People with Vision Problems The illusion of watching movies in three dimensions is not calibrated exactly the same way in the brain than the eyes. If they have a problem, wasted a great effort will be made after the brain, a disparity that can lead to headaches in people with a visual impairment, according to U.S. researchers.

3D movies may cause headaches for people with vision problems, even as minor as a slight muscle imbalance, according to Michael Rosenberg, professor of Ophthalmology at the University of Chicago Feinberg (United States). Rosenberg, has warned that in a 3D movie, these people face a new sensory experience that involves them “greater mental effort, which makes it easier to have a headache.”

“There are many young people suffering vision problems, such as small muscle imbalances, which in normal circumstances, the brain handles naturally,” said the professor.

Dr. John Hagn, ophthalmologist in Kansas City, Missouri (USA), has stated, in this connection that some people who do not have normal depth perception can not perceive the 3D image. In particular, people with eye muscle problems, in whom the eyes are not facing the same direction, have trouble processing such images.

Another professor of Ophthalmology and Neurology at the University of Rochester Medical Center, New York (USA), Deborah Friedman, explained that under normal circumstances, each eye sees things from a slightly different angle and, where 3D images are processed by the brain, it creates a sense of depth.

Thus, the illusion of watching a movie in three dimensions is not calibrated exactly the same way the eyes in the brain. If the eyes have a problem, then it really wasted a great effort will be made after the brain, said the expert, who says that this disparity “gives headache to some people.”

Although no studies to record the frequency with which headaches occur when 3D movies, according to spokesman Rick Heineman RealD, a provider of 3D equipment for theaters, headaches and nausea that generate these images was the main reason that this technology does not come off the ground at the time.
