Computer damage to eyes. Does a computer ruin your eyesight? Eye drops for computer eye fatigue

Good day. Today we will talk about how computers can harm your eyes.

And so, my first two articles, dedicated to maintaining your health in connection with sitting at the computer, were about.

This same article, as I promised, will be a continuation of the begun series, well, what will be discussed, you probably already understood from the title.

Let's get started.

Introduction to harm to your vision

The quality of life directly depends on the state of your eyes, because it is through them that we receive up to 90% of information about the world, and psychologists believe that a person with impaired vision will always be subconsciously dissatisfied with something.

Computers appeared in our lives quite recently and so far, even for several decades, human body Still, he did not have time to adapt to their harmful society. The fact is that our visual analyzer (wow! what a word I know! :D) initially not prepared to view the image on the monitor screen. We are accustomed to “stable” information carriers, such as paper, where the image is made up of continuous lines, or the world around us, consisting of dense, non-luminous objects.

With a computer, everything is different: the picture on the monitor consists of thousands of luminous dots and they glow with the intensity of a table lamp, so staring at the monitor is almost the same as continuously looking at a lit chandelier.

But that’s not all: the range of brightness between the image on the screen and surrounding objects exceeds the reasonable limit for which our vision is potentially ready, i.e. the harm of the computer in this regard is obvious.

The nature of the work also makes its contribution: if you constantly run your eyes from the monitor to the keyboard, then the pupil does not have time to expand; if you periodically look outside the window, narrow your vision. Blood vessels burst from tension, the eyelids become heavy, the eyes burn, ripples, fog, impaired color perception, and sometimes double vision of objects appear.

Doctors call such phenomena a syndrome computer vision, or asthenopia, which literally means tiredness visual analyzer. Do you recognize yourself? Congratulations, you are already on the “right” path! To get a bouquet of these symptoms, it is enough not to look up from the monitor for the entire two or three hours, and after seven to eight hours a state of stunning will appear, your appetite will disappear, objects further than half a meter may begin to flicker, the back of the head will become numb and, possibly, begin to feel nauseous. Have you still not thrown your monitor out the window and are reading this article further?

Computer technology has become an integral part of life modern people. According to research, the average person spends up to 3.5 months a year in front of a TV or monitor screen. That is why it is important to know how a computer affects vision in order to take timely protective measures and keep your eyes healthy.

Symptoms of the negative impact of computers on human vision

Consequences long work behind the monitor they often become:

discomfort and irritation of the eyes,
feeling of “sand” in the eyes,
burning and pain in the eyes.

Such symptoms are usually called “computer vision syndrome”, or “monitor syndrome”. It is often accompanied by “dry eye syndrome”.

The eye muscles begin to tire from the constant strain from the computer, which causes eye pain and spasms. Normally, a person should blink every 5 seconds, that is, about 11,000 times a day. But while we are intently looking at the monitor, our eyelids close 5 times less often, since we have to strain our eyes to see the constantly flickering image. Basically, the computer spoils vision for this reason. However, there are others negative factors, the influence of which should be taken into account when considering the question of how to preserve vision when working at a computer.

Why does your eyesight deteriorate when working at a computer?

Eye strain. If you compare a printed image and a picture on the screen, you will notice that in the first case it consists of continuous lines, and in the second - of individual pixel dots that constantly glow and flicker. The longer we work in front of a monitor, the more our vision deteriorates from the computer. However, different activities cause different amounts of damage to our eyes. Thus, when reading or drawing, the load exerted is 5 times greater than that experienced by our visual apparatus when watching a film, even if we are at a fairly close distance from the screen. This is due to the fact that in the first case our eyes focus on one point for a long time. It is this concentration that has a negative effect, increasing tension in the eye muscles. Therefore, many people experience eye pain when working at a computer, which ultimately damages their vision.

Organization of the workplace. If you notice that your eyes hurt and get tired from the computer, pay attention to its location. Visual discomfort can be caused by insufficient lighting in the workplace, glare on the screen, or incorrectly configured monitor settings (for example, very high brightness or insufficient contrast).

Uncomfortable presentation of information. The influence of a computer on human vision is determined by the quality of the image on the monitor. It lacks the contrast and clarity our eyes are accustomed to that printing on paper can provide. Focusing and holding our gaze on such images visual apparatus is more difficult than when reading. Also, severe fatigue and eye fatigue can be caused by an inconvenient computer interface. Poor fonts, colors, and layout are bad for your eyesight and can cause headaches.

How to preserve your eyesight when working at a computer?

