How can you train yourself to view these images
Here are a few tips and tricks that can teach you how to do it properly. The good news is, once you have successfully trained yourself to look at a stereogram, it will be that much easier from then on.
1. Start by putting your face up close to the printed stereogram or the digital screen with which you’re viewing it. Hold it horizontally and look through the image as if it weren’t right in front of you.
2. Then move the stereogram slowly away from your eyes. This is the point at which your eyes will try to do what they do naturally – readjust focus. Do not let them. Continue to look through the image as you move it away from you. It may take a couple of tries to get this to work.
3. When you’re confident that your eyes can continue to look through the stereogram, move the image back and forth until the patterns begin to overlap. You should be able to see the beginnings of a blurry three-dimensional picture.
4. Give your eyes a little while to adjust. Once the image snaps into place, you should be able to see a sharp three-dimensional picture.
