Optical illusion: how many faces can you find in this image? What is behind the phenomenon of optical illusion? Even when we think our eyes are focusing on a certain point, they move quickly and imperceptibly from one side to the other. They “capture” separate elements, which the brain then interprets as an image that makes some sense to us.
At the same time, our brains can also make mistakes and be fooled by familiar patterns and experience. Many of us perceive a cloud floating above our heads as resembling, say, an animal silhouette or a human face. Another person might see something else. Set the timer for 20 seconds and let’s go! This is no ordinary picture of trees. The branches are intertwined in a strange way and hide several human faces. Can you find them all?
