"Nose to the screen": Can the TV screen or monitor ruin your eyesight? Bashny.Net

Explanation of professional oftalmologa

We have repeatedly written on this subject, and every time is a matter of heated debate: some knowledge enter into a dispute with certain assumptions, and the truth is still far away. We arrange dot the "i": Can a computer monitor or TV screen actually "plant" your vision and trigger the development of myopia (nearsightedness)?

Says ophthalmologist, a medical advisor «Johnson & Johnson Vision Care in Russia and the CIS", assistant professor of ophthalmology IPK FMBA Irina Leshchenko.

1. The monitor does not spoil vision adults adults from a long and careful scrutiny of the screen does not develop myopia. But there are other risk factors: prolonged work at close range, poor lighting, uncomfortable posture, the load on the neck, short residence time in the fresh air, a small length of daylight.

An interesting point: some people have risk factors fail, others do not. If there is a genetic predisposition to myopia, it will develop and a person who does not watch TV or monitor. But it's more likely to happen to a child.

2. Long working at the computer increases the risk of myopia in children and podrostkovGlaza grow with the rest of the body, from his childhood. Eye Height ends in 18-20 years after myopia hardly progresses. Standard size of the eyeball - 24 mm, and if the eye at least half a millimeter more, it short-sighted.

Today's children are introduced to the computer, they turn a year. Later, at school, they spend the monitors for a few hours: the lessons have to look at the monitor, and a lesson lasts 45 minutes. For homework, too, need a computer. The eyes are constantly tense - and eyeballs a child growing up in the end more than necessary. Why is that, exactly, nobody knows. All theories boil down to the fact that the eye grows to more clearly see objects at close range.

Nothing good about it. Children up to ten years is normal for the screen to carry out 10-15 minutes a day, no more. Teenagers - no more than two or three hours a day. In Russia, one of the leading factors in the development of myopia in children - prolonged sitting "nose to the screen" from an early age.

3. When using a computer, it is important to remember profilaktikeEto applies to children and adults. When one looks into the distance, his eyes relax. When he looks at a near object (monitor, a book), eye strain. So, you need to rest your eyes: do work breaks every 20 minutes, to change the position of the body at the same time, keep your eyes on the monitor or notebook, and at least 20 seconds to look into the distance. This is very important. Well, even some exercise, or better yet walk in the fresh air.

Ideally, in the working room is a window, which can be translated to look and look into the distance, to relax the eyes. Please note: if you sit facing the window, the window on sunny days it is necessary to curtain. At the same time sit facing the window better than the back, because it's rays do not fall on the eyes and the monitor does not have to further tighten. If you can not put the desktop so that the person sitting to the window, put at least sideways.

Look at the screen from the bottom up is impossible, it should be slightly below eye level. In other words, the head should be slightly above the edge of the monitor. It is important to monitor the distance to equal the length of the arm's length, that is 60-70 cm. The board must always be a glass of water: the day you need to drink at least two liters of water. And it is important to blink more often.



4. debunk myths: carrots, gymnastics and eye glasses are not treated blizorukostOchki and lenses only correct the vision. They help myopic eyes to see more clearly: removed the "extra" diopters. The increase in myopia, they will not stop, let alone cure it. And with lenses, particularly those who have a long service life, more must be handled very carefully: take only clean and dry hands and shoot at night.

Gymnastics for the eyes, too, does not recover "stranded" vision. I do it well, because people will come off from work and relax your eyes at least briefly. But the eye of the exercise does not become less.

Regarding blueberries and carrots, they also do not return acuity. Contained in these products are really necessary elements for visual processes but blueberries and carrots - are not the only sources of vitamin A, there are others.

5. As an adult can recover "stranded" zrenieA here laser correction of vision really returns. Young people tend to change shape and thickness of the cornea, and the elderly - are changing the lens. Such operations are generally safe - dangerous methods simply would not have taken root.

Please note that the girls better to have a baby, and then to do this operation because during pregnancy increases the load on the whole body, including the eye.
