Ever since we were children, we have marveled over the ability of optical illusions to trick us into believing something exists when we know for a fact that it doesn’t. Some of those optical illusions may be rather simple but others can be quite complex. In any case, it is an object that tricks the mind into believing that something is there because of the way that the eye perceives it.
Optical illusions have existed for thousands of years. The first recorded theory about those illusions is from almost 2500 years ago. At that time, they had no idea if an optical illusion occurred because it was the fault of the eyes or if it was an issue with the brain. Since that time, we have learned a lot about how optical illusions work and the research is ongoing down to this day. Even though that is the case, it is still something that amazes us whenever we see it.
An optical illusion occurs any time that the eyes are in conflict with the brain. Our brain expects to see something but the eyes may see something different. Regardless of why it happens, you are going to be amazed with the compilation of optical illusions that are shown in this video.
