Optical illusions are visual images that are created to trick our brain. They are also called visual illusions and are often used as simple intelligence tests; their popularity is reflected in their widespread use in pop culture.
There are three main types of optical illusions: literal, physiological and cognitive.
Literal illusions occur when our brain misinterprets the physical properties of an object.
Physiological illusions are caused by the way our eyes and brain process light and color.
Cognitive illusions occur when our brains make assumptions about what we see, even when the evidence contradicts those assumptions.
