LASIK Facts

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

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 eye strain, 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.

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. 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.

ASTIGMATISM

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.

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.

Eye myopia, or near-sightedness, as it is popularly called, is one of the most common and annoying eye ailments.

The myopic eyeball is elongated by pressure of the two oblique muscles which bind the eyeball about the middle. The result is blurred, distorted vision when attempting to see a distant object. Myopia, in other words, involves a strain to see at the far point and it is our task to stretch the vision.

When the eyes are fitted with lenses, the light rays focus on the retina as in normal vision. On the contrary, the eyeball becomes more elongated as time goes on, and lenses must be made stronger and stronger to counteract the increasing myopia of the eye.

Myopia usually appears in school children between the ages of eight and fifteen. The reason appears to be that during puberty the child’s physical and nervous system is undergoing such drastic changes that the anxieties and fears often accompanying the confinement and competition of the school room create an entirely new series of strains.

These strains, in turn, are potent factors in the development of myopia and other visual defects. The result is that the child begins to strain to see, to develop a stooping posture as he crouches lower and lower over his book or walks with head down, trying to see the sidewalk. He develops headaches and nervous habits. Half-closing his eyes, he squints in an endeavor to clear his vision.

Little by little he begins to reveal the emotional characteristics of eye myopia. Automatically, they cut him off from many games and forms of exercise which the growing body needs. later, the patient’s eyes have lost much of their power of accommodation. The nerves and muscles of the eyes, depending on their glasses, have lost all flexibility of movement.

Actually, it impedes vision because the cramped neck muscles cut off the circulation of blood to the brain and the eyes.

Naturally, this creates a sensation of inadequacy.

Relaxation eye exercises for the eyes can also often help improve eye myopia.
