Vibrating vision
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 one'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.
This effect is most commonly experienced during heavy dosages of stimulants such as MDMA or amphetamine.
