In simple terms, the word “cybersickness” has been used to refer to “visually induced motion sickness” (Gallagher and Ferre. Multisens Res 31(7):645–674, 2018). Much of the literature on this topic discusses it in the context of VR (virtual reality) environments (such as in video gaming), but in clinical practice, the more commonly encountered situation is that of patients who experience uncomfortable sensations (such as dizziness and nausea) associated with “screen time” (movies or television, working on a computer, etc.). There is relatively little literature on this topic. Much of the literature about cybersickness extrapolates from previous research on constitutional motion sensitivity (“motion sickness”). There is no widely accepted method for studying cybersickness, and proposals regarding the underlying mechanism of the disease have remained conjectural. Practically, most patients either practice trigger avoidance or “break up” the offending visual exposure into smaller, more manageable chunks. We have also seen patients counseled by neuro-optometrists to attempt strategies such as limiting the field of view (in other words, avoid very wide-screen monitors), reduce screen motion where possible, or try a variety of visual filters or lens tints. In patients with very prominent gastrointestinal symptoms, antinausea medication may be helpful, though does not eliminate the problem.
