A Guide to Understanding Common Eye Conditions

There are three different eye conditions from which a person may suffer, They are hypermetropia, presbyopia and astigmatism. These are explained below.

HYPERMETROPIA

Hypermetropia, commonly called far-sightedness, is the opposite from myopia. In this condition, rays of light are brought to a focus back of the retina. There are usually blurred vision, headache, and nervous fatigue in attendance upon this form of eyestrain, and always the difficulty in accommodating at the near point.

The so-called far-sighted eye is not, in actual fact, better able to see at a distance than the normal eye. It is simply unable to see the things that are close to it.

It is obvious that the person troubled with hypermetropia is unlikely to become the recluse "who always has his nose in a book." Reading over a period of time causes giddiness, clouding of the vision and often an inflammation of the eyelids. So this victim of eye-strain becomes the person of action.

PRESBYOPIA

The popular name for the eye condition presbyopia is middle-age sight and it is caused by flabby muscles which have lost their powers of accommodation. It has generally been supposed that presbyopia is one of the inescapable handicaps of increasing age and that nothing can be done about it.

Both presbyopia and hypermetropia have points of resemblance, the chief being that, in both cases, there is a strain to see at the near point. The person suffering from presbyopia can demonstrate for himself the effect of strain on his vision. If you find that you are suffering from discomfort after reading, try placing your palms over your eyes for a few moments, and you will discover when you start reading again, that you are able to read, with clearer vision. This improvement may be only of a few minutes' duration, but it will be evidence of the fact of strain.

Perhaps, from a personality standpoint, it might be said that no one gains so much by visual re-education as the victim of presbyopia. As this type of eyestrain ordinarily appears with middle age-though the list of exceptions is long, ranging from presbyopic eyes in the very young to normal vision at ninety-it is accompanied by the beginning of mental rigidity, of fixed habits of thinking and acting, of indications that a person has "become fixed in his groove."

ASTIGMATISM

In astigmatism, there is no exact focus because of an unequal pull of the muscles, which causes the eyeball and cornea to be unsymmetrical instead of a perfect sphere. Anyone can bring about a condition of temporary astigmatism voluntarily by staring so long and hard at an object that the sight becomes blurred and the image takes on strange shapes.

Psychologically, there is usually an emotional condition accompanying astigmatism that may lead to an impairment of the health or to nervous upsets. The person with the eye condition of astigmatism not only has difficulty in seeing distinctly but the object at which he is looking may take on strange shapes and forms. Of no case is it so true that "seeing is deceiving," for the astigmatic eye is the victim of odd illusions. He may see the object at which he is looking in multiple form; he may see one part of it and not the rest. It is small wonder, then, that he frequently tends to be a somewhat confused individual, as he is constantly registering distorted images upon his mind which struggles to identify and interpret these false pictures.

Sometimes these eye conditions can be helped with relaxation exercises.
