Why do 3D movies make you wanna puke?

Nothing can ruin a good movie faster than the sudden feeling that you’re about to throw up. You’re picturing it right now aren’t you?

For many, images in 3D look so real, that they mess up the brain’s ability to sort out the signals coming in from the senses, and then trigger that queasy feeling. This is known as cybersickness. For more about that, check out this video

The dizziness, headaches and nausea are a result of the brain receiving conflicting information from the senses while watching a 3D movie.

Here’s what happens…
When very graphic images play out on-screen, the eyes send signals that tell the brain the body is in motion. Yet inside the inner part of the ear, where the movement of fluid is used to sense motion and balance, no change in the body’s position is detected. The eyes tell the brain the body is moving, but the ears say it’s not, and this is a recipe for nausea.

That’s why when watching the epic movie that is Avatar in 3D, you may feel a little queasy…and it hasn’t got anything to do with those weird blue people.
