Illusion is derived from the word illudere, which means to mock or trick. So, the primary idea of an optical illusion is to deceive the human brain by tricking it.
There are three types of optical illusions- literal, physiological, and cognitive.
The beauty of optical illusions is that they engage the user's attention for a brief time, which helps sharpen the brain.
So if you are an optical illusion enthusiast, here's one that might intrigue you. It challenges you to spot 3 socks among a heap of sweaters within 10 seconds.
