Magic Eye Difficulties

 So when we were  in class the other day we looked at Magic Eye pictures. I couldn't see any other the pictures so I looked into why I couldn't. I found that being able to see the images has to do with the way our eyes work together. If they do not work together and pulling together in unison then our binocular vision is impaired. If you have a misalignment you will not be able to see the image. If you have only one dominant eye than you will not be able to see the image.

Here is advice to see an image

"Hold the center of the printed image right up to your nose. It should be blurry. Focus as though you are looking through the image into the distance. Very slowly move the image away from your face until the two squares above the image turn into three squares. If you see four squares, move the image farther away from your face until you see three squares. If you see one or two squares, start over!

When you clearly see three squares, hold the page still, and the hidden image will magically appear. Once you perceive the hidden image and depth, you can look around the entire 3D image. The longer you look, the clearer the illusion becomes. The farther away you hold the page, the deeper it becomes."
