3DTV Report Finds Discomfort a (Minor) Issue

3DTV never really got off the ground, and one of the reasons often heard from consumers for their lack of interest was that 3DTV glasses caused discomfort.

A new report out of Newcastle University in the U.K. seems to back up that notion … but only to a point.

The study had more than 430 viewers watch the movie Toy Story in both 2D and 3D, and found that 14% experienced headaches and eyestrain while watching a 3D film with glasses. However, about 8% who watched the film in 2D but wore the 3D glasses all the same also reported adverse affects, suggesting the glasses, not the content are the cause.

Women were more slightly likely than men to experience discomfort, and the report could find no correlation between pre-existing eye conditions and discomfort

“… Anecdotal evidence and the manufacturers’ own safety information has suggested for some time that stereoscopic 3D may have negative impacts on viewers, with symptoms such as headache, eyestrain, dizziness and impaired motor coordination,” the report reads. “There is considerable evidence that visual symptoms such as eyestrain or blurred vision can be caused by the disruption of the natural relationship between binocular convergence and accommodation.”
