Helmoholtz argued that the eye moves in accordance with Listing's law to ensure that objects have the same apparent direction despite changes in the point of fixation. Listing's law ensures that the same pattern of image displacements is associated with a given eye movement, independent of the initial point of fixation. His explanation has been extended to the problem of ensuring that objects remain at the same apparent depth, with both direct and indirect fixation. This problem is simplified if disparity is analysed in the region of the frontal plane.
亥姆霍兹认为，眼睛按照利斯廷定律移动，以确保尽管注视点发生变化，物体仍具有相同的视向。利斯廷定律确保相同的图像位移模式与给定的眼球运动相关联，而与初始注视点无关。他的解释已扩展到确保物体在直接和间接注视下保持相同视深度的问题。如果在额平面区域分析视差，这个问题就会简化。
