This is due to the distribution of the photoreceptors in the retina (back of the eye). There are two types of receptors, cones and rods. Cones have color vision, but low sensitivity to light levels, whereas rods only "see" black and white, but are very sensitive to changes in light levels.

The Short Answer

This is due to the distribution of the photoreceptors in the retina (back of the eye). There are two types of receptors, cones and rods. Cones have color vision, but low sensitivity to light levels, whereas rods only "see" black and white, but are very sensitive to changes in light levels. Now look at this image: _URL_0_ It maps the receptor distribution along the retina. The fovea is the center. Notice how in the fovea (labelled as zero degrees), cones dominate while rods are non-existent – but rods are more prominent in the periphery. Hence the better ability to distinguish light in the peripheral vision.
