In the age of high technology, it would never occur to anyone to give up computers and smartphones. However, many users fear that such a technique is harmful to health. We figured out whether the use of computer devices causes damage to the eyes and how to counter this.
Taking Care From a Young Age is Important
Even the most modern computer developments do not provide complete protection against harmful effects. According to statistics, about 70% of users in the world suffer from computer vision syndrome, which was identified in the 90s.
When working at a computer for a long time, the eyes do not have the necessary phases of relaxation, the accommodative muscles are constantly in tension. The doctor notes that this leads to a decrease in efficiency, as well as blurred vision, difficulty in focusing when shifting gaze from near to distant objects, and redness of the eyes. There is also a dry eye syndrome, which is accompanied by burning, tearing, and the sensation of a foreign body. In addition, users may experience double vision and pain when moving their eyes.
If in adults such phenomena disappear sooner or later, then in children prolonged work in front of the monitor can cause irreversible consequences, since the formation of the organ of vision is still ongoing. The consequence may be the progression of myopia (nearsightedness) and headaches.
Adults can work at the computer for an hour, after which the eyes need rest. It is also recommended to set aside a day when a complete rejection of computers is possible. It would be advisable to refrain from playing National Casino Canada games, watching movies, and simply having a good time with your friends and family.
Experts advise all users to do eye exercises during breaks, which helps to relieve eye strain and improve local blood supply. And every two hours, exercises are recommended to relax the muscles of the neck.
When dry eye syndrome is identified and confirmed, it is necessary to use tear substitutes to better moisturize the surface of the eye. To reduce eye strain, experts recommend holding the monitor at arm’s length (at least 50 centimeters).
Go For a Walk
You should not limit yourself and your children to using computer technologies, but it is important to make communication with technology correct and safe. Experts note that the problem of visual impairment is primarily associated with a change in the lifestyle of modern people. So, in the era of computers and gadgets, both adults and children rarely go for walks, preferring to spend time in front of monitors.
It has been proven that the lack of daylight provokes the development of myopia. Natural light has a positive effect on the proper growth of the eyeball, preventing its rapid jumps.
Distance is Important
The computer should be at a distance of 50-70 centimeters from the eyes, and the tablet and phone can be placed at least 30 centimeters from the organ of vision. A distance of 30 centimeters must be adhered to when performing any work that requires keeping something at a small distance from the eyes.
Adhere to the 20-20-20 rest rule, which means that you need to take a break after every 20 minutes for 20 seconds and look at distant objects at a distance of 20 feet (6 meters).
If an adult or a child intends to watch any videos on the Internet, then this should be done on a computer, since it is possible to place it away from the eyes. It is better to watch cartoons and films not on a tablet or phone, but on TV at a distance of 2–3 meters. Its diagonal should be 40–50 inches.
