Transcript of Optical Illusions

MAIN IDEA

Light goes through the front part of the eye and reaches the

retina.

SUPPORTINGDETAIL

The retina has two kinds of cells - cones

and rods.

The brain interprets the image from the

retina.

MAIN IDEA

An optical illusion occurs when the

image as it is perceived by the brain is different

from reality.

SUPPORTINGDETAIL

Illusions are formed as a result of

mistaken judgment or erroneous vision.

MAIN IDEA

In short, the tiring of our eyes following

an excessive exposure to a certain

kind of visual can cause optical

illusions.

SUPPORTINGDETAIL

Staring at a certain color of a certain

amount of brightness tires our eyes, and as

a result, we may perceive things

differently.

MAIN IDEA

Some artists like to create optical

illusions in their paintings.

SUPPORTINGDETAIL

These include M.C. Escher, Piet

Mondrian, and Victor Vasarley.

They use color, shape, and curvature

to affect visual perception.
