The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.

The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye.

Lachrymal glands or tear glands are situated

Implanting standards, right values, the science of good and evil are an essential part of education. Many forces thwart this to work, but two of the most serious hindrances to it are examinations and specialization. The examination system is both an opiate and a poison. It is an opiate because it lulls Man into believing that all is well when most is ill. It is a poison because it paralyses or at least slows down the natural activities of the healthy mind. Man finds himself a creature of unknown capacities in an unknown world, wants to learn what the world is like, what he should be and do in it. To help him in answering these questions is the one and only purpose of education. However, tests of progress are useful and necessary. Examinations are harmless when the examinee is indifferent to their result, but as soon as they matter, they begin to distort his attitude to education and to conceal its purpose. For disinterestedness is the essence of all good education and liberal education is impossible without it.
