By contrast, dogs have what is called an area centralis: a broad central region with fewer receptors than a fovea, but more than in peripheral parts of the eye.

In Afghans and retrievers, for instance, the area centralis is less pronounced, and the photoreceptors of the retina are more dense along a horizontal band spanning the middle of the eye.

Rutherford, Chadwick, and Ellis affirmed this: "The superior efficiency of an experienced observer appears to be due to greater concentration, to control spontaneous movements of the eye, and to practice using external portions of the retina, thereby avoiding the insensitive fovea-centralis."
