Perception of Illusion

We live our lives through filtering; we are unable to process everything around us, so we naturally ignore somethings. We are consumers of everything around us however most of this happens subconsciously so as a designer you must design so the consumer is consciously aware of it and doesn’t naturally filter it out.

The way we process images is the light is diffracted through the lens in our eye and hits the retina at the back. When it hits the retina, the image is inverted, messages are then sent to the brain via the optical nerve where the brain then decodes and flips the image. Our vision does have blind spots to it; this is when the diffracted light hits an optical nerve rather than the retina. Colour blindness is most commonly with the colours red and green but can also be for the colours yellow and blue.

There is a nature vs nurture question about our depth perception, is it something we are born with or something we learn in our earlier years? A test was done with young infants to see what they could find. A child was placed onto a checker floor with their mother stood on one side calling the child, the child would then proceed to crawl to the mother. The mother then stood on the other side, where the infant would have to crawl over a glass floor to reach her, it was perfectly safe, however the majority of the infants hesitated to crawl across the glass flooring.
