Myopia, or, as they call it medical, myopia, - a disease in which the human eye can distinguish between bad images, as well as objects located far away. In this case, the image does not have a certain part of the retina, as shown in the plane located in front of it. Because it is perceived as a blurred, indistinct. This occurs due to a mismatch of the optical power of the eyeball and its length. Usually short-sighted it is enhanced (axial myopia), but the disease can also occur as a result of excessive force refractive apparatus (so-called refractive myopia). The greater the mismatch, the greater the problem.
Today, it is a social and clinical beach, quite common among school - they suffer from almost 12% of children. Basically, the first symptoms of myopia occur at a young age, but over the years the situation is only getting worse.
What causes this disease?
The fact that short-sightedness as a biological concept - an ambiguous phenomenon. Many scientists believe it is not a disease but a normal variant. All cases are united by one feature - the visual setting of the eye. This physical category is characterized by a combination of certain parameters of the human cornea (the length of the anterior-posterior axis of the eye and the lens), the main focus of the optical system is located in front of the retina that is common to all types of myopia. Such features may be due to different reasons.
Aboriginal pathogenetic mechanisms of occurrence of myopia are not well understood, in fact as well as hereditary pathology, intrauterine disease, structural and biochemical transformation of the growth of the body's tissues and the like. Immediate causes, because of which formed myopic refraction, are better known. The main characteristics of the disease are: an increase in the refractive power of the visual apparatus and the eyeball is too large (the exact length) PZO.
How does the disease?
Basically myopia begins with typical complaints. A man falls acuity, the surrounding reality is perceived as a "fog", it becomes difficult to translate gaze from one object located at a short distance to another in the distance (the so-called slow refocusing). Sometimes the patient sees double, often fatigue and strain, there are "creepy" and darkening, acute reaction to light, decreased visual acuity and performance.
Often developing myopia in children of school age. They begin to see distant objects bad, clearly distinguish between numbers and letters written on the blackboard in the classroom, trying to get closer to the screen or the TV in the first place in the cinema. To see something in the distance, near-sighted, usually narrows his eyes. Very often the real myopia begins with a spasm of accommodation (CA), which is the first stage of the axial form of the disease. If the time to identify the symptoms, it can be cured. CA may disappear after passing the optical hardware-physiological and medical treatment, if you reduce the load on the optic nerve, or in the process of growing children.
Myopia phase accommodative spasm characterized in that the eye is still retains a spherical shape, but over time it anteroposterior dimension (i.e. axis) increases, and it becomes elliptical.
At the beginning of the SA expressed slightly, he is said to physicians, the short-lived - it arises and disappears. The kid and his parents may not notice its presence. Emerging temporary blurring of letters and numbers written on the board quickly. Vision improved in the suspension or on the way home from school, so the child does not attach any importance to this and, therefore, does not tell an adult. Consequently, nearsightedness often found already at a later stage, when the duration of accommodation spasm increases from a few hours to a day or two. Change the situation for the better is possible, after a long pause, a night of sleep, during the holidays, that is, in the moments when the eyes a rest. Later, the periodic fall of becoming much more resistant and durable restored vision partially or totally after undergoing special treatment.
The main factors of the appearance of myopia
There are many reasons for myopia. We mention the main ones:
weak sclera which does not have adequate resistance to the rapid growth of the eye;
incorrect landing during operation (a person sits too close to the subject, for example, the child is sitting close to the computer or TV), inadequate lighting, lack of rest;
undeveloped accommodative muscles, responsible for "setting" of the lens at various distances, so that there is over-voltage;
myopia can also develop due to hereditary predisposition;
As you can see, the factors affecting the development of myopia, there are many. However, what is the main one? Why is it sometimes difficult for the same load on the optic nerve in some children manifest the disease, while others - not? Just a weak immune system, in contrast to the strong, not able to fight and "punch". Therefore, as a rule, the disease and appears rather weak people and myopia. Let's look at a few reasons for this state of the human body:
damage to the cervical spinal cord during birth;
chronic diseases of the mouth and throat (e.g., adenoids, sinusitis);
rickets;
a tendency to allergies and infectious diseases such as measles or scarlet fever, tuberculosis, diphtheria and others;
a weak immune system;
disorders of the musculoskeletal system.
All the above factors when too heavy load on the optical system in most cases can cause accommodative spasm, thus, subsequently, if not detected in time symptoms and treatment not just appears and progressive myopia. If a family has a predisposition, it is natural that the process begins much earlier miopizatsii and flows quite rapidly.
What are the categories of myopia?
Ophthalmologists are following myopia:
weak - 3, 0 diopters;
considered changes in the average area of 3, 25-6, 0 diopters;
high - over 6, 0. It can reach significant values (for example: 15, 20 and even 30).
The man, who identified myopia, needs glasses for long distances, and sometimes even for the neighbor. However, unfortunately, they are not always capable enough to correct vision, due to the ongoing changes in the eye membranes.
The disease can be congenital or occur as a result of the negative impact of some of the factors mentioned above. Over the life it is either kept at the same level, or progresses. Myopia be treated, and for this there are special modeling techniques, the main task - so weaken the refractive power of the eye unit, so that the image came from a certain area of the retina.
What to do?
If you think you have nearsightedness (manifested symptoms, doubt, etc.), be sure to consult a doctor. You check visual acuity, appoint suitable glasses, make treatment (average duration in two weeks). There are some methods to combat the disease, as the electrical stimulation of the eyes, bioresonance therapy, optical and physiological massage vizotrening both.
You should be aware that myopia - is not just a violation of the optical apparatus. This "problem" in the whole organism. So, because of the problems of mineral-protein metabolism sclera weakens and eye is stretched at length, thus acquiring the shape of a pear. At the same time it suffers the most posterior part. In severe cases may even detached from the underlying tissue and retinal tears. As a result, there is a real risk of losing all sight.
Also be aware that myopia is a contraindication to certain occupations, requiring that the employee could see. The disease is limited to the household: people suffering from it are prohibited heavy load, lifting heavy weight and so on. Women with this problem give birth naturally can not, as an alternative to physicians offer a cesarean section. So start taking care of your body with the youth. Do not read in poor light, eat properly, to avoid unnecessary stress and injury, and then you will be healthy!

In each case, the cause of acne is to establish a dermatologist. Unfortunately. Almost always people neglect a visit to the doctor. And a very good reason - if not eliminate the root cause of the disease, get rid of acne will be much harder.
Blockage of the mouths of the sebaceous glands and the stagnation of sebum in the duct there are stepping pyogenic bacteria, leading to inflammation.

This means that the skin has accumulated a large amount of sebum itself. And you should only go out as the dust will settle on the skin of the face.
If the morning facial skin will be cleaned, this dust will be much less. And that means, and acne will be much less.

Make sure and water temperature - very moderate washing should be carried out with hot water and finish it must be rinsed with cold water. Hot water to expand the pores, which allow for a more thorough cleansing of the skin. A subsequent rinse with cold water will help narrow the pores, to slaughter them in the dust and dirt.
Diet
Numerous studies significantly demonstrate that the development of acne often depends on what it is man. The most common cause of the problem are the following products:
Any sweets, especially cocoa and chocolate.
