|  | | | Magic Eye - Stereo Viewing
 | | Students rest their chin on the chin rest and slowly slide the Magic Eye image away. |
There is a reason why we can see in 3 dimensions. It is because we have two eyes. Each eye captures its own view and the two separate images are sent on to the brain for processing. When the two images arrive at the same time in the back of the brain, they are brought together into one picture. The mind combines the two images by matching up the similarities and adding in the small differences. The small differences between the two images add up to a big difference in the final picture! The combined image is more than the sum of its parts. It is a three-dimensional stereo picture.
