Work and study force us to spend long hours in front of the computer. Its use can cause injuries that are not noticeable at first glance, but these are progressive and are the product of an abuse of time dedicated and little rest.
Although it is estimated that the radiation emitted by television is more significant than that imparted by a monitor, it is estimated that the principal risks of being in front of the computer for long periods are that there is discomfort in the eyes, such as visual fatigue, redness, vision blurred and even headaches. A scientific reason that proves what has been said is that the human eye is naturally designed to look at a distance, so focusing on a nearby screen for hours logically causes muscle fatigue.
Fortunately, most of them are mild ailments that, as we say, can be easily alleviated by adopting some simple guidelines, which we explain in detail below. You only have to incorporate them into your daily life to avoid that those long hours in front of the PC take a toll on your health.
Of course, we intend to replace the professional advice of a physician. If you have any of these symptoms and adopting the suggestion that we give you in this article does not improve, it is best to go to the appropriate specialist.
- Red eyes
The eyes are potentially the organ that damages most from continued screen use. Because it is no longer just a matter of working eight hours a day with the PC, but when you leave work you continue with your mobile, and then at home with the tablet or laptop, and night with the TV … too many screens at the end of the day.
Therefore, it is not unusual for all of us to end up with swollen or irritated eyes or an unpleasant sense of dryness. This occurs because when we look at a screen, we tend to blink less than necessary, so the eyes do not receive the required dose of hydration. It also influences the monitor’s position or whether there is heating or air conditioning in your workplace.
How to solve it
Fortunately, this problem usually disappears within a few hours of stopping using the screen. If not, you can use artificial tears to help relieve dryness. It is also essential to adjust your monitor’s brightness and contrast levels and ensure that you are not too close to the screen. Your eyes are potentially the organ that damages most from continued screen use main light source is not hitting your face or directly on the screen. You can also purchase a pair of computer glasses that are specifically designed to protect your eyes from the adverse effects of light emitted from your computer screens.
Also, check that the position of the monitor concerning your sight is correct: its upper part should be aligned with your eyes so that when looking at it, you slightly tilt your view and thus do not open your eyes too much (you will prevent them from drying out so much).
- Visual fatigue
The fact that the eyes are one of the most affected by work in front of the computer means that they can suffer from more than one condition. Thus, in addition to red eyes, excessive use of screens can cause eyestrain.
You will recognize it right away: it is not only that your eyes are red or itchy, but also that you feel tired; it is as if they hurt, like when your muscles ache after a good training session in the gym. Because after all, the eyes are also controlled by muscles, and these suffer if we abuse them.
And yes, the eye muscles are abused by spending so many hours in front of a mirror. If we look in the distance, the eyes are calm, but we demand more effort by continually concentrating on things near. And eye strain makes its debut after a few hours.
How to solve it
Again, this problem is relatively easy to alleviate. Some tips from the previous point can be applied here, too, such as those related to the screen’s brightness and contrast values or the room’s light source. But you can also apply others such as taking breaks from the screen frequently and take the opportunity to look into the distance, or even cover your eyes for a few minutes to give them a little rest and darkness.
A trick that works very well in these cases is the so-called “20-20-20 rule”: every 20 minutes, look for 20 seconds at an object 20 feet (about six meters) away. This will help relax your eyesight.
Remember that these are just a series of basic tips to prevent and alleviate the health problems normally associated with computers. If you have any of these symptoms and do not get them to go away, see your doctor header for help.
