An optical illusion is a visual phenomenon where the brain perceives something differently from reality. These illusions occur due to how our brain processes visual information.
Types of Optical Illusions
- Literal Illusions: When the brain perceives an image that is different from the physical reality.
- Physiological Illusions: Created by overstimulation of the brain with patterns, colors, or brightness.
- Cognitive Illusions: When our perception is influenced by expectations and prior knowledge.
