Abstract

Watching 3D on TV bombards the eyes and brain with a succession of flashing images that appear for a fraction of a second. This technology puts potential health risks such as visual fatigue, motion sickness, lingering depth perception problems, disorientation and decreased postural stability, especially children and teenagers may be more susceptible to health issues associated with viewing in 3D. This study performed the visual fatigue assessment of watching 3D on TV in teenagers (age: 18.81 ± 0.53 years) by electroencephalogram (EEG) for brain waves and subjective evaluation. A total of 27 subjects including male and female were considered. The Biopac system’s Acqknowledge program was used as a physiological workstation. The significant (<i>p</i> < 0.05) increase in the beta frequency was observed after watching 3D visuals. This result supported by the subjective evaluation; which shows that the amount of 3D visual fatigue was greater than that of 2D.
