Variation of the resting potential caused by eye movements was analyzed by applying a battery model to the eyeball. A formula that gives the potential between the inner canthus and the outer canthus of the eye was derived on the basis of the electric theory in electromagnetics, on the assumption that the eyeball was floating in a homogeneous conductor. The variations of the resting potentials were represented using the distance from the center of the eyeball to the potential detecting position and the deflection angle of the position with respect to the optical axis of the eyeball. To verify the validity of the formula, the variation of the resting potential caused by the various amplitudes of bilaterally symmetrical eye movements were measured. The calculated results were found to be in good agreement with the experimental ones.
