Stereograms are 3D images hidden within another picture. It looks like miracle!HOW TO VIEW STEREOGRAMS:1. Pick a spot on the picture (the middle seems to work best) and just stare at it.2. Allow your eyes to relax, don't just stare AT the image, try to stare THROUGH it. You'll notice your eyes will go slightly out of focus. This is normal.3. Keep staring, don't give up, once you begin to see the first image, it gets much easier.4. Reasons why you can having trouble viewing the stereograms:*** The basic principle behind a stereogram depends on the ability for a person to merge multiple objects into one. There are many factors that could inhibit a person's ability to see the object hidden beneath the initial surface. As an example....place your thumbs and index fingers together in the shape of a triangle, and find an object in the distance to look at through the triangle. It must be a distant object! Independently close one eye, then the other....you will notice that you were only able to see the complete object through one eye without moving the triangle. This concept is called eye dominance. Sometimes the brain will shut off one eye, and rely on the dominant eye, if the object to be viewed doesn't come in focus. There are many people who need corrected vision that don't realize it because of the human ability to adapt.*** Another possible cause is convergence. At close range 12-18 inches (or 30-40 cm), your eyes converge an average of 3mm...but this is not so for everyone. Just as you have a dominant eye for distance, you will also have a dominant eye for near.GENERAL HINT:The most sure fire method is to bring the image as close to your face (or bring your face as close to the image), until your nose is almost touching the image and everything is blurry. Then very, very slowly, move the image back, or move back from the image. Don't try to focus on the image itself because if you do this you'll never see it. Relax your eyes and don't try to focus on anything. When you do this, and it may take several tries, you should start to get the feeling that you are seeing depth.If this happens, resist the temptation to focus on the image or you'll lose it and have to start all over again. Just go with it and let your brain pop the hidden image.Nothing is more exciting than seeing your first hidden image Stereograms 3D. And once you have seen one stereogram, the next, and the next, and the next one will get easier. We promise!
