Preface


EYE TRICKED YOU!

Most of us don't think too much about our amazing sense of sight. It seems to work automatically, but it doesn't. How do we sort out what we see? Most of that job is done by our brain and not our eyes!

When you see something, light enters your eyes. The light is focused on sensitive "screens" at the back of each eyeball. The information focused there is sent to your brain. Then it's your brain's job to make sense out of the information it gets.

This is where optical illusions come in. "Optical" has to do with your sight. An "illusion" is a kind of trick. When you look at an optical illusion, some part of the process just doesn't match up. This may happen because of how the eye works. It may also happen because of how the brain works. So you may see things that really aren't there or that just don't make sense!

Much of the fun of this book involves "playing" with your sense of sight so you are fooled. It has nothing to do with how smart you are or how old you are.You will be tricked.

To get the most out of this book, read the question at the top of the page. Then look at the picture. Do your best to "figure it out" before looking at the descriptions at the bottom of the page.

Now go have some fun!
