Solution
Night vision is enhanced by looking slightly to one side of the object you wish to view.
Here's why:
-
The center of the eye is filled with cones, which are color receptors that work best in bright light.
-
The periphery of the eye, however, is filled with rods, which are more sensitive to light and dark changes, shape and movement and contain the pigment rhodopsin, which improves low-light vision.
-
Therefore, when you look slightly to the side of the object, you are using more rods which improves your night vision.
-
This technique is called "off-center viewing" or "averted vision."
-
So, while it might seem counterintuitive, looking directly at an object in low light can actually make it seem more obscured.
