I believe we have optical illusions to make our eyes and brains think in different ways then they normally think! Without optical illusions, we wouldn't look at things the way we look at them... i guess(?).
An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed by the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types of illusion - literal optical illusions that create images that are different from the objects that make them, physiological illusions that are the effects on the eyes and brain of excessive stimulation of a specific type - brightness, tilt, color, movement, and cognitive illusions where the eye and brain make unconscious inferences. for mine
to make a optical illusion you need a chair or something else you can sit on , then put your chair dia ganale and then further in the background pretend you are sitting down.
because its the clash of colours that basically make the illusion?
