Problems with Vision Interfere with The 3D Films Enjoyment

And while some do not see the visual effects, other have nausea, experts say…

If we are to believe the data on the number of tickets sold, cinemas, thanks to the latest wave of 3D films, are more filled with visitors than ever. It seems that everybody really enjoy all the visual effects of the latest 3D technology. But in reality everything is not so perfect.

“In every cinema projection there are at least a few people who simply will not notice the typical 3D visual effects, but will feel a slight nausea,” said an American ophthalmologist Dr. Dominick Maino.

Vision problems in the U.S. alone, have 3-9 million people. And all of them cannot enjoy the latest 3D creations like Avatar or Toy Story 3. Research also shows that 56 percent of people between 18 and 38 are suffering from symptoms related to the problem of depth perception.

Mentioned problems are associated with binocular vision. It is the ability that two pictures of one subject, which are created in each eye, unite into a single, three-dimensional perception.

“When the brain merges the two images, we get the 3D effect. Aforementioned 3D marks our ability to judge distance. It is a vitally important feature that enables us to assess how far away are we from, for example, an angry tiger who wishes to eat us for lunch,” say ophthalmologists.

Studies have shown that headaches, blurred vision and dizziness are most common side effects in viewing 3D films, especially in people who have problems with binocular vision.
