ELI5: Explain Like I'm 5

3D film

3D movies are movies that are shown on the big screen in a special way so that you get the feeling you are right there in the middle of all the action! The 3D movie experience uses special glasses with different colored lenses. When you put on the glasses you can see both of the images in front of you, one for each eye, at the same time. Your brain then combines the two slightly different images into one image that looks 3D. 3D movies use these glasses to create the feeling that things are flying at you on the screen or that the people on the screen are almost reaching out and touching you.
