How to protect your eyesight when working at a computer | Article on computer science and ICT on the topic:

Shifting your gaze to distant objects

Position your computer in such a way that there is a far point behind the monitor that you can constantly look at. To avoid visual fatigue, give your eyes a rest. You can’t sit facing the windows, the wall, in the corners, all this negatively affects your vision, it’s better to turn your face in front of the door, so you can train your vision.

If your workplace is in a corner, you need to install a mirror on the table, so your eyes can look into it and rest, try to focus your gaze on those objects that are located behind.

Why does a computer, or rather radiation from a monitor, harm our eyes?

Reason #1

Radiation of harmful blue high-energy spectrum

The human eye is not designed to look at emitted light. This is how our eye works. The sun emits light in nature and you know what happens if you look at the sun for a long time.

Everything else we see around us is reflected light. Road, trees, water. The light first falls on all this, and then is reflected, falling into our eyes. But nature did not provide monitors and LEDs.

What you need to avoid is blue spectrum radiation. Almost any emitted light contains it, and monitors first of all.

Reason #2

Gaze stuck at one point

Our eyes get tired if they focus on one surface for a long time. That is why our parents told us that reading for a long time is harmful. We were forbidden to watch TV for a long time. And we, in turn, prohibit children from playing computer games for a long time.

Looking at one point creates visual fatigue, which people working at a computer feel everywhere.

Various eye exercises help relieve visual fatigue. But we don’t have time to do them, and we just don’t want to.

Solution: If the latest technologies harm our eyes, let them save us!

Avoid glare

Glare appears when reflections from light appear; they can be reflected by the monitor, which causes pain in the eyes. Glare also appears due to bright light bulbs, the sun from windows, and light that reflects bright objects.

If a person begins to be bothered by glare, the eyes quickly get tired, it is impossible to fully work with the computer, so the vision is overstrained, and pain occurs in the neck, back of the head, arms, and shoulders.

To find out if there are glares, you need to turn off the laptop, turn on the light, if you notice a reflection or glare on the screen, this indicates the presence of glare, to get rid of them, you need to turn the computer in the other direction, tighten the windows, close the blinds, turn off the lights, All light bulbs must be covered with a lampshade.

Causes of visual impairment [1]

Tired eye syndrome (asthenopia) is a diagnosis that appeared long before the advent of computers and was associated with long-term daily reading. Now that you mostly have to read not from paper, but from electronic media, eye strain increases due to backlighting, flickering of monitors, incorrect color rendition, changes in brightness, and glare. Asthenopia manifests itself in the form of several symptoms:

Weakening of the eye muscles. The visual apparatus is initially designed in such a way as to focus mostly on distant objects and track what is happening around. A modern person spends hours looking at a computer, TV or smartphone screen, so the eye muscles do not receive the proper load.
Eye fatigue. It is impossible to endlessly look at illuminated texts and pictures: eventually the eyes stop focusing and the image begins to blur.
Stinging and burning in the eyes . The frequency of blinking when working at the monitor is reduced, so the eyeball is not sufficiently wetted, which leads to pain. The eyes may begin to water and become red.

In addition to asthenopia, one should be aware of the harmful effects of light on the retina (photodamage), which accumulates over the years and leads to serious ophthalmological diseases.

Protecting your eyesight with protective screens

Offices often don't care about the placement of computers, so privacy screens can help. With their help you can limit the rays from hitting the screen. The protective screen improves the quality of images, making them high-quality, the eyes are better oriented in them.

Please note that low-quality screens are dangerous for eye health; they have poor resolution and frequency, which causes eyes to strain and get tired. It is recommended to carefully adjust the screen brightness; it should not be too high.

Anti-glare glasses for computer

Researchers were able to find out that modern people look at a screen at least 10 hours a day. Constant attention to a computer monitor, smartphone, tablet or TV causes the eyes to be in constant tension, which is expressed in the evenings by a feeling of slight discomfort, and for some it manifests itself as fogginess. This phenomenon is called computer syndrome. To protect your eyes from harmful effects, experts recommend using anti-reflective lenses.

Monitor the room lighting

If you no longer have glare, but your workplace is dark, you need to take urgent action; this also negatively affects your vision.

You cannot place a lamp between the laptop screen and yourself, as this will not only damage your eyesight, but also cause mental problems. All documents must be illuminated for work; for this you need to use a table lamp, the light should not fall on the screen area.

An indirect light from above is ideal, which can be constantly controlled; it should have up to three operating modes, so you can choose the optimal one for yourself.

Often in offices the room is too lit, in this situation you need to purchase darkening glasses. If yellow colors are constantly present on the screen, you need to choose blue or gray glasses. If you are constantly bothered by green colors on the screen, you should prefer green glasses. This way you can protect yourself from ultraviolet radiation.

