How long have you been working at the computer? Tips for tired eyes

Modern people can not abandon the use of computers - too many spheres of life depend on electronic devices.

But with such a wide penetration of technology in our life there is a downside in the person of the possibility of its negative impact on health and well-being, in particular on the organs of vision.

Eyes can get very tired when working on a personal computer for a long time, what should I do in this case?

How to find a compromise between eye health and the regular use of technical devices? Let's try to understand.

Causes of fatigue

Eye fatigue is a common thing in any work that requires tracking of a lot of small changing objects and concentrating on them.

When reading from paper or embroidering your eyes, too, sooner or later get tired. The problem is that when you work on a computer, this process is faster.

How can this be caused and is this proof of the harm of such work? The most important reason is the decrease in the frequency of morphony.

In the normal state, a person does this about 20 times per minute, which provides the cornea with enough fluids and other nutrients.

And when working at a computer, the blinking takes place no more than 5 times per minute. This is due to the fact that, firstly, the view is turned to the light source, and secondly, it must be constantly concentrated on what is happening on the screen, and similar actions violate this concentration.

Deficiency of fluid and nutrients leads to the fact that the eye wears out much faster. This is exacerbated by the fact that working with the text itself is not simple, and for a drained look it becomes too painful.

Further, the fixation of a glance at one point and prolonged retention of the head in one position leads to muscle spasm and vascular leakage.

In the normal state, the eye constantly changes focus, for example, walking on the street, we look to the right, and to the left, and straight. When working at a computer, there is nothing like that.

In addition, many are sitting with a wrong posture, and some do not even sit, but lie( for example, with a laptop), which also does not work.

We do not exclude the psychological factor. Many people, for whom the computer is not only work, but also leisure, which brings pleasure, almost never complain about problems with the eyes.

For example, gamers. They can play quite a long time without any harmful consequences. It is known and the ability of programmers to work for a very long time without fatigue.

This is due to the fact that programmers, as a rule, enjoy the work, for them programming is not only work, but also leisure.

And office workers who monotonously and without much interest work all day in text editors, face the need to treat the eyes from dryness and overexertion much more often.

The same can be said about schoolchildren and students who have to read a lot of books on the PC or tablet before the exam and solve problems, which clearly does not give them pleasure.

This is easy to explain: if a person likes to do something, then the body adapts to it much more quickly, allocates additional energy to accomplish such a thing.

What are the symptoms of fatigue?

This can include the presence of "flies" and other foreign entities before your eyes, the need to squint to look at the screen.

There may also be a temporary veil before the eyes, increased tearing due to blinking, redness and pain( especially in the morning), itching. Sometimes it can double before the eyes.

Prevention

Some recommendations should be observed so that your eyes do not get tired or get tired as little as possible. This can include both the performance of all gymnastics, and the use of pharmacy medicines.

Water

Water has good relaxing properties and maintains muscle tone.

Take a small bowl, draw warm water into it, sprinkle it a little, dip your fingers and massage them with external eye muscles, especially those that are on the bridge of the nose and eyebrows.

And if you start to feel the first symptoms of fatigue, then wash your face with cold running water.

Gymnastics

Standard gymnastics for eyes, similar to that used for other diseases associated with visual acuity:

• Follow the movement of the index finger, and the finger lead towards yourself - from yourself, to the right - to the left.
• Look out the window, try to make out the outlines of distant objects, for example, flying birds, passing people, gaps between bricks or blocks at opposite houses on the street, etc.
• Describe the movement of the look of various shapes and patterns. You can write out the words by moving your nose on the table or a piece of paper. Children will especially like this exercise.
• Try to squint, while pulling the skin of the eyelids with your fingers. Such an exercise will give tone to the eye muscles.

In order to reduce the burden on the eyes, you need to be properly located in front of the computer. This is clearly shown in the following picture:

Physical activity

Physical activity normalizes blood circulation, nourishes the brain with oxygen and relaxes the entire body. Before you start working on the PC, do the charging before easy fatigue and "first sweat".

If you need to work long, then allocate 15-20 minute breaks in order to walk around the room, do gymnastics for the eyes, or for a walk down the street, if possible.

Monitor setting and special glasses

Set up the monitor by setting the refresh rate to 75 hertz( control panel - monitor settings), position it at least 70 centimeters from your eyes, which corresponds to the arm's length.

You can buy special glasses, this is not a panacea, but due to a change in the color spectrum of the light emitted by the screen, they do not allow the eyes to overexert.

Lighting

The main light should be behind your back or side, you should sit to the left of the window. The table lamp should not shine because of the monitor.

Monitor backlight and external light should be balanced: the screen should not be illuminated before the appearance of glare, but it should not be too bright in comparison with the light of a ceiling lamp.

Medications

The key to good performance is the full receipt of micronutrients into the body. Vitamins A and B are especially useful, and if they are deficient, vision can deteriorate without negative external factors.

It is useful to eat blueberries, if you can not buy berries yourself, you can buy her extracts, such as Blueberry Forte, in the pharmacy.

An artificial tear works well against the withered eyes - a synthetic liquid that has a composition similar to a natural tear.

Bury it every 3-4 hours of work for a PC, especially if you start to feel dry and burning in your eyes.

Results of

Working with a computer can cause fatigue and sagging of the eyes, which is associated with a number of physiological features( rare blinking, concentration of sight on one object), and psychological factors( routine and monotony of many types of work for PCs).

In healthy people this does not cause any pathologies and the eyes recover themselves, but this does not mean that you need to be indifferent to their condition.

It's much better to save them, doing gymnastics, keeping an eye on your head blood circulation and using medical support if necessary.

It is also important to observe a full-fledged diet for the body to get all the necessary substances.
