Optical Illusion
An optical illusion is a visual phenomenon where what you perceive with your eyes doesn't exactly match the reality of the object or scene. It plays with the way our brain interprets light, color, and shapes, often leading us to see something different from what is actually there.
These illusions can trick the brain into seeing patterns, movements, or objects that aren't present or appear differently than they truly are. Optical illusions are often used in puzzles and tests to challenge your perception, requiring you to focus closely and think critically. They highlight the fascinating ways our brain processes and interprets visual information.
