The basis of optical illusions is visual deception. It isn’t your eyes playing a trick on you. Your eyes send signals to our brains through the retina, your brain then registers the information to create the image you are seeing. In the case of a visual illusion, the image the brain perceives differs from reality.

Treatment typically rests on the underlying etiology, so timely recognition and an understanding of causative mechanisms are crucial.

How common are hallucinations?

They’re not able to integrate that information and alternatively, it can sometimes strengthen the delusion,” Moe says.
