Optical sliding - PsychonautWiki
Open main menu

Optical sliding can be described as a physical effect which inhibits the coordination and control of a person's eyes by suppressing their ability to keep them still. This results in the eyes continuously moving in a variety of directions combined with the sensation of not being able to stare motionless at any particular point.

The optical condition nystagmus causes sufferers very similar symptoms, although the frequency of movement is generally far greater with nystagmus.

Optical sliding is often accompanied by other coinciding effects such as acuity suppression and double vision. It is most commonly induced under the influence of heavy dosages of dissociative compounds, such as ketamine, PCP, and DXM. However, it can also occur to a lesser extent under the influence of extremely heavy dosages GABAergic depressants.