Protecting your eyes from the negative influence of a computer is a feasible task. To prevent computer vision syndrome when working on a monitor, follow following tips:

Blink more often. One of the causes of dry eyes is insufficient blinking. We often look from the monitor to the keyboard. At the same time, our brain perceives this movement of the eyelids as blinking. However, since the eyes do not close completely, they do not receive sufficient hydration and cleansing from microparticles that have fallen on their surface. Therefore, try to blink more often to increase your chances of maintaining your vision while using the computer. If you wear glasses or contacts, your eyes may also need extra moisture. For this you can use special drops, the composition of which is similar to human tears.

Use computer glasses. They are designed to increase image contrast and eliminate glare. The lenses of high-quality computer glasses must contain special filters that do not transmit blue light emitted by the monitor screen. Such rays can damage the retina of the eye, causing blurred vision. The presence of such a filter is indicated by a brownish tint to the lenses. In addition, their surface must contain anti-reflective coating. To be sure that glasses will help you maintain your vision at the computer, consult an ophthalmologist to select them.

Install the monitor correctly. The screen should not be located opposite a window without curtains. This contributes to the appearance of a difference between the brightness of the monitor and the space behind it, which causes visual discomfort, contributes to fatigue, eye strain and computer headaches. The direction you look also matters. You can protect your eyes and reduce the negative impact of the computer by positioning the monitor so that it is 10 cm above eye level.

If you follow these simple tips, your eyes and computer will be able to coexist together, and you will see life 100%!

Take breaks. To make your eyes less tired, it is advisable to look away from the computer monitor for at least 30 seconds every 20 minutes. This time can be devoted to light gymnastics, or perform a small set of exercises to relax the eyes.

Gymnastics for the eyes

Exercise 1. Place your gaze on the bridge of your nose and stay in this position for 4 seconds. Then look at the landscape outside the window (about 6 seconds). Repeat the exercise 4-5 times.

Exercise 2. Look to the left as far as possible, provided that you cannot turn your head. Fix your gaze for about 4 seconds. Do the same exercise, looking left, down and up. Repeat 3-4 times.

Exercise 3. “Draw” a circle with your gaze counterclockwise, then look straight into the distance out the window. After this, “draw” a circle in reverse side. Repeat 3-4 times.

Exercise 4. Blink as quickly as possible, counting to 10, then close your eyes for a couple of seconds. Now blink again for a minute. Close your eyes again for 2-3 seconds. Open them and look out the window into the distance. Repeat the eye exercise 2-3 times.

The human eye is by nature a mobile organ. The process of accommodation continuously occurs in them, that is, switching the gaze from distant objects to near ones. This allows a person to navigate in space. The eyelids move in the same way. A person blinks approximately 20-25 times per minute.

Blinking keeps the surface of the eyes moist. When a person stops blinking, the mucous membrane dries out and an unpleasant burning sensation appears. And in principle, a person rarely looks at one point, preferring "slide" glance at the world around us.

Achievements of science and technology, of course, make human life easier and more interesting, but at the same time they cause significant harm to health. Vision has suffered significant damage with the development of computer technology. It is difficult to imagine a modern person without a computer. We read from monitors, watch movies, type texts and watch the news.

Everyone who works at a computer has at least once noticed how tired their eyes are at the end of the working day. A characteristic burning sensation appears, a certain sensation "broken glass" In eyes. The blood vessels burst, leading to redness and a headache. All this happens due to eye strain. By looking at one point for a long time and continuously, we deprive the eyes of accommodation movements. We do not move our gaze around us. Lateral vision is blurred. And we stop blinking.

When working at a computer, the frequency of blinking decreases by five times. By looking from the keyboard to the monitor, we imitate blinking. Eyes close, receiving certain part moisturizing, but this movement is not enough. All these negative points are also present when reading books or writing, but very important point is that the book is a solid text with constant brightness of the pages and solid lines.

A computer monitor consists of thousands of small luminous dots. They all flicker. We don't realize it, but it makes things more difficult for our eyes. When reading or typing, we do not take our eyes off and move it as much as possible from side to side. This is an unnatural movement for the eye. Therefore, reading from a monitor is the most harmful process.

Even watching a movie is less harmful to health. In addition, the monitor is surrounded electromagnetic field. Charged dust particles, of course, interact with the human body, and the fact that they negatively affect the body as a whole has not yet been proven, but the damage to vision is obvious. These dust particles settle on the cornea of the eye, irritating the mucous membrane. Damage to the eyes can be caused by incorrectly set monitor brightness, image contrast, too small or pale font, too colorful pictures that you have to look closely at.

Too bright light from the screen will cause painful sensations In eyes. A blurry image will cause the already overstrained eye muscles to strain even more. In addition, the eyes, like any other organ, develop a certain habit. Constantly spending time at the computer, they lose the habit of seeing what is on the side. They get used to focusing on the image that is straight ahead, ignoring peripheral vision. A person begins to see unidirectionally. Vision is three-dimensional in nature, but looking at the monitor we see only a two-dimensional picture.

