What does optical illusions mean?

An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality.

What part of the brain do optical illusions affect?

Optical illusions provide fertile ground for such study, because they involve ambiguous images that force the brain to make decisions that tell us about how we perceive things. Most optical illusions result from processes in the cortex, but some do originate in the retina.

Is optical illusions bad for your eyes?

If you have wondered whether optical illusions are harmful to your eyes, there is no need to worry. According to the Mayo Clinic, viewing optical illusions will not hurt your vision, unless you spend considerable time staring at an image on the computer screen and develop eye strain.

The brain is set up to receive and interpret messages from the eye. Optics, a branch of physics, studies the interaction of the light and the eye and this interaction plays an important role in optical illusions. Optical illusions use light, colors and other features to trick the mind.
