Below is a picture with a hidden 3D image.
Look at the two red marks above the picture. Diverge your eyes as though you are looking through the image into the distance. Diverge your focus into the distance until you see two squares above the image turn into three squares.
When you clearly see three squares, at that distance the hidden 3D image will magically appear. Once you perceive the hidden image and depth, you can look around the entire 3D image easily. The longer you look, the clearer the illusion becomes.
It will be easier to find out the 3D image if you print the magic eye picture (black and white will also work).
Inside the above Magic Eye picture you will find the following 3D image if you can successfully see the hidden three dimensional image.
If you still can not see the 3D picture please don't panic. It may take few more time to reveal. Please invest a little more time to find it out the magical 3D image.
It will be easier for you to find out the hidden image if you know actually how it works. To see a 3D magic eye picture your both eyes have to work. Here's a simple test. Hold a pencil directly in front of your eyes and look at it. You should see only one pencil. Then look beyond the pencil or through it at a distant object. The pencil should then appear to double. If you cover one eye, the pencil returns to single. If you can see this, you can try the magic eye.
