Optical Illusion
An optical illusion is a visual phenomenon in which the perception of an image differs from objective reality. These illusions trick the brain into seeing something that isn't actually present or misinterpreting what is seen.
This happens because the brain processes visual information based on past experiences, expectations, and context.
Optical illusions can occur in many forms, such as shapes appearing distorted, colors seeming to shift, or objects seeming to move when they are actually still.
There are three main types: literal illusions, physiological illusions, and cognitive illusions .
These illusions are not just entertaining; they also provide valuable insight into how our visual system and brain work together to interpret the world.
