How the Eye Works

They eye is a fascinating part of the human body.  It allows living creatures to view and interpret other organisms, places, and objects.  The eye is made up of multiple parts including lens, pupil, cornea, optic nerve, and retina. the pupil controls the amount of light that passes through the eye.  The iris in the pupil opens and closes adjusting to the light being emitted from multiple sources.  The lens in an eye is needed in order to focus the light being received.  It focuses the light delicately onto the retina.  The retina is in the back of your eye and is filled with photoreceptor nerve cells.  These cells form impulses after being exposed to the light, which are then sent to the brain through the optic nerve.  The optic nerve serves as a highway for impulses to be sent to the brain, resulting in the formation of visual images.  All of this happens within in an instant. 

Blind Spots

The picture to the left shows why people have a blind spots.  The arrow in the picture represents the location of the optic nerve, which connects the eye to the brain.  When your eye looks at the diagram on the top of the page, the dot is projected onto the part of the eye where the optic nerve is located.  There are no receptors at this location.  Due to the absence of receptors, there is no way for the light to be sent through the optic nerve to the brain.  Without ever reaching the brain these lights will never be interpreted to form visual images, thus resulting in the blind spot. 

Perspective and Your Eyesight

The eye in a human body provides visual perspective, which is the most popular.  Visual perspective is the easiest to understand and notice.  People are able to view or notice visual perspective without trying to find a deeper meaning within what they are seeing.  For the most part, in art, when perspective is mentioned it is often associated with words like linear perspective and multiple perspectives. Linear perspective and multiple perspectives are things that you can immediately pick up as you view a painting or drawing.  The light emitted from the painting is immediately focused by your lens and interpreted by your brain to reveal an image that shows a three dimensional effect.  Although every person has their own interpretation on a certain object or moment in time that they experienced.  The roshomon effect reveals that each person will perceive a certain situation in their own way.  Every take on the event will usually be similar, with some exceptions.  These exceptions are the tiny things that each person has viewed differently.  For example, in some sports there are multiple referees. Those sports containing more than one referee have some controversial moments.  There are times in a game where the referees will come together to discuss a ruling on the field.  In baseball the perspective of the umpire, behind home base, is very important when it comes to calling a strike on a pitch but when the batter checks his swing the first and third base umpires' perspectives are even more important. Referees have come together in order to discuss whether or not a player checked his swing.  The common scenario seen in baseball is the umpire behind home base will call a check swing a strike, while the other two will see it as a ball.  It all comes down to how you interpret the actions taken by the player in the moment.  This not only deals with the eye, but your mental state as well which may be influenced by previous experiences.
