If we assume that the eye is a solid, in terms of mechanics its position relative to the head depends on six parameters, at the maximum. This is because it has six degrees of freedom. Actually, the number would be reduced to three if a point Q, fixed in the eye, remained fixed relative to the head, for every eye movement. Movements of the eye would then be reduced to rotations around the point Q, called the center of rotation.
