The term " Computer Syndrome "Today to denote a special condition, which can not be called a disease in the usual sense of the concept. The official list of diseases of the disease does not exist. However, modern human life is directly linked to long stay at the computer, so that the experts-ophthalmologists are increasingly hear complaints from people on some unpleasant phenomena that occur as a result of an extended stay for a computer monitor. Because of such features emerged a direct prerequisite for the formation of a new concept among the list of eye diseases that doctors refer to as the computer eye syndrome .

What is a computer syndrome?

Computer eye syndrome - A condition in which a person complains of a constant eye strain, headaches, loss of visual acuity. Sometimes the eyes turn red, and there is a constant feeling of a foreign body in the eyes. The symptoms occur in someone who has worked continuously for a long time at the computer. At the same time there is exactly the stipulated time, after which the patient begins to celebrate the presence of the described symptoms. In each case it individually. Very often the amount of time before these manifestations caused by the presence of other eye diseases, such as myopia . Also, these symptoms will occur in people suffering from vegetative-vascular dystonia .

With the development of computer syndrome, most people are very long period of suffering from the symptoms and do not seek medical help. Because of this situation can be much worse. Often in advanced computer syndrome in humans is a constant redness of the eye, significantly deteriorating eyesight, have problems reading. Only then begins to analyze what causes this condition provoked.

Causes of computer syndrome

Formation of a man going on a gradual, evolutionary way. And to work with the image on the computer monitor is turned completely unprepared. The main reason for the development of a human computer vision syndrome - is a permanent fixation of view on a computer monitor, thereby greatly reducing the frequency of blinking. In view of this happening drying tear film   on the cornea of ​​the eye Which in turn provokes redness and other unpleasant symptoms. It is believed that in the course of work at the computer blinking eyes in humans occurs in about 10-15 times less than with other conventional classroom. Force can not be blinking continuously, so a more realistic way out will be to increase the frequency of interruptions. Another solution - regular use in the process drops that prevent corneal drying.

There are a number of differences screen and natural images. Thus, the screen is always self-luminous, it has much less contrast while still decreasing due to light from the outside. In addition, the monitor image is not continuous: it consists of pixels - discrete points. This image, moreover, has no clear boundaries, as the difference of brightness of the pixels is smooth.

In the process, people are constantly moving eyes from the keyboard to the screen, and sometimes on a piece of paper. Consequently, the load on the eyes is greatly increased. This may aggravate the situation and properly organized workplace. It is important that the distance from the screen to the eye was correct, you must select the optimal brightness of the screen, to prevent ingress of glare from other sources on the monitor and others.

No less dangerous and constant static posture that is maintained during the operation, and continuously repeated movements. As a result, a person may eventually suffer from disorders of the musculoskeletal system. So, cervical osteochondrosis   manifested by headaches, sometimes a throbbing sore eyes , Blurred vision, the appearance of bright circles and "tingling" in front of his eyes.

The monitor, which is not a model of modern technology, may also adversely affect the person working for him for a long time. An additional risk factor for the emergence of computer syndrome is the presence of a large number of computers and other electrical appliances in the room.

Symptoms of computer syndrome

Basically symptoms of computer syndrome occur in people who work in the main part of the day spend on the computer monitor. All complaints are conventionally divided into symptoms " visual "And" eye ".

Visual symptoms   imply constant blurred vision, which leads to an overall reduction of its severity. When you look at things a person can see them forking, it is very difficult to re-focus vision on the subject at the distance, and vice versa. While reading the patient feels tired very quickly. The image and the letters on the screen start to blur.

Eye symptoms involve a burning sensation in the eyes, feeling the appearance of grains of sand under the eyelids, pain around the eye sockets and forehead. Patient blush eyeballs, he feels pain during their movement. Sometimes patients suffering from computer visual syndrome, argue that the sensations are similar to burning of the eyes. All these symptoms are not constant: they can be combined in different ways, but always occur after prolonged sitting at the computer. If the patient is, for example, in the open air, such complaints virtually not occur.

This phenomenon is sometimes referred to by the term " asthenopia ", Which literally means" lack of power ".

All these complaints to a certain extent we have the majority of people who regularly work for a computer monitor. However, their severity and frequency of symptoms are directly dependent on how long the person using the monitor without pauses, as well as the nature of his work. So, part of computer users say the emergence of such symptoms after two hours of sitting behind the monitor. Most of the people are manifestations of notes in four hours. After six hours of sitting behind a computer screen, these symptoms are already present in every person.

In less strain on the eyes is shown in the process of reading texts on the screen. Stronger load occurs when entering text. High level general fatigue   provoking work in a dialogue mode. When working with computer graphics there is a special type of stress on the human eye.

Already at the beginning of the active introduction of personal computers in the life and work of human specialists, ophthalmologists worked to find the objective of the changes in people who spend a lot of time on the PC. Initially, it was that they often recorded Bole disease cataracts   and glaucoma . But as a result of a more thorough studies of this theory has not been confirmed. Today it is known that the organic pathology human eyes do not arise as a consequence of a long stay behind a computer screen. A negative result in computer operation can only be the appearance of shortsightedness   or progression of myopia, which was diagnosed in a patient previously. Also, some people may be a manifestation of temporary nearsightedness, also called myopia false. In addition to this illness in people, many working at the computer, may be shifting the equilibrium eye muscles, reduced contrast sensitivity of view, there are also other functional disorders. These diseases occur not only in the active computer users, but also for people whose work involves hand-busy.

