So how do 3D glasses work? Well basically, your eyes have to see slightly different images. In the real world, since your eyes are spaced apart, each eye gets a different view, therefore the brain puts the two pictures together to make a 3D image. Binocular vision; since our eyes are 2 inches apart, there are two different views. Have you ever looked at a 3D movie without glasses and see fuzziness? Well that's because they took original picture and shifted it like what our brain does. But the shifted image is only made of red and blue. So what the glasses do is the color filters separate the two images and each one enters a different eye. Then your brain the two images back together so it looks like its happening right in front of you. So go buy some 3D glasses.
