Cause and treatment of refractive errors
Thousands of times it has been demonstrated that any abnormal work of the external muscles of the eyeball is accompanied by tension or stress, and to see that with the removal of muscle tension normal operation, and all errors of refraction disappear.The eye may be blind, he may suffer atrophy of the optic nerve, cataract or retinal disease, but as long as he does not try to see the external muscles are working normally and no error of refraction not.This fact gives us the means by which all of these conditions can be corrected, so long considered incurable.
can also be shown that every error of refraction corresponds to a kind of stress.The study of images reflected from various parts of the globe, proves that myopia (or hyperopia reduction) is always associated with the effort to see distant objects, while hyperopia (or reduction in myopia) is always associated with the effort to see objects in the near-point.This can make anyone who knows how to use the retinoscope, provided only that this tool not i
in the eye with the original normal vision strain to see near objects always leads to a temporary production hyperopia in one or all meridians.That is, the eye is either completely hyperopic or made some form of astigmatism, which is part of hyperopia.In hyperopia hyperopic eye is increased in one or all meridians.When myopic eyes strained to see any near object, myopia is reduced and may appear emmetropia (a condition of the eye, in which he focused for parallel rays, which corresponds to the norm for distance vision, but an anomaly of refraction when looking at near objects).Eye at the same time focus to the far point, despite the fact that he is still trying to see up close.In some cases it may occur even after the transition to emmetropia hyperopia in one or all meridians.All these states are accompanied by signs of increased stress and deterioration of vision, but oddly enough, pain and fatigue while usually reduced considerably.
On the other hand, if the eye with normal vision initially makes an effort to see distant objects, there is always a temporary myopia in one or all meridians.If the eye is already myopic, myopia increases.If hyperopic eyes straining to see a distant object, may appear or increase the pain and fatigue, but at the same time reduced hyperopia, and vision improves.This interesting result is the exact opposite of what we got when myopic straining to see in the near-point.Sometimes hyperopia completely disappears and there is emmetropia with complete removal of all signs of stress.This state can then go to the myopia with increasing voltage with increasing degrees of myopia.
In other words, the eye, which makes an effort to see the near-point, becomes flatter than it was before, in one or all meridians.If it has been extended from the start, he can move from this state through emmetropia, at which it is spherical in hyperopia, in which it is flattened.If these changes are made asymmetrically, the astigmatism will be in cooperation with other states.Conversely, the eye which strains to see distant objects, it becomes rounder than it was before, and can go from the flattened condition through emmetropia hyperopia in an elongated state of myopia.If such changes are made asymmetrical, again will appear astigmatism in cooperation with other states.
What can we say about the normal eyes, are equally applicable to the eyes, where the lens is removed.This operation usually leads to a condition of hyperopia.However, if the initial state of the eye has a high degree of myopia, removal of the lens may not be enough to correct it, and the eye may still be myopic.In the first case, the effort to see distant objects reduces the level of hyperopia, and strain to see at the near-point increases it.In the second case, the effort to see distant objects increases the degree of myopia, and strain to see at the near-point decreases it.Many eyes with removal of the lens (this state called aphakia eyes) for more or less long periods of time after removal of the lens tighten when near vision, creating a strong hyperopia, the patient can not read normal text.Accommodative ability seems completely lost.But later, when the patient becomes accustomed to this state, this voltage is often reduced, and the eye is able to focus accurately on close subjects.There have also been rare cases where without the aid of glasses to achieve good vision for distance, and for the near point.The eyeball with sufficiently lengthened to compensate to some extent the loss of the lens.
Similar phenomena associated with eye strain, have also been observed in animals.Many dogs I did myopic, causing them to strain to see a distant object.One very nervous dog with normal, as shown by the retinoscope, eye refraction gave a sniff of a piece of meat.She is very excited, alert, her eyebrows arched, and she wagged her tail.The meat is then pushed by the dog at twenty feet.The dog looked disappointed, but did not lose interest.At the moment when she looked at the meat, it was lowered into the box.The dog's eyes flashed excitement.She strained to see what happened to the meat.Retinoscope thus demonstrated that its vision was myopic.two active oblique muscle should be noted that such an experiment is possible only with animals having.Animals in which one of these muscles is absent or rudimentary, are not capable of extending the eyeball under any circumstances.
initially see the effort is a mental effort and mental stress in all cases accompanied by loss of mental control.Anatomically of effort to see distant objects may be the same as when viewing any near object without effort, but in one case the eye does what needs doing psyche, and in the other case it does not happen.These facts, I think, sufficiently explain why the vision deteriorates as the development of civilization.In conditions of civilized life the mentality of people is under constant stress.It appears greater than that of the uncivilized people, things that concern them.Modern people do not need to keep a cool head and be cured in order to see what is what determines their existence.If primitive man allowed himself to be nervous, it would quickly become extinct.Civilized same person survives and transmits its data psychic descendants.Animals react to the conditions of civilization as well as the people.I explored a lot of pets and animals in the zoo and in many cases found them myopic, although they are, of course, did not read, did not write, not sewn, and not typed.
