Right Eye  <-   Cross-eye Method   ->  Left Eye


With the cross-eye method, your right and left eyes will see the images on the left and right side, respectively.

  1. Maximize this window.
  2. Sit directly in front of the monitor (normal distance) and straighten your head! (important)
  3. Put out your finger about 10 inches away from your eyes in front of the two images.
  4. Stare at your fingertip for a while.
  5. While still focusing on your finger, move your attention to the monitor. You will notice you see 3 or 4 blurred images behind your finger.
  6. Move your finger closer to or away from your eyes slowly until you see 3 images. (Two of the four images overlap.)
  7. Now, without moving your eyes or finger, try to focus on the overlapped image in the center very, very slowly. If the overlapped image starts to move apart, focus again on the finger and start over.
  8. Put down your finger and say "Wow!"

Left Eye  <-   Parallel Method   ->  Right Eye

With the paralle method, your left and right eyes will see the images on the left and right side, respectively. (Each image cannot be bigger than just a few inches on the screen. The cross-eye method is better for seeing bigger images.)

  1. Resize this window until the width of the window is 5 inches or so on the screen. (The width of each image should be the same as the distance between your eyes.)
  2. Move your head very close to the monitor (your nose should almost touch the screen) so that your eyes will be right in front of each image.
  3. Don't try to focus on the image yet. Relax your eyes as if you are looking at something in the distance.
  4. After a while, you start to see two blurred image overlapping with each other. Then start moving your head away from the monitor very, very slowly. Keep your head directly in front of the monitor.
  5. When your eyes are at a normal distance from the monitor, try to focus on the image very slowly.
