Design Case

God created mankind with the five basic features for survival, the five human senses. Prehistorically, Aristotle is ascribed with the conventional classification of the five sense organs: sight, smell, taste, touch, and hearing. Without these senses, we are not able to survive. Simply to say, sight, hearing, touch, smell, and taste are our life sustenance.

It is with these senses we are able to utilize the given privilege to experience the blue of a cold winter sky, the sweetness of a peach, the beat of our favourite tunes, the yielding, warm feel of a baby's skin and the fresh smell of morning dews. Very often, humans tend to take our senses for granted, but can one imagine what life would be like without them.

Each of the 5 senses consists of organs with specific cellular formations that have receptors for individual stimuli. These cells are connected to the brain via nervous system. Sight is presumably the most developed sense among the five, followed intimately by hearing.

Eyes are very essential to the human body. It helps the human body to perform tasks with dexterity. With no vision, we would not be able to see the splendour of this wonderful world.

With vision, we can make a distinction between distant objects from close ones and ascertain colours and shapes.

Other than the biological structures and general functions of the eyes, there are other some amazing facts related to the eyes. An often heard of old expression quotes that "The eyes are the window to the soul." While that may not be factually correct, they do divulge very much of our thoughts and emotions from time to time. Whenever we see someone or something we fancy, our pupils dilate and grow larger. This is an instinctive and irrepressible physiological reaction. Fictional or real life love stories very often commence at the moment two pairs of eyes meet. When a person lies or feels guilty about something, he or she tends to look away or avoid eye contact. This is also an involuntarily reaction which our eyes betray our thoughts. We are seduced by "bedroom eyes," cautious of "shifty eyes," and terrified of looking at the "evil eye." Those with "kind eyes" and eyes that "sparkle" or "twinkle," are the pull factor while those "dead behind the eyes" normally give the repelling push. Other than these figure of speech or the stunting effects of eye contact as social skill, the eyes also possess some mythical beliefs. Primeval societies believed the eyes were magical organs, being so eyes were sculpted into
