Detailed 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.

Optical illusions provide fertile ground for such study, because they involve ambiguous images that force the brain to make decisions that tell us about how we perceive things.

So, What visual perception tells us about mind and brain ?

Recent studies of visual perception have begun to reveal the connection between neuronal activity in the brain and conscious visual experience.

Conscious visual experience is thought to be based on activity in visual areas of cerebral cortex, which receive input from the retina. Early cortical structures are organized topographically with regard to the visual world. This topography can be exploited to investigate the role of different visual areas in perception.
