Vibrating vision, also known as nystagmus, can be described as the experience of constant, rapid involuntary eye movements in which the eyes shift from left to right in such quick succession that the person's vision begins to vibrate and blur. This can severely impair vision and result in a reduced ability to function and perform basic tasks which necessitate the use of sight.
Vibrating vision is often accompanied and enhanced by other coinciding effects such as stimulation and thought acceleration. It is most commonly induced under the influence of heavy dosages of stimulant compounds, such as MDMA, amphetamine, and 4-FA.
