An optical illusion is a phenomenon that tricks our brain to believe in something that's either wrong, or not there in the first place. Our eyes and brain work together to help us see the things around us. There are two types of optical illusions. Our eyes cause the first type of illusion, Eyes see something wrong and send false visual signals to the brain. The second type of illusion is caused by the brain, where it automatically makes a false assumption based on the information sent by eyes. Optical illusions are fun!

15.Albert Einstein or Marilyn Monroe??
This fantastic image looks like physicist Albert Einstein. However, move a few feet away from the screen and suddenly it'll transform into Marilyn Monroe. The work of Aude Oliva and her colleagues at the Massachusetts Institute of Technology, the illusion was created in three steps. First, the researchers obtained a photograph of Marilyn Monroe and removed the fine-grained facial features, such as any wrinkles or other blemishes. Second, they obtained a photo of Albert Einstein and removed the more coarse features, such as the shape of the mouth or nose. Finally, the two images were superimposed on top of one another. Because the fine-grained features are visible during close-up, the image looks like Albert Einstein when you're just a few inches away from the page. However, move a few feet away and suddenly only the coarse features are visible, magically transforming the image into Marilyn Monroe.
