An optical illusion is a fascinating visual phenomenon in which the brain sees something that isn’t there—or perceives it differently than reality. These illusions use shapes, patterns, colors, and spatial relationships to confuse or mislead our visual perceptions.
In most cases, what the eyes see does not match what the brain interprets, resulting in unexpected and often enjoyable outcomes. Optical illusions are not only entertaining, but they also provide an excellent opportunity to put cognitive skills such as attention to detail, concentration, and pattern recognition to the test.
They test how we process visual information and show how quickly (or slowly) our brains detect anomalies.
