Optical Illusion 

An optical illusion is a visual phenomenon where the perception of an image differs from the reality of its physical properties.

This occurs because the brain interprets visual information in a way that may be influenced by various factors, such as light, color, contrast, or context.

The brain relies on previous experiences and expectations to make sense of what it sees, sometimes leading to misinterpretations.

Optical illusions can involve distortions in size, shape, color, or movement, and they often demonstrate the complexities of how the human visual system processes information.

Some illusions are simple, like the classic "two identical objects that appear different," while others, like those involving motion or three-dimensional depth, can be more intricate.

Essentially, optical illusions highlight the gap between how we think we see the world and how we actually perceive it.
