What is Listing's Law?
Donders law states that the orientation of the eye when looking in a specific direction is always the same. Listing's law specifies what this orientation is. Note the axes (the bars protruding from the eyes) used to rotate from center to various eccentric positions. Listing found that all these axes are confined to a common plane. This plane is called Listing's plane.
