Stereograms-To increase your concentration

1. The main trick to seeing stereograms is learning to de-couple your focus and eye positioning. You will need to position your eyes as though you were looking at an object about twice as far away, while focusing on the image. Instinctively you focus on the object you are looking at...
2. As we said above, you'll need to LOOK at something about twice the distance of the image. It turns out we have something that is almost always available that is the exact distance...
3. your reflection. By looking at your reflection on your computer monitor.Get very close to the stereogram, and very, very slowly pull it away (or move away from it). At first you won't even be able to focus on the image... However, keep moving the image in and out, relaxing, and it will appear.
4. If possible, copy some of the simple SIRDS images onto a transparency. Next, hold it out in front of you halfway between your eyes and a wall. Now change your focus from the image to the wall and back again repeatedly. If you do not see the effect immediately, you can move the image in and out while continuing to change your focus back and forth.
