Optical Illusions

Give Your Brain a Boost with Optical Illusions!

See is believing, right? Well, in the case of optical illusions, you may find it hard to believe what your eyes are telling you. Objects that seem to be different sizes are really identical; pictures move on the page; images that appear one way become something else altogether. Don't run off to the optometrist---this is all part of the experience, and the fun!
