The eyes shout what the lips fear to say,” said William Henry. This is for the eyes betray innermost emotions like fear, apprehension, joy or sorrow, without having to express it in words. Moreover being the language of the heart, they do not lie and hence play an important role during personal interviews and interpersonal relationship. Besides this eyes are the window through which we view the word around us. Other primary sense, like touch, taste- and smell, are directly or indirectly dependent on sight. This is for the eyes in association with the brain, decipher the colour thereby evaluating the temperature of an object, even before it is touched. Similarly, it evaluates edibles, based on their colour, shape and size, even before the taste buds come into play. Thus it augments the other senses, making life pleasant and enjoyable.
Besides enhancing the other senses, it enables us to enjoy the beauty of nature so abundantly available all around us. It does this by storing visual images of the object in the form of memory tags in the brain. This enables us to recognize objects and is therefore essential for learning, which makes us recognise and distinguish other creatures in the universe.
