The London Olympic Games are coming soon．Chinese sports fans will be able to watch the exciting games in 3-D on CCTV．
When you watch 3-D movies or TV，you have to wear a special pair of glasses．The 3-D glasses make the images look like they are there in the room with you．For example，while a car is running fast towards you on the screen，you are afraid that it will hit you．Yes，it's a 3-D movie．But do you know how they are made？3-D is based on the way the human brain and eyes work．When we look at something，each eye sees it from a different angle（角度）．Our two eyes send the two images to our brain，and the brain puts them together．What you see becomes 3-D．
3-D movies are made using two video cameras at the same time，which creates two different images at different angles．When the movie plays in a cinema，two projectors put the two images on the screen．One projects（投射） a left eye image and the other projects a right eye image．The 3-D glasses help get a different image into each eye of us．
While watching 3-D films，we feel that we are actually in the same environment as the things we're watching．However，it also has its disadvantages．The 3-D glasses make the screen look darker so your eyes are easy to get tired．What's more，people with eye problems may get headaches if they spend too much time watching 3-D movies，because their brains need to work harder to"read"the images．
