3D movies may cause headaches and other diseases

It is true that the current feeling great science fiction 'Avatar' is breaking every record that put him ahead. But the striking element of 3D in this film (and others) can cause very undesirable side effects.

Many viewers complained that 'Avatar' and other films in 3D format they have caused headaches, nausea, blurred vision and other symptoms of eye diseases, reports the New York Times.

Normally, when an object approaches a person, the eyes can respond in two ways. One is that the eyes converge, or rotate inward (a clear example is when one extends his arm and index finger on his nose). At the same time, while the object is approaching, the eyes focus and maintain a clear picture of him as they are changing the ways of the lens, a process called visual accommodation.
But a 3D object flying "off the screen, causes a sensory conflict. The eyes rotate inward to follow, but must also stay focused on the surface of the screen. Thus, they accommodate and converge without a disconnection occurs two natural processes in the course of a long movie, you can end up being stressful.

So far, there is no proven way to prevent this, however there are some tricks that movie-goers who have already spent several hours watching film 'Avatar' recommendations: avoid displaying this is out of focus parts of the scenes, which sounds a lot easier than it really is.
