Visual discomfort while watching stereoscopic three-dimensional movies at the cinema

Visual discomfort while watching stereoscopic three-dimensional movies at the cinema

".... the analysis of the symptoms experienced by S3D movie spectators based on retrospective visual comfort assessments, showed a higher level of external symptoms (eye burning, eye ache, tearing, etc.) when compared to the internal ones that are typically more perceptual (blurred vision, double vision, headache, etc.). Furthermore, spectators of S3D movies reported statistically higher symptoms when compared to 2D spectators....."

Comments: In a way this does not make sense. Eye burning, aching, tearing should be present as often monocularly as binocularly. If S3D movies cause more symptoms than those viewed in 2D....the fact that they are 3D (needing a certain level to binocular skills) means that 3D induced symptoms must have a fairly great binocular component.
