It is difficult to find a family in which there would not be a computer. But not every family can boast of their own living space, where there is a separate children’s room and a separate room to work. From this follows that from an early age children are accustomed to seeing their parents at “miracle machine” with enthusiasm, their eyes are staring into the monitor and constantly crawl the mouse on the desk. All this, in turn, leads to an irresistible interest in children to the computer, keyboard, mouse, disks, – in short, everything that is connected to a computer. There is a big question – what to do with the problem of ‘children and a computer? ‘ We will try to find out!

Remember that if you taught the kid to watch on your computer only development programs and cartoons your children and your computer will find no more “intimate contact” at school age – that’s impossible! A child with each subsequent day will occur at the beginning of interest to movies, then to the Internet, and then to the more spicy things, with which Internet is full! All of this will leave plenty of time, the child will become couch potato, gambling, and most memorable moments of his childhood with the boys will not in the yard with the ball and sleds, but in front of the monitor.

Let’s start in order:

1. Internet – this is primarily an enormous amount of useful information! Look at yourself, you are currently using this tool to find the right knowledge. Therefore, until a certain age, parents need to filter the flow of information from the network and files on your computer;

2. Games – the attribute, without which the computer is not available. There are plenty of interesting games to play. It should be clear to distinguish between necessary and brutal, vulgar, stupid games. Do not succumb to the entreaties of the child to buy what he wants. If the child has already learned to install the game himself – remove unnecessary content filter on your computer. Now a lot of games that are designed for kids from four years – they develop logic, taught reading, writing and mathematics. This may be good games related with travel and fairy tales. And there are all sorts of “Shooter”, where is a lot of blood.

3. Movies – this is at the discretion of the parents, again, constantly filtering and checking the contents of your computer. However, until a certain age, let it be a cartoon;

From an early age children need to program that computer is the thing for school, work, this is the correct thing! If the child is already quite an adult, is going to school – meet him with interesting sites about animals, plants, historical, and technical subjects.

These days, when computers are used everywhere, having a computer is a must. There exist different brands to select from. Those who are considering buying HP, might be interested in looking through this hp envy 14 review which can be found on review hp envy 14 site. Should the model be of any interest it is recommended to read some more hp envy 14 reviews to compare the laptop with others and make a balanced decision.

Children living in the modern world often replace the interaction with friends, playing sports, outdoor games in spare time, walks in the fresh air with a computer. It is difficult to deny that the computer allows the child to develop, obtain information, communicate … However, many parents are unaware that many hours sitting at a computer can cause a computer’s syndrome, which is expressed in a spasm of accommodation – long-term static strain, and dry eye syndrome, arising from the drying surface of the cornea from a rare and blink continuously looking at the object of work.

In the course of communication with the computer kids have to solve increasingly complex spatial and gradually logic puzzles that require considerable mental and eyestrain, since the relatively short distance we have to consider the on-screen small letters, pictures, numbers, dashes. Periodically glancing from screen to keyboard the child constantly re-makes accommodation of the eye. This causes stress the eye muscles which increases light pulsing screen. Thus, the load on the eyes when communicating with a computer is very different from other types of load at visual work – reading, for example, or even watching TV.

Another important factor is the neuro-emotional stress. It’s no secret that communication with the computer, especially with game programs, is accompanied by a strong nervous tension, because it requires a quick response. Short-term concentration of nervous processes is clearly a child’s fatigue. Working on the computer he experiences a kind of emotional stress.

A sitting position increases the statistical burden and lowers the already low, the motor activity of the modern child. As a result of the long seat in a fixed position, pain in the muscles of the neck, back, headaches, aching joints of the hands can cause various diseases of the locomotor system. Prolonged constrained posture makes it difficult to breath.

Statistics show that even work at a computer for 1-2 hours causes 73% of adolescents overall and visual fatigue, while the usual training sessions fatigue occurs only in 54% of children. Often, fascinated by computer games, kids do not notice the fatigue which then strongly affects their vision. Fatigue, distraction of attention, anxiety begin to appear in children after a 15-minute work on the computer, and after 20 minutes in 25% of children were reported by experts from the unpleasant effects of the visual apparatus and the central nervous system.

Accident prevention

Prevent the appearance of fatigue is possible. To do so limit the duration of the child spending time at the computer, regularly do exercises for the eyes, organize the workplace, use only high quality computer programs relevant to their age, ventilate the room where the computer after each hour of work.

Influence on computer vision, in addition, can be reduced by buying a good modern monitor with high resolution and high image refresh rate which significantly reduces the flicker. The optimum screen size for your baby is 15 inches, for a student you can buy 17-inch monitor.

The correct distance to the monitor is about 45-60 cm, preferably at eye level, the right lighting – natural light falling on the left and in the dark – the lamp should illuminate only the document you are working with the child, not the screen, to avoid glare, complicating the work.

Many parents are unaware of the existence of the norms established by the Ministry of Health to use your children’s computer. These norms are very strict but objective. For first time at the computer should not exceed 10 minutes per day, only 15 minutes is recommended by child. High school students require no more than 30 minutes of continuous work at the computer for the first hour of lessons and 20 minutes on the second. Safe standard of computer games that are so fond of modern teenagers is 10 minutes for children and for junior high school students – 15 minutes. In addition, computer games before bedtime are strictly prohibited.

In order to reduce the harmful effects of awkward postures it is necessary to choose the right furniture workers. A specialized children’s furniture will help to reduce stress and maintain the correct position when working at the computer. Chair on castors, with height and tilt adjustable backrest, without armrests, rotating around its axis. Table – with a special pull-out board for the keyboard.
IMPORTANT!

