Expert Opinion
Many people ask if it's possible to go blind from a computer. It is known that the monitor provokes eye fatigue, causes excessive eye strain. Often, after long-term work at the computer, a person even starts to have a headache. Therefore, this affects the state of the body negatively.
But experts say that if you are at a PC even 14 hours a day, a person cannot go blind.
Hygiene rules
So is it possible to go blind from a computer? The active use of the PC is fraught with exorbitant eye strain (as we discussed above) and even a decrease in visual acuity. Get away completely fromdamage is unfortunately not possible. At the current level of technological evolution, there is no maximum protection against the influence of the monitor.
And yet the damage to the computer can be minimized. It is enough to follow the rules of hygiene of the visual organs. If a person stays at the monitor for too long, his eyes will get tired. But even those who are at the PC every day until 2 pm do not lose their eyesight. This is dictated by the ability to provide reasonable eye protection.
You should take your eyes off the PC monitor every 20 minutes. It is enough to look out the window or into the distance for only 20 seconds. It is also necessary to remember that eye fatigue is increased by glare on the monitor. To prevent visual impairment, place the monitor below eye level. This will prevent pain in the neck.
The perfect 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 you feel comfortable while working at your computer.
Other recommendations
Now you know the answer to the question, is it possible to go blind from the computer if you sit at it a lot. By the way, do not forget about a good rest from work behind the monitor. Also, experts strongly advise visiting an eye doctor at least once a year. This will help you keep track of your visual function.
Details
So, now you know that going blind from a PC is, perhaps, unlikely. But the visual organsadapt to the computer, so there is a risk of developing myopia. After all, if a person stays in confined spaces for too long, the eye adapts to short distances.
Myopia is more likely to develop in those who work at a PC than in 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. Mostly children.
Why do many people blame the PC for the deterioration of vision?
Working for a PC, a person is in tension, which is not related to the responsibility for the work that he performs. The reason is that the PC is placed too close. From a biological point of view, everything that is nearby is a greater danger than what is far away.
That's why it's not so much about the PC itself, but about the tension experienced from tracking nearby objects. Because of this, we blink less often, our eyes dry out, especially in conditions of unnatural heating. Irritation occurs, the eyeball becomes red. If you read texts from a sheet of paper, the consequences will be identical.
How to protect your eyes?
In the room where you work, during the heating season, you can place humidifiers. If your eyes are dry, you can also use tear replacement drops, which your eye doctor will prescribe for you.
Infrequent blinking, dry air, short distance work lead to discomfort. Do you think that ina foreign body has got into your eyes, you feel a burning sensation - these are all symptoms of a visual computer syndrome. And if a person daily works at a PC in a room with dry air, the symptoms will worsen.
PC glasses
Glasses for PC work are a kind of barrier that creates a special microclimate around the eye. In this area, they probably work. 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 out as blinking slows down.
Safe rate
An adult can work at the monitor as long as he needs. But you should also take breaks at least every 40 minutes: relax, rest, blink well, look into the distance, put moisturizing drops in your 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 dryness due to infrequent blinking and the visual organs are inflamed.
If you wear contact lenses while working at 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, take vitamins as recommended by the doctor.
The impact of monitors on children's vision
Can you go blind from a computer after 10 years? We are offering to youread a short list of tips on how to reduce the harmful effects of tablet, PC and smartphone monitors on children's vision.
- If you try to hide all this equipment from the kids longer, there will be no trouble. Remember that all these technologies are not recommended for babies under two years of age.
- The older your baby is, the more time he can spend at the PC: from 3 to 5 years - 15 minutes. per day, 6-7 years old - 20-25 minutes, 8 years old - 40 minutes, 9-10 years old - no more than 1.5 hours (required with breaks).
Then your child will be much more difficult to control, as he will already be old enough. And today, 1.5 hours a day at a PC is too little, since almost all preparation for lessons is carried out using this machine.
It is better to teach your child to do exercises for the eyes and breaks every hour. Teach your child by example - it won't hurt you to work like that either. While 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 properly work with any computer devices. And here, not only is it important to keep the right distance, correct posture also plays a big role.
Smartphones
We continue to find out further whether it is possible to go blind from a computer and a phone. Smartphones (phones) are not toys. Even if they try to make them. Smartphones have very small screens, so they put a huge strain on the eyes.
If you are a childif you want to give a gift, it's better to buy him a tablet with a diagonal of 9, 7-10, 1 cm. Always get high-quality devices. Cheap things are good when they are disposable. But computer equipment should be of high quality, then the impact of the monitor on the baby's eyes can be minimized. This rule also applies to adults.

Always hold your smartphone at least 40 cm away from your face. The closer you place it to your eyes, the faster you will become myopic.
And if you already have myopia?
Some people wonder if it is possible to go blind from a computer with myopia. Experts recommend that people with myopia reduce working hours at the PC, take breaks more often, relax on vacation and on weekends.
Also, doctors advise doing exercises for the eyes (movement in directions, squinting, rotation, etc.) and general strengthening exercises. They say that under normal working conditions it is possible to stop the progression of myopia.
Doctors say that it is best in this case to work 3-4 hours in the morning and 3 hours in the afternoon with hourly breaks of 15 minutes. On weekends, you need to relax, as an exception, a couple of hours at a PC, no more. It is not recommended to work in the evening or at night. Take care of yourvision and stay he althy!