It will be appreciated by the fact that in recent years, personal computers have been very significantly upgraded and functional and structural standpoint. Accordingly, it is constantly working on the filter screen, protecting people from electrostatic and electromagnetic fields. However, the positive changes are not made less urgent problem of adverse changes in the health of the person operating the computer.

As a result, a user who regularly works behind a computer screen, and increases sensitivity to other works, in which a high level of eyestrain. This is driving a car, working with numbers, etc.

Complications of computer syndrome

As apparent complications of this condition very often have complaints of chronic headaches, a noticeable drop in visual acuity, myopia progression. Sometimes there is also a man cyclospasm   provided a computer malfunction.

Complications of computer syndrome can become a variety of diseases of the spine, manifested as a consequence of misuse and prolonged sitting posture in uniform. These diseases significantly disrupt many body systems. As a result, a person can manifest the disorder of the nervous system, problems with the musculoskeletal system, digestive system, respiratory, circulatory system.

Diagnosis of computer syndrome

Diagnosing this condition a person may be an expert ophthalmologist. Initially, it is important to carefully collect the history, after which a check of visual acuity during the reading and the distance. If the patient has enlarged pupil, carried out the identification of signs of spasm of accommodation. It is also necessary to conduct a survey eye days and the patient, determining the condition remains visual nerve   and retina .

If a person complains about the presence of dry eye, he carried out the so-called Schirmer test, by which to estimate the amount of tear fluid. In some cases, you must also assess the quality of tears.

The treatment of computer syndrome

Treatment of the syndrome computer, primarily involves organizing mandatory breaks during operation. Also, as the treatment of this condition used the appointment of special glasses, eye drops.

Such drugs are usually harmless and do not cause allergic reactions. It is important to bear in mind that these drugs can be used not more eight to ten times each day. Drugs which influence is the moisture in the cornea are different in their degree of viscosity. To ensure prevention of computer vision syndrome, you can apply a drop having a low level of viscosity. At the same time are suitable for oral drugs that improve the function of vision. There are some tools that are based on the components of the blueberry, which contribute to improving vision, and strengthen the walls of blood vessels, act as antioxidants Protecting from the harmful effects of free radicals.

If in the course of work in front of a computer monitor in a human manifested swelling eyelids, irritation and redness, then as a drug suitable decongestants.

How to protect yourself from computer syndrome?

There is no doubt that modern life is impossible without the regular use of a personal computer. However, in order to prevent symptoms of computer vision syndrome is necessary if possible to reduce all the work behind the screen of the monitor to a minimum and to establish a rule to make regular breaks in small dynamic static working at the computer.

However, it does not always have the opportunity to minimize the process of staying in front of a computer monitor.

Therefore, it is important to ensure the prevention of computer syndrome manifestations in different directions. First of all, as far as possible is important to improve the image on the monitor, as close to its natural. For this purpose, optimization of the main parameters of the monitor image. In addition, it is desirable to operate at Bole modern monitor because developers are constantly introducing new ideas concerning the protection of the user from the negative effects of the PC.

A very important factor in the prevention of computer syndrome manifestations is the right approach to workplace rights and ensure rational regime of work at the computer. To work best, sitting in a special anatomical seat and the distance from the screen to the human person must be at least thirty centimeters. Ideally, this distance should be between 50 to 70 cm. The center of the screen at the same time should be placed 10-15 cm lower than eye level of the working person.

It is imperative to comply with the conditions for children and adolescents, as too much strain on the eyes when not yet formed a manifestation of refraction can cause myopia.

Another important point - the need to adjust his eyes to the monitor. For example, there are special glasses that are equipped with progressive lenses, allowing to change the features of perception of the image on the display.

Points, which are computer spectral filter, allow us to make more contrast and clear image on the retina of the eye, enhance contrast and color discrimination, block electromagnetic radiation. Using the glasses can not only relieve fatigue and irritability, but also significantly reduce the number of mistakes that a man working on the computer performs in the afternoon.

In the course of work at the computer to facilitate state can be instilled into the eyes periodically special drops to help relieve eye fatigue. This medication oftagel . sisteyn . Vidisik   and others.

Gymnastics for the prevention of computer syndrome

During breaks at work to be done every forty minutes, you can periodically perform exercises special exercises that strengthen the muscles of the eyes.

To perform the first exercise you should close your eyes and feel how tense eye muscles. Further view should be slowly moved to the left, then right, as far as possible. Exercise is repeated ten times.

For the second exercise should be very narrow eyes and stretch the muscles of the face and neck. Breathing should be delayed for 10 seconds, not relaxing. Then follows a quick breath, opened his eyes wide and mouth. When you repeat the exercise five times, it will help to relax your eyes and enhance blood flow.

For the third exercise should be put on eyelids fingertips and make ten times as fast, but the light massage movements. This eye muscles beneath his fingers felt they should not. This is followed by a rest with your eyes closed and repeat the massage twice.

To perform the fourth exercise, you need to sit near the window and put her hand over his left eye. Holding a pencil in his right hand, you need to place it near the tip of the nose. Followed by moving the pencil, gently moving it at arm's length while looking at him right eye. Then you need to look at a distant object to translate the window, and then look at a closer object. Concluding the exercise, you need to look at the tip of the nose. All this should be repeated for both eyes.
