Question

   Have you seen Axater(《阿凡达》）？ It’s a popular   3D movie,and you may have to wear 3D glasses to see  it. The 3D glasses make the pictures from the movie look   as if they are coming straight at you.

  More and more 3D movies are coming to theaters. Some people say 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies more exciting. However,people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

  When we look at an object,each eye sees it at a different angle. Our eyes send the two pictures to our brain,and the brain puts them together. 3D technology uses two film projectors (放映机）. One projects a left  eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So,when we are watching a 3D movie,our brain can’t put together the images sent to our eyes.  The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy or have headaches. A famous eye doctor said if your eyes can’t focus on the same object at once,you will have some trouble watching 3D movies.