Violation of the near-point, however, is just as characteristic of civilization, as well as violation of the distance.Myopic, although they see the near-point better than the distance, never see as well as people with normal vision.In hyperopia, which is more common than myopia, vision worse in the near-point than in the future.
Treatment is not how to avoid working near or distance vision, and getting rid of mental stress, which is the basis of imperfect operation of the eye at both distances.Thousands of times it has been proven that it can be done.
Fortunately, all the people if you want to relax, under certain conditions.When all errors of refraction uncomplicated effort to see may be temporarily reduced if the patient will have some time to look at clean the wall without trying to see.To achieve continuous relaxation sometimes requires a lot of time and ingenuity.The same method is not suitable for everyone.The ways in which people strain to see are infinite.Almost equally diverse methods must be used to reduce the voltage.However, in practice always technique that brings the most success in the end turns out to be the same, namely, the relaxation.Constant repetition and multiple display all possible means should emphasize that perfect vision can only be purchased relaxation.
Most people, when they were told that the rest or relaxation eliminate the disadvantages of them wondered why this does not sleep.The eyes are rarely, if ever, fully relax during sleep.If they were alive, when a person was awake, this stress will definitely be a greater or lesser extent, continued during sleep, in the same way as the continuing stress of other parts of the body.
idea that relaxation gives rest to the eyes in order to subsequently be able to use them as erroneous.The eyes are designed to see if and when they are open, they do not see it because they are under such stress and have such a large error of refraction that can not see.Near vision, although it is carried out with the help of muscles, it is no more eye strain than distance vision, performed without their intervention.Using the muscle does not necessarily lead to fatigue.Some people can run for hours without getting tired.Many birds sleep standing on one leg.Fingers of feet impact the swinging branch, but the muscles in this case remain unspent obvious tension.
fact remains that when the mind is at rest, nothing can tire the eyes.When the mind is under stress, nothing can give your eyes a rest.All that gives the mind rest, good for eyes.Probably each of us notice that tired eyes slowly when you read some interesting book, as opposed to reading a book boring or difficult to understand.A schoolboy can sit all night, reveling in romance and never remembering at the same time of their eyes.But if he will try to sit up all night with their lessons, he quickly discovers that his eyes were very tired.One girl, who had such a strong vision is normal that the naked eye could see the moons of Jupiter, he became myopic when she was asked to decide in your mind any math task, the subject is too unpleasant for her.
Sometimes the conditions that lead to mental relaxation, look very strange.For example, a woman could correct their error of refraction, when looking at the test, bent forward at an angle of about 45 degrees.This relaxation was maintained and after she took a vertical position.Although it was inconvenient position, is somehow sought thought that it improves vision, and it is thus did give such an effect.
time required to achieve the continuous improvement of vision varies within a wide range of different people.In some cases it is sufficient for 5-15 minutes, and I think the time will come when it will be possible to quickly help anyone.This question
only accumulate a larger number of such facts and presenting them, which allows you to quickly understand and internalize them.Today, however, often have to stretch treatment for weeks and months, although refraction may not be greater in magnitude and duration than in those cases, which quickly cured.
In most cases, to avoid relapse, treatment should continue as a few minutes per day.As anyone familiar object able to take the effort to see the daily reading of the Snellen test is usually sufficient for this purpose.It is also useful (especially when imperfect near vision) to read the fine print every day, holding it so close to the eyes, as it only can be done.When there is improved vision, it always goes on continuously.However, to achieve a level of higher than normal-telescopic or microscopic - is very rare.But even in such cases, the treatment can also be successfully continue - determine the limits of human visual power is not possible.Regardless of how well the eye, it is always possible to improve it.
Daily training in the art of the need to prevent such deviations in vision, which is subject to almost any eye, no matter how good his eyesight.Of course, no training system does not give an absolute guarantee against such deviations under all possible circumstances, but the daily reading of small remote familiar letters did much to reduce the tendency to stress that such negative circumstances appear.All people, from which depends the safety of others, to do such training.
Usually people who have never worn glasses, more easily cured than those who wear them.Therefore, glasses should be rejected at the outset of treatment.When this can not be done without major inconvenience or when a person is forced in the course of treatment to continue their work and can not do it without the glasses, their use can be resolved for a while, but it always keeps improving.People of all ages have achieved success in the treatment of refractive anomalies relaxation, but children usually (though not always) have reacted much faster than adults.If they still do not have 12 or even 16 years and they have never worn glasses, they are usually cured in a few days, weeks or months, and always within the year by reading the daily checklist.
