Information about optical illusions and optical perception ( How vision works ) :

An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality.

Visual perception is the ability to interpret the surrounding environment by processing information that is contained in visible light. The resulting perception is also known as eyesight, sight, or vision.

The human visual system analyzes the interactions between visible electromagnetic waves and the objects in our environment, extracts information about the world from them, and makes visual perception possible.

Visual perception is considered a dynamic process that goes far beyond simply replicating the visual information provided by the retina.

To perceive is to create a figure or shape that does not necessarily appear as such in the real world but that we can represent mentally so that we can recognize it under various conditions. Hence, by studying the way that the brain fills in missing or ambiguous visual information, we can learn a lot about the way that we perceive the world.
