More from the MuseumTour expert:
An optical illusion is something we see when our eyes gather information and give it to our brain, which processes it in a way that doesn't match up with its actual physical measurements. Some optical illusions, such as afterimages, are thought to be caused by excessive stimulation to the eyes or the brain. Other optical illusions are cognitive - they happen when interacting and conflicting assumptions about the world lead to "unconscious interference".
