Our Sense of Sight

As I was told not to go into much scientific depth about our senses I will make it short. Basically our ability to see happens as light passes through our eye and is inverted through our lens. The light sensitive cells inside our eyes then picks up the image and transfers it to our brain via our optic nerve. It is then the job of the brain to interpret the data and make our image the "right way up". That said, it is reasonable to question how accurate the world around us is when the final image that we "see" is processed by our brain. Many people are also very

Visual illusions are caused by images that are sometimes misleading and deceptive causing our brains to cause illusions in what we see than what is actually there. Two examples I have chosen below include the Scintillating grid illusion in which the contrast of colours converge to cause the illusion of dots in the intersections.

The second illusion I have included an optical illusion whereby the two cirlces seem to be rotating when the viewers head is moving forwards and backwards while looking at the black dot.
