Audio-visual technological innovation has drastically changed our visual environments. Our visual system receives an overload of visual information in our daily lives. Visual stimuli, especially unsteady video images taken with shaking hands can induce motion sickness and cause nausea and headache as autonomic dysfunctions. We analyzed autonomic functions such as pupillary responses, heart rate, and blood pressure during movie presentations. Sympathetic hyperactivity was observed in the affected subjects. Pupillary responses signify autonomic activities clearly with non-invasive methods. We applied pupillometry for evaluation of stressed subjects and diagnosis of neurological diseases. We observed parasympathetic nervous dysfunction in those subjects. Evaluations of the relationship between visual and autonomic functions could be a potential marker for understanding the visual-autonomic systems.