How to relieve eye inflammation?

Seeing burst eye vessels in the mirror, many immediately grab the advertised vasoconstrictor eye drops. And they make a mistake. These eye drops should be used only on the recommendation of a doctor or as an “ambulance”.

Firstly, the use of vasoconstrictor drops will not relieve you of the disease that may be associated with redness of the eyes. And, of course, they will not relieve eye fatigue either. They will just narrow the blood vessels - and excessively. At the same time, intraocular pressure will increase - the organ of vision will not receive the required amount of oxygen. The result is even greater redness after the drug stops working. Regularly using vasoconstrictors will not relieve eye fatigue, but you also risk getting new troubles that even sitting at a computer around the clock will not provide you with!

The most common advice from doctors is to reduce the time spent “sitting” at the monitor; for computer workers, this is almost impossible. Therefore, it remains to “maintain” good eye condition, compensating for the damage caused by work if possible. In other words, it is necessary to methodically restore losses, by all means strengthening the ability of the visual apparatus to independently resist the harmful effects of the computer.

In this regard, many “benefits” for the eyes have been invented that can slow down the development of unpleasant symptoms. Among them: moisturizing drops, blackberry-based multivitamins, special exercises, safety glasses and a properly equipped workplace.

To relieve fatigue and inflammation of the eyes , use the means at hand: apply pieces of ice or a towel soaked in cold water to the skin under the eyes; moisten your eyelids with fresh cucumber juice; apply a compress of chamomile or regular tea to your eyes; alternately apply hot and cold cotton swabs soaked in sage infusion (1 tsp per half cup of boiling water); just get a good night's sleep!

Using an eye massager can be a good help in the fight for your eyes. This is an effective way to quickly relieve vascular spasm, relax the eye muscles, and improve blood supply to the eyeball.

Most massagers are small devices that resemble a mask or glasses. The most common devices are those that set in motion small probes that begin to pleasantly “stomp” near the eyes, providing a relaxing effect, similar to a regular mechanical massage. The effect can be enhanced by connecting a weak magnetic field to the probe plates.

Blinking to relieve tension in the eye area

This exercise is necessary so that the eyes can be constantly moisturized and cleansed, so that vision will be clear, the facial muscles can be relaxed, you will not wrinkle your forehead, and relieve tension.

Some people can constantly strain their eyesight because they open their eyes wide and do not blink them, because of this the eyes become significantly red, itching and severe burning may occur, this is especially true for those who use contact lenses.

You need to be able to blink correctly. Only the eyelid area should move, the forehead should remain motionless. You need to close your eyes carefully, without straining. The forehead should be completely relaxed. Blink as often as possible.

Are computer glasses good or bad?

Eyeglass lenses for protection from computers and gadgets most often look slightly yellowish. This is because yellow colors block the blue spectrum.

Using glasses for computer work

With the help of special safety glasses, you can protect your eyes from further problems with vision, it will not fall, vision will remain in good condition for a long time, if a person has never had problems with it. Anyone who suffers from myopia must wear glasses so as not to worsen their health.

In addition to using glasses, you must periodically perform all eye exercises. Please note that it is not recommended to work with bifocal glasses at a computer; they may cause neck problems and constant mental and physical fatigue. It is best to pay attention to special lenses and glasses for computers.

Thus, very often a person has to spend a long time at the computer, which causes problems with vision and eyes. For some, in addition to a sharp decline in vision, conjunctivitis and an inflammatory process in the eye area simultaneously develop - all this can lead to serious illnesses. Also, due to the fact that the eyes are strained, problems with the vascular system and neck may appear. Therefore, it is important to take care of the lighting in the room, perform special eye exercises, pay attention to the computer screen settings, and you may need to purchase special eye protection glasses.

Morning exercises for the eyes

In the morning, not only the muscles of the body need a little warm-up, but also the eyes. Therefore, it will not be amiss to learn how to systematically perform the following exercises. In total, morning exercises should take 10-15 minutes of time. It should take place calmly, without tension. Therefore, if you do it before getting ready for work, it is better to set the alarm early so as not to do it in a hurry.

Deep, even breathing for all exercises. This is very important, since only the correct supply and distribution of oxygen can contribute to the further normal functioning of the body. So, breathing evenly, you need to stretch a couple of times and roll over from side to side.
Simultaneous opening of the mouth and eyes, and this should be done as widely as possible and several times.
Close your eyes as tightly as possible. Then open your eyes and repeat the exercise 6 times.
Blink. Light quick movements 12 times.
“Draw” several letters or numbers with your nose. The exercise must be repeated 3-4 times. This will relieve tension in the cervical vertebrae.
Palming. Exercise described above. Enough 2-3 times for 1 minute.
Turns with your fingers (you can randomly rotate your fingers in different directions), while counting to 10.
