How to see a stereogram
A stereogram hides a 3D shape in a repeating pattern. You will not find it by looking harder. You find it by looking through the picture, as if it were a window and the shape were on the other side.
- Get comfortable. Sit about an arm’s length from the screen, or hold a print at reading distance. Make the picture as big as you can.
- Use the two dots. Each picture has two white dots in the dark strip at the bottom. Look at the space between them and let your eyes relax and drift apart, as if gazing at something far away. You will see the two dots double into four.
- Make three dots. Keep relaxing until the middle two dots slide together into one, so you see three dots in a row. Hold that.
- Slowly look up. Without changing your focus, move your gaze up into the pattern. After a few seconds the pattern seems to split into layers and the shape floats out.
- Explore. Once you have it, you can look around the picture and the shape stays. Blink or refocus and it goes away; relax again to bring it back.
Other ways in
- Nose to the screen: bring your face close so everything is blurry, then back away very slowly without trying to focus.
- Reflection trick: on a glossy screen or a framed print, focus on your own reflection, then let the pattern come into focus behind it.
- Give it time: most people need a few tries spread over a few minutes. Take breaks if your eyes feel tired.
Still nothing?
That is common. Every picture has a Reveal the hidden shape button so you can see the answer and try again knowing what to look for. Some people cannot see stereograms at all, often because one eye does most of the work. That is normal and nothing to worry about. If you wear reading glasses, try with and without them.
