Is it possible to go blind from a computer? How many hours a day can I spend on a monitor? You will find answers to these and other questions in the article. Today, many people use a computer daily. And for office workers, it has become an indispensable tool. Is it possible to go blind from the computer, find out below.
The opinion of experts
Many people ask if it is possible to go blind from a computer. It is known that the monitor provokes eye fatigue and causes excessive eyestrain. Often, after a long time working at a computer, a person even begins to have a headache. Therefore, this affects the state of the body negatively.
But experts argue that if you stay at the PC even 14 hours a day, a person cannot go blind.
Hygiene rules
So is it possible to go blind from a computer? Active use of a PC is fraught with exorbitant eye strain (as we discussed above) and even a decrease in visual acuity. Unfortunately, it is impossible to get away completely from such damage. At the current level of technology evolution, extremely reliable protection against the influence of the monitor is not provided.
Nevertheless, the harm of the computer can be minimized. It is enough to observe the rules of hygiene of the visual organs. If a person stays behind the monitor for too long, his eyes will get tired. But even those who are at the PC every day for up to 14 hours do not lose their vision. This is dictated by the ability to provide acceptable eye protection.
You should tear yourself away from the PC monitor every 20 minutes. Just look out the window or into the distance for only 20 seconds. It is also necessary to remember that eye fatigue is enhanced by glare on the monitor. To prevent vision loss, set the monitor below eye level. This will prevent the occurrence of pain in the neck.
An ideal distance from the visual organs to the PC screen is considered to be 50-70 cm. But, if this is not observed, you do not need to bend or stretch to achieve the required position. It is important that when working at the computer, you do not feel discomfort.
Other recommendations
Now you know the answer to the question of whether it is possible to go blind from a computer if you sit a lot at it. By the way, do not forget about a full rest from work behind the monitor. Experts also strongly advise visiting an eye doctor at least once a year. This will help track the state of visual function.
Details
So, now you know that blinding from a PC is probably unlikely. But the visual organs fit in with the computer, so there is a risk of myopia. After all, if a person has been in enclosed spaces for too long, his eyes adjust to short distances.
Myopia often develops for those who work for a PC than for those who repeatedly look into the distance and are constantly in open spaces. By the way, only 3-4% of the total population are biologically predisposed to the occurrence of myopia. These are mainly children.
Why do many blame PCs for impaired vision?
Working for a PC, a person is in tension, which is not connected with responsibility for the work that he performs. The reason is that the PC is too close. From a biological point of view, all that is nearby is a greater danger than what is far away.
That is why the point here is not so much in the PC itself, but in the tension experienced by tracking nearby objects. Because of this, we blink less often, our eyes dry out, especially in conditions of unnatural heating. There is irritation, the eyeball turns red. If you read texts from a paper sheet, the consequences will be identical.
How to protect your eyes?
You can place humidifiers in the room where you work during the heating season. If your eyes dry, you can also use tear drops - they will be prescribed by your eye doctor.
Rare blinks, dry air, work at a short distance lead to a feeling of discomfort. You think that a foreign body has come into your eyes, you feel a burning sensation - these are all symptoms of a visual computer syndrome. And if a person works daily for a PC in a room with dry air, the symptoms will worsen.
Glasses for working at PC
Glasses for working with a PC are a kind of barrier that creates a special microclimate around the eye. They probably work in this area. But it is unlikely that the color filters of glasses can somehow reduce the load on the organs of vision. Regardless of whether a person works with or without glasses, the surface of the eye dries up, as blinking slows down.
Safe rate
An adult can work on the monitor as much as he needs. But it is also worth taking breaks at least every 40 minutes: relax, rest, blink well, look into the distance, drip moisturizing drops into the eyes.
Contact lenses
Everyone knows that contact lenses are on the surface of the eye. That is why they can, like a foreign body, cause an inflammatory reaction. Add the dryness that comes from infrequent blinking - and the visual organs become inflamed.
If you wear contact lenses when working on a PC, visit your eye doctor every 6 months. If recommended, use special moisturizing drops.
By the way, to improve the stability of the retina, on the recommendation of a doctor, take vitamins.
The effect of monitors on children's vision
Is it possible to go blind from a computer after 10 years? We suggest that you familiarize yourself with a short list of tips on how to reduce the harmful effects of tablet monitors, PCs and smartphones on children's vision.
- If you try to hide all this technique longer from the kids, there will be no trouble. Remember that for children under two years old, all these technologies are not recommended.
- The older your baby, the more time he can spend on a PC: from 3 to 5 years - 15 minutes. per day, 6-7 years - 20-25 minutes, 8 years - 40 minutes, 9-10 years - no more than 1.5 hours (required intermittently).
Further, your child will be much more difficult to control, as he will already become quite old. And today, 1.5 hours a day for a PC - this is too little, since almost all preparation for lessons is carried out using this machine.
It is better to train your child to do gymnastics for the eyes and breaks every hour. Teach your child by personal example - it won't hurt you to work like that either. As long as there is vision, it must be protected, and not saved, when it is already planted hopelessly.
Distance is the law. Teach kids from an early age to work properly with any computer device. And here it’s not only important to keep the right distance, correct posture also plays a big role.
Smartphones
We continue to find out if it is possible to go blind from a computer and phone. Smartphones (phones) are not a toy. At least they are trying to make them. Smartphones have very small screens, so they give a huge load to vision.
If you child want to make a gift, it’s better to buy him a tablet with a diagonal of 9.7-10.1 cm. Always purchase high-quality devices. Cheap things are good then when they are disposable. But computer equipment should be high-quality, then the impact of the monitor on the baby's eyes can be minimized. This rule also applies to adults.
By the way, forget about using a smartphone in a dark room. After all, bright backlighting, coupled with a lack of lighting, greatly harm the eyes. Use the telephone only in daylight or in a well-lit room.
Always keep your smartphone at least 40 cm from your face. The closer you put it to your eyes, the faster you will have myopia.
And if myopia is already there?
Some people wonder if it is possible to go blind from a computer with myopia. Experts recommend that people with myopia reduce working hours for PCs, take breaks more often, and relax on vacation and on weekends.
Doctors also advise performing exercises for the eyes (movement in directions, squinting, rotation, etc.) and general strengthening exercises. They say that under normal working conditions, the progression of myopia can be stopped.
Doctors say that in this case it is best to work 3-4 hours in the morning and 3 hours after dinner with hourly intervals of 15 minutes. On weekends, you need to rest, as an exception, a couple of hours at the PC, no more. Evening-night work is not recommended. Take care of your eyesight and be healthy!
