Computer vision syndrome (CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye's muscles being unable to recover from the constant tension required to maintain focus on a close object.
The symptoms of vestibulocerebellar syndrome vary among patients but are typically a unique combination of ocular abnormalities including nystagmus, poor or absent smooth pursuit (ability of the eyes to follow a moving object), strabismus (misalignment of the eyes), diplopia (double vision), oscillopsia (the sensation that stationary objects in the visual field are oscillating) and abnormal ...
Seeing 3D movies can increase rating of symptoms of nausea, oculomotor and disorientation, especially in women with susceptible visual-vestibular system.This is caused by a “disagreement” between the vestibular system and the visual input, causing that the body interprets it is moving, creating a contradiction with the vestibular system.

The cause of the syndrome is unclear. [3] The underlying mechanism is believed to involve excessive excitability of neurons in the right lingual gyrus and left anterior lobe of the cerebellum. Another hypothesis proposes that visual snow syndrome could be a type of thalamocortical dysrhythmia and may involve the thalamic reticular nucleus (TRN ...
