Hering was the first to propose a mechanism that could account this phenomenon, in the form of a law that bears his name (Hering, 1868). WitrynaThe law also states that apparent monocular eye movements are actually the mathematical summation of conjugate version and vergence eye movements. The law was put forward by Ewald Hering in the 19th century, though the underlying principles of the law date back to Alhacen's Book of Optics (1021).

Hering's law of visual direction describes the perceived visual direction of a point relative to an observer.

Thus comes the question of where a point is perceived, relative to the observer, when seen with either eye alone or binocularly. In 1879 Ewald Hering stated …
