Optical Illusions, Neurophysiology, Optometry, Cognition


Optical illusions are all around us in our daily lives. Their main method of action is to manipulate the brain into perceiving an image that differs from reality. Due to the illusion’s nature, it can activate certain pathways in the nervous system and allow us to perceive an image in a certain way. The visual and processing pathway of the human brain can be analyzed to illustrate the response when exposed to a physiological or cognitive illusion. This review summarizes our current understanding of visual sensing and its various responses to optical illusions, utilizing several well-known examples.
