    Listing's law is related to ocular movements, not physics or lens design.

    Best regards,

    Listings law ......................

    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.
