What is a cognitive visual illusion?
A cognitive illusion is usually a picture that is meant to show an ambiguous image or images.

What are visual illusions caused from?
Visual illusions can be the result of a stroke in the occipital lobe , which is located at the back of the cerebral cortex and is the main center for visual processing. Stroke can be caused either by a clot obstructing the flow of blood to the brain (called an ischemic stroke) or by a blood vessel rupturing and preventing blood flow to the brain (called a hemorrhagic stroke).
How do visual illusions occur?
Visual illusions occur due to properties of the visual areas of the brain as they receive and process information. In other words, your perception of an illusion has more to do with how your brain works — and less to do with the optics of your eye.
What is literal optical illusions?
Literal Optical Illusions. These illusions are created when our eyes perceive an image and our mind fills in gaps that don’t actually exist creating an image that’s different from the object that makes them, or focuses on specific areas of the image resulting in us “seeing” something that isn’t actually there.
