The human being has five senses, but when most people are asked what sense they would like to lose the least, it takes little thought for them to come to the conclusion that their greatest gift is their sight. The eye, controlled by the brain, is one of the most interesting organs in the body and it is the sense that brings us closest to our world. This paper will examine the physical workings of the eye and its operation in relationship to the brain. This paper will be composed of a review of texts on the operations of the eye. All of the research will be secondary in nature and this paper should be viewed as a report of existing material with no effort to develop any creative hypothesis on the operation of the eye.
