Eyes have a natural version of night vision. To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be unchanging and programmed for specific tasks actively adapt to different light conditions, say the scientists who made the discovery. Source 3x.
I have always been able to see better at times under low light conditions that bright light at times. I wear tinted glasses due to a light sensitivity I have. I have found that my Blue eyes work differently than some others. I can at times walk around in the total dark easier than others too.
