An optical illusion is a visual perception that differs from reality. It is a trick of the mind that occurs when the brain interprets information from the eyes differently than it actually is. Some common examples of optical illusions include the Müller-Lyer illusion, the Ponzo illusion, and the Zöllner illusion. These illusions can be caused by various factors such as the brain's interpretation of size, distance, and perspective.
