Need to consider how there is tension and muscle contraction, and then become clear the root cause of visual impairment.
Dr. Bates is quite clearly states that he believes the cause of mental impairment, mental stress, which, respectively, gives rise to physical strain on the eyes and eye muscles and nerves, leading thus to a visual impairment.
He believes that a nervous temperament, has a tendency to psychological and mental stress is the cause of most serious shortcomings of view. He considers less serious defects as a result, mainly mental stress (and hence the voltage on the brain and nervous system) generated by overwork, anxiety, fear, etc. The degree of impairment varies in all cases, depending on the temperament and condition of the nervous system of the individual. As proof of his theory of Bates has concentrated its efforts on therapies that address the mental state of stress. Thus, a key provision of the Bates method is relaxation (relaxation).
If a man is able to remove the mental stress, then your eyes (along with their associated muscles and nerves) will not be in a state of stress. Conversely, if we can reach a relaxed state of the eye and the eye muscles and nerves, then the brain (and hence the mind) will be in the unstressed state. Thus, it is clear that the method of Bates aims to achieve the ability to remove the state of tension as the mental and physical. Only under these conditions it is possible to achieve good outcomes. Some cases of failure it is possible to explain the patient's inability to remove the tension adequately or neglect of physical relaxation.
Any factor, not only mental but also physical, and able to cause muscle strain your eyes, is a potential cause of visual impairment.
The more causes of visual impairment can be identified, the more confidence that the treatment can be successful. Therefore, in this book so much attention is paid to a variety of factors that must be taken into account, relying on the success of treatment.
In search of the possible causes of the stress state of the eye muscles must be borne in mind that the eye is part of the body and as such is exposed to conditions affecting the body as a whole. Treat the eye as something separate, which can operate completely independently, it would be a mistake.
Therefore, you should focus on factors that have an impact on the body as a whole.
It is known that diseases such as diabetes and nephritis, have an effect on the eyes, and among physicians recognized that in some cases based on cataracts is diabetes. Most non-specialists know that the spots appeared before my eyes, and "float" in the liver and digestive problems.
But the close connection between the eyes and other parts of the body is fully supported by those engaged in iridology. Pioneers iridodiagnostics did a great job to show that any change, functional or organic, in any body part or organ is reflected in his eyes, changing the color of the iris, which is directly connected with this part of the body or authority. This is a wonderful demonstration of the result of the relationship between the nerves of the eyes and central nervous system. If the eye is influenced by changes in individual organs, how much this effect increases when the whole body is involved?
Many doctors who practice natural therapies, found that the inflammatory state of the eye such as conjunctivitis, iritis, etc., should not be regarded as a disease affecting only the eyes and nothing more, but as a symptom of overall imbalance in the body due to excessive consumption of sugar, protein, etc.
At the same time, they came to the conclusion that the cataract is only a symptom of a deeper (and hence chronic) manifestations of the same state.
Experience has shown that malnutrition not only affects the eyes themselves, but also on the processes by which the vision, because the muscles and blood vessels surrounding the eyes, make a "share" in the process of delay in the body of harmful substances due to metabolic disturbances, which in turn, stem from malnutrition.
As soon as the muscles and blood vessels "clog" the proper conclusion of hazardous substances is not possible and muscle instead of being soft and flexible, becoming rigid and strapped. All of this ultimately prevents the normal accommodation, and then, as a direct consequence, influences the shape of the eye. The end result is blurred vision.
The cause of many cases of nearsightedness, farsightedness and astigmatism is nothing like all of the above, and presbyopia occurs almost entirely because of this.
Until recently it was believed that when a person reaches middle age, the eyes naturally change shape, thus making it difficult for normal vision of close objects and causing presbyopia. This is seen as an inconvenient but necessary price we must pay for such a long stay in this world. And this difficulty is avoided by wearing convex glasses.
Only a few of the millions of people suffering from presbyopia, are aware that poor diet for 45 or 50 years may be the cause of these changes in their visual abilities. But no doubt about the fact that many people suffering from presbyopia, can restore normal vision, simply adhering to a sensible diet and doing some simple exercises for the eyes.
To emphasize the vital connection between nutrition and vision, it should be noted that there are many documented cases of significant impairment of healing through a simple post, which contributes to the conclusion of harmful substances from the muscles and blood vessels in the eye, causing the muscles relax and vision improves our Duke peterson vision without glasses here.
Blood and nerves.
If the delivery of blood and nervous energy to the eye is impaired, normal vision impossible and, therefore, any factor that could affect the condition of the blood vessels or nerves of the eye, may be a possible cause of visual impairment.
Of course, it is clear that mental stress and poor diet cause disruption to normal delivery of blood and nervous energy to the eyes, but there are some purely mechanical means such violation. The main reason for the mechanical disruption of the normal blood supply and nerve impulses in the muscles of the neck is covered.
If these muscles are shortened, stress state, they act on the cervical vertebrae, making it difficult for the normal action of the nerves, "serving" the eye. In addition, affected vasomotor nerves that control the size of small arteries as a result of restricted blood flow to the head.Therefore, in all cases of visual impairment need to make sure that the back of the neck muscles are completely relaxed, that there are no irregularities in the vertebral system.
I should add that massage and other back and neck exercises are very useful in many cases, cure was achieved was with their help. In addition, you should understand that in most cases of visual impairment stress on the eyes and eye muscles, blood vessels and nerves (mainly due to the constant wearing of glasses) is transmitted to the muscles of the back of the neck and they, in turn, become strained.
It is obvious that the complete restoration of normal vision is impossible without relaxation of these muscles and, therefore, it is clear what significance to the overall course of treatment are exercises for the neck.
