He human eye is poorly suited to night vision, suffering impairments in seeing the environment in low light situations.

Explanation:

In the eyes are the rods, the neurons responsible for the night vision. In total darkness, there is a need for at least 45 minutes to get the best vision, because the human eye is poorly adapted to night vision and is deficient in seeing in the dark. In the retina of the human eye there are two distinct regions, one responds by the central vision, the macula, and another peripheral vision.

Inside the macula, a region called fovea consists only of cones, which are neurons responsible for maximum vision. The cones do not work in low light conditions. However, around the fovea, there is a mixture of conese rods. This blend allows an intermediate view, which guarantees the ability to see in the penumbra.
