Optical illusions are visual experiences in which the brain misinterprets information sent from the eyes, resulting in a perception that differs from reality. The illusion we have today is a geometrical optical illusion, which is characterised by distortions of size, length, position, or curvature. In this case, the regular, repeating pattern of black and white lines can create a sense of movement or distortion, even though the image is static. These illusions can be challenging and daunting to figure out the hidden number.

Optical illusions, also known as visual illusions, are visual stimuli that are misinterpreted by the brain, leading to a perception different from reality. These illusions demonstrate how your eyes and brain work together to interpret visual information, often by relying on clues about depth, shading, lighting, and position. Visual illusions, dating back to ancient times, continue to be a subject of ongoing research. The study of visual illusions can be traced back to ancient Greece, where philosophers like Epicharmus, Protagoras, Plato, and Aristotle explored how our eyes and brain can misinterpret visual information.

The illusion today in the image, characterised by repeating diagonal lines, likely falls under the category of distorting or geometrical optical illusions. Johann Joseph Oppel is credited with being the first to systematically study and coin the term 'geometrical optical illusions. He published his findings in the mid-1800s. These involve distortions of size, length, position, or curvature. Such illusions highlight the brain's tendency to make unconscious inferences when processing visual information.
