An optical illusion (also known as a visual illusion) can be described as “visually perceived images that differ from objective reality”. Basically, the information that’s gathered by the eye is processed in the brain to yield an observation that does not match with a physical measurement of the originating source.

Here are 5 optical illusions that may melt your brain (“may” because not all people experience the same perception).  Click the images to see them in a larger format.

Do you see the square in the middle moving?

Are the circles below spinning?

    Those optical illusion posters that were popular a few years ago were a puzzle to me. Try as I would I could not make the 3-D picture embedded in them appear. In addition I will sometimes walk in to a room where the TV is on and when I look at the screen I can’t make sense of the picture for a few seconds. It’s like looking at a mixed up jigsaw puzzle. I think partly I have a depth perception problem. Interesting though.