*
In the room with a working computer the physical characteristics of the air changes: the temperature can rise to 26-27 degrees, relative humidity – to fall below normal (40-60%) and carbon dioxide – to increase. The air is ionized, the number of positive (heavy) ions, which adversely affects the performance. Some people, including children are particularly sensitive and painful to react to these changes in the air. They have a scratchy throat, cough due to increased dryness of mucous.
*
Do not forget the high-frequency electromagnetic fields which create a deflecting electromagnetic system monitor. Be careful: in modern models such radiation is most strongly from behind and above the monitor and the front slightly. So you cannot lean over the monitor, put it best back wall to the wall.
*
The computer can create an electrostatic field of high tension, which acts as a time at a distance of two feet from the screen. The modern monitors have special filters that reduce the intensity of the radiation. Air conditioners, dust collectors, ionizers, dry cleaning and room ventilation reduce the harmful effects of the electrostatic field. It is also effective washing with cold water immediately after training on the computer.

The human eye formed during the long evolution in the twentieth century was not well suited for use with a computer image. The picture screen is different from the natural fact that it is luminescent and not reflected. The visual load increases significantly because of the need to constantly move the eyes from the monitor screen to the keyboard and paper text. Often the inability to correctly and efficiently organize the workplace (the glare on the monitor screen from external sources, improper distance from the eyes to the screen, an unfortunate choice of colors, too much brightness) aggravate the situation.

The greatest common causes fatigue work online. A special eye strain is a computer graphics – the implementation and adjustment of working drawings from a PC. At risk of “computer syndrome” are active computer users aged 18 to 40 years.
The symptoms of computer eye syndrome

Complaints of people spend most of their time behind the screen of the monitor can be divided into two groups:

- Optical

*
blurred vision (blurred vision);
*
slow refocusing from near objects to far and vice versa (disturbance of accommodation);
*
doubling of objects;
*
rapid fatigue when reading.

- Physical

*
burning eyes;
*
feeling of “sand” under the eyelids;
*
pain in the eye sockets and forehead;
*
pain when moving eyes;
*
red eyeballs.

The study of visual functions in humans for several years worked for the PC found the decline in accommodation compared with age-related norm and a greater frequency of myopia compared with those of the same age, not related to the computer. Individuals placed on the above complaints, all of these changes were more pronounced. Investigation of the effect of the work itself with a display on the eyes showed that per shift is a reduction of the amount of accommodation, and some users have developed a temporary, “false” short-sightedness.
Recommendations to combat “computer syndrome”

Do not neglect a visit to an ophthalmologist and not self-medicate.
*
Use special eye drops, tear replacement
*
Limit the time of the computer no more than 4 hours per day
*
Do mandatory breaks during the work at close range every 20-30 minutes.

There are special glasses with progressive lenses which correspond to the zone of clear vision eye movement while working at various distances. The use of it gives reduced visual fatigue and improvement of accommodation compared with conventional glasses to 85% of workers.

Subject to these recommendations reduced the number of errors committed by the operator, especially in the afternoon. The glasses are comfortably in the street, under a cloudy sky – clearly visible and contrast, and on a sunny day they do not pass into the eyes of a very active part of the shortwave spectrum. Thus, glasses with a computer filter can be recommended for continuous wear. And it is very important because over 50% of computer users are people with glasses.

If you consider yourself a full-fledged citizen of the modern world, then surely you could not help noticing an accelerated rate of development of electronic industry in the last 20 years. First and foremost this is due to the rapid technological and scientific progress in the world. For the simple townsfolk turned these changes the appearance of a large number of electronic technology in everyday life. For example, each person can find a home microwave oven, refrigerator, TV, washing machine and other useful devices, not to mention such trifles as a hair dryer, electric razor, that even drying shoe that consumes electricity. In just a short time our flats are transformed from a zone of peace and comfort in the concrete chambers with elevated levels of electromagnetic radiation. But to escape from an overabundance of EMI is hardly possible in the workplace, because according to statistics, about 30% of the population most of the time spend working at the computer.

Harm of your computer

And it is about the dangers of the computer I want to talk now. Controversy on this subject has been going on for quite a long time, actually since the first models of personal digital assistants. Currently, there are at least three major types of computer effects on humans.

* The first of them is a violation of the functioning of some systems of the body due to sedentary work (after all, with the advent of the PC number of movements of office workers has decreased by 2 – 4 times). This is significantly affected locomotor, muscular, circulatory systems, etc. But to accuse of violating the functioning of the body because of reduced mobility of electronic computers is hardly a sensible idea, since in this case the PC – this is only an indirect cause.
* The following type of impact is the concentration of attention by the user on the screen during the extended period of time, that is, harm your computer may appear in different aspects of the visual system. But this case also only indirectly indicates danger to the health of your PC.
* The third and last type of interaction between computers and humans is in harmful electromagnetic radiation, which, according to recent research in this area may be one of the hazards to human health. Although in the past 10 years, the manufacturers have significantly reduced the radiation level from the front of the monitor, but still remain side and rear panels, as well as the system unit, power, and the working frequency of which is constantly increasing, and consequently increase the level of dangerous high-frequency electromagnetic radiation.

From the above we can conclude that the producers make statements such as: damage to your computer is unsubstantiated fiction, you must be careful with this electronic device, or it may jeopardize your health.
