeps the eyes engaged and responsive to the surrounding environment, enhancing awareness and allowing for better detection of objects and persons that may not be immediately apparent in the dark. Such movement promotes a broader view of the area, ensuring that nothing is overlooked, which is crucial in low-visibility conditions.

Other strategies, while potentially useful in different contexts, do not directly enhance visibility as effectively. Using brighter light sources could compromise night vision capabilities and create glare, reducing situational awareness. Limiting movement and staying still in a dark area can make one less aware of their surroundings, as stationary observation can lead to missing critical cues in a dynamic environment.
