An illusion is an image or representation believed to be real in our mind’s eye, but that is not actually real. In other words, because of the way our eyes and brain work, our eyes are tricked into seeing something that is not really there or into seeing something happen that did not really happen. Illusions can be very deceiving, and magicians use illusions to their advantage to make the audience believe that something happened by magic. Optical illusions tell a story about how our eyes and brain work together to allow us to see.
