Richard Gregory suggested that, with lack of peripheral information, eye movements which correct movements due to muscle fatigue are wrongly interpreted as movement of the perceived light. [3] The amplitude of the movements is also undefined. Individual observers set their own frames of reference to judge amplitude (and possibly direction).