As can be seen from all of the above, interaction with a computer is not normal process for our vision. Everything that happens when working with a monitor is unnatural and harms physiological data. human eyes. However, vision is spoiled by books, writing, and performing complex small tasks (for example, needlework). People do not refuse these processes. Vast generations of experience have been accumulated in preserving eye health.

The same should be done with computers. Stop interacting with screens to modern man impossible, which means you need to accustom yourself to observing simple visual hygiene. It is quite possible to devote very little time to eye health and avoid the negative effects of the monitor.

The simplest methods for maintaining eye health when working at a computer

Gymnastics for the eyes

The old and familiar recommendation of ophthalmologists to do eye exercises is ignored even by professional programmers, who are more susceptible to negative influence computer. In fact, everything is very simple. Eye movements are provided by the same muscles as all other muscles in our body. And why are we not too lazy to go to GYM's and pump up your abs, but we can’t devote very little time to maintaining eye health?

Muscles get used to the same type of movements, which are much smaller than what nature intended. Vision becomes unfocused. By doing exercises once a day that will force the eye muscles to perform the necessary movements, we will prevent negative habits from forming and entering everyday life.

Force your eyes to carry out the natural movement of accommodation. Look very close (for example, at the bridge of your nose) for four seconds. Then look far away (preferably out the window). And look into the distance for another six seconds. By repeating this exercise five times, you will stretch your eye muscles.

Make circular movements with your eyes. After twisting in one direction, stop and look into the distance. Then turn your gaze in the other direction.

Move your gaze far to the side. As much as you can. Then sideways and down. Then sideways and up.

Alternate between blinking quickly, relaxing (closing your eyes) and looking into the distance. Repeat this several times.

The problem of children's addiction to computers is very acute. From the early age kids know how to use computers. They mostly resort to games.

Even if the games are active, the child focuses on the image, peers at the screen, strains his vision and it deteriorates. Why is it more harmful for children to sit at the computer for a long time than for adults?

Everything is very simple. Their muscles are not strong enough, and their skills are formed very quickly. Eye muscles quickly unlearn looking into the distance and the child will develop myopia. Lateral vision will be significantly impaired.

He should sit at a distance of 70 cm from the monitor, on a comfortable chair, so as not to damage the spine, and spend no more than an hour a day at the computer. If such rules have not been followed before, do not despair. Children's vision You can quickly restore it, just eliminate negative influence factors, and do the simplest eye exercises described above.

I am often asked the question: is a computer harmful to humans? Since I love the computer very much, and I can’t even imagine my life without it, it just offends me when such a miracle technology is blamed for all the troubles. Once in the hospital, at an appointment with a neurologist, I saw a woman who was telling her friend that the computer had caused her to become disabled. From the conversation, I realized that she simply hates her job, and in particular the computer. A friend of hers, apparently, had never worked on a computer at all, and with every phrase her friend said, she made everything even worse big eyes, and by the end of the conversation, I was one hundred percent sure that the computer is evil!

But the most interesting thing is that the woman who talked about all these horrors looked blooming. And then I learned from the nurse that she was not sick at all. He just doesn’t like to work, and is looking for a thousand ways to take sick leave. This is how myths are born. But let's still look at some of them. I will not convince anyone of anything. You will draw your own conclusions.

How harmful is a modern computer? I deliberately emphasized the word modern. What is meant by a modern computer? A modern computer is primarily a liquid crystal monitor. It is to him that there are most complaints, and then to his information.

Myth 1. The computer is very harmful to the eyes

An LCD monitor is no more harmful than a plasma TV. It doesn't have a cathode ray tube, which sticks out at the back like the muzzle of a tank, encased in a bulky casing. Exactly rear end monitor and was the most dangerous, because all radiation came from the back.

If you still use such a monitor, install it so that the back of it does not face people.

The front part of the monitor also did not add health to our eyes, because... the image was not very sharp, and over time it became completely blurry. The phosphor that covered all the screens of cathode-ray devices faded over time, and the picture lost its clarity, which was already not up to par.

The screen refresh rate on older devices jumped noticeably to the eye. Many users did not know that it had to be constantly configured. This seemingly imperceptible flickering caused people who worked at the computer for a long time to have their eyesight deteriorate quite quickly. And hence the headaches and the whole “bouquet” concomitant diseases. In severe cases, it even reached the point of disability.

It is not the monitor that is harmful, but we ourselves “damage” our vision. The fact is that we constantly blink, unnoticed by ourselves, and this is how our eyes are lubricated. And when we sit in front of the monitor screen, our eyes dry out, because... I don’t know why, our body forgets about lubrication, and we simply don’t blink.

