An optical illusion is a perplexing representation of a thing, a drawing, or a photograph that appears differently depending on the angle from which it is seen.
There are many different kinds of optical illusions, including cognitive, physiological, and physical ones.
Due to their ability to shed insight on perception, these optical illusions fall under the purview of psychoanalysis.

By adopting a "colour assimilation grid illusion," this black-and-white graphic deceives our minds into believing it is a coloured image.
This effect was created by overlaying the original black-and-white image with a grid of coloured lines.
Bart Anderson, an optical scientist, told Science Alert "Due to the fact that many of the receptive fields that code colour are relatively big, the colour system is what vision scientists refer to as "low pass." The achromatic backdrop is "averaged" with the grids and applied to that area of the image."
The way our brains function is always fascinatingly revealed by optical illusions.
Certain arrangements of colour, light, and patterns can deceive our minds into seeing something that isn't actually there.
