THE EYE. The normal sighted human eye perceives an object which is ‘described’ by light rays and how they are bent by it . Usually‚ the image of the object is picked up on the retina‚ on the area of the Central Forea as an upside down picture which is then ‘righted’ by the brain in order that the object may be seen. Different distanced objects are perceived by the eye and the lens is the part that makes this possible. Objects which are close to the eye are seen by the eyes’s lens becoming thicker

The eye is a rather small part of the body that makes up seventy percent of the humans total sensory ability. That is why we chose to describe the eye. Each part of the eye works together as a whole.