Constantly focusing our eyes at a close distance is also harmful. That is why it is necessary to look away from the monitor screen as often as possible.

Myth 2. The spine is curved and the hands hurt

Well, in this case it’s clear that the computer has nothing to do with it. I myself often notice that from sitting for a long time behind this miracle technique, I just start to crouch.

Firstly, workplace should be comfortable.

The table should be no higher than chest level and wide. Computer desks with pull-out shelves for the keyboard and mouse are only good if you have a comfortable chair with armrests.

Hands should not hang in the air. Otherwise, over time, you will develop a disease called “tunnel” syndrome. I have already experienced for myself what it is. God forbid anyone. First, your hands will begin to go numb, and then at one fine moment, among full health, your hand, which you always use to hold the mouse, will simply stop working.

You won't be able to hold anything to her, not even your favorite mouse. On top of everything else, severe pain in the wrist. Every movement you make, even with a finger of this hand, will cause you incredible pain. It is better not to let this happen, otherwise you may become disabled.

I even changed my desk to a regular one at work, because... hands should lie on the table and not hang in the air, and chairs with armrests are not always comfortable.

It is very important that your back rests on the back of the chair or chair. IN as a last resort put a pillow behind your back.

And most importantly, don’t be lazy to get up once an hour and do a little exercise for your arms and back. I know that laziness and time flies quickly and unnoticed, but MUST! Otherwise, very soon your muscles will become flabby, and you will also suffer from back and lower back pain.

Eat special programs for the computer, which through certain time I block work, the monitor goes out or a message appears that it’s time to rest. Install one for yourself. Useful thing! I use this myself, otherwise there’s no stopping me.

Myth 3. A man working at a computer becomes irritable

If your computer is noisy, don't ignore it. Be sure to call a specialist or find out what it is and fix it yourself. Even seemingly imperceptible noise over time leads to headaches and irritability.

And I want to repeat once again, the harm from a modern computer is no more than from a plasma TV. Follow these few rules and no harm will happen.

It is not the computer that is to blame for all our illnesses, but ourselves.

Myth 4. The computer corrupts and brutalizes youth

I fundamentally disagree with this. Looking at my daughter, who also became a programmer, I can say that this is complete nonsense. I never forbade her from visiting any sites on the Internet, but I controlled where she was. Then, on occasion, I started a conversation with her on a topic that interested her on the Internet.

Thus, I found out what she thought about this, and within certain limits expressed my point of view on this issue. Therefore, she never hid anything from me, but on the contrary, she asked if there was something she didn’t understand.

But, mainly, I tried to captivate her with sites on the right topic, where she could develop in the right direction.

I always played computer games with her. More precisely, I watched her play. Even now, she and I sometimes sit down at the computer and spend the whole day, or even night, “hanging out” in some game.

It’s not the computer and the Internet that are harmful, but it’s our own fault that we’re mired in our own worries and don’t see what worries our children, what they breathe.

Based on the behavior of my daughter’s friend in an online game, for example, I realized that it was better for him to go not to law school, as his parents wanted, but to an institute related to finance. Oddly enough, they listened to me, and the guy began good specialist in the bank. Before that, he worked part-time as a store manager. So the store director was shocked by him. He has never had such a turnover. The guy fulfilled the six-month requirement in a month.

At least today, forget about all your business and play some computer game with your child. Just look at how skillfully he plays. It is through games that you can determine your inclinations (which is important for future profession), experiences or complexes of your child. And most importantly, you will become closer and dearer to him.

Don't forbid him to play, but play with him. And then you will see for yourself that the computer is not only harmless, but, on the contrary, useful. The main thing is for you to set the right direction in its use. Do not think that a computer is created only for work and study. A child's development begins with toys and games.

And our life is essentially the same computer game. Our every action determines whether we will move to another level or GAME OVER.

I often have to post my videos on computer topics on YouTube. Mostly young people are interested in this topic. So, from the comments to my videos, I can judge that young people on the Internet are quite adequate and pleasant guys to talk to.

It very rarely happens that some guy will write something nasty and vulgar. Most likely, these are unrecognized, deeply unhappy and angry people. By the way, most often it is not young people who write nasty things, but already formed individuals.

Therefore, drawing conclusions about whether the computer, and in particular the Internet, is harmful for young people, based on several facts, is just as wrong as generalizing data on mental illness. If there are several dozen psychopaths in a mental hospital, this does not mean that the whole city is like that.

Everything is good in moderation. If you follow the rules of working with a computer, and do not forget about real life And physical exercise, then the computer will not be harmful to your health.
