Dec 6, 2023 · Illusions work because the part of the brain that controls vision misinterprets signals the eyes send. When you look at an optical illusion, the light waves reflect off the picture and travel to the back of each eye to the retina, the tissue that perceives light and converts it into signals for the brain. Your brain uses signals from the retina ...

Oct 4, 2023 · Cognitive Load. Cognitive load refers to the amount of mental effort required to process information. When we look at an optical illusion, our brain is forced to work harder to interpret the image, which can lead to cognitive overload. This can cause us to make perception errors or miss important details.
These are optical illusions – pictures that play tricks on your eyes and confuse your brain. Besides being fun, optical illusions help us to better understand vision and demonstrate how closely our eyes and brain work together. Scientists have studied optical illusions and they still don’t completely understand or agree about how they work.

The reason why we do not experience incomplete images of objects is that the two eyes fill in for each other’s blind spots (Albert and Gamm, 2019).
