What happens to your eyes when you spend the day at your computer?


If it is not proven that the computer can alter our view of the long term, it is in any case certain that causes fatigue, irritation and pain in the eyes after heavy usage.

This is what is known as Computer Vision Syndrome. After a long day working on your computer, or hours spent surfing the internet and watching movies, you often do not have eyes in the face of the holes. Dry, tired and sometimes painful, your eyes are definitely experiencing the so-called computer vision syndrome, better known by its English name from Computer Vision Syndrome (CVS).

If it is not dangerous, this event is not less abnormal and can hurt your productivity. Too much screen reading dries out the eyes despite what you might think; this is not the computer screen itself that harms your eyes. “There is nothing inherently wrong with the computer, actually,” said optometrist Jeffrey Anshel the Vox site. “It’s the fact that we use it for just about everything.” On our computer, we read our emails, journals; we stroll on sites to search for information, photos or videos. In the end, much of our day is devoted to reading on screen.

But “reading requires attention and we forget to blink often,” says James Sheedy, professor of optometry at Pacific University. Several studies have shown that when we read on a screen, we do not quite blink our eyes, so they end up drying up. This phenomenon also occurs when we read printed text. But on the computer, the problem is exacerbated by our position. When we look at a screen right in front of us, our eyes are open, more than if we read a book, for example. A larger area of the eye is exposed, and it dries faster. Then you feel a sensation of dryness and irritation.


Headaches can also appear, and this is due to the effort that must provide us to focus on what we read or watch. Excessive brightness of the screen also causes eye strain. Doctors have also found that more and more young people are struggling to focus on distant objects after a long time spent in front of a screen. From 40 or 50 years, most people are affected by presbyopia, a condition that makes near vision increasingly difficult. Among young people, today is the opposite occurs, but an ad hoc basis. “I saw many people in their twenties and thirties who had trouble making the development. In general, when they looked away, they had a few extra seconds to make things become clear, “said James Sheedy.

This problem occurs after a long day of work, and not permanently. But computers can they also damage our vision for the long term? Can the computer alter the view? The answer is still unclear.

Specialists are not now able to link the massive use of screens with the increase in cases of myopia in the past 30 years. It is difficult to conduct studies on the subject, asking a group of people to move from screen to compare it to a group using the computer daily. However, some doctors believe that computers could be responsible for the new appearance of myopia scheme.

When we read a book, we usually direct our gaze downward. “When we look at a computer, it is right, more horizontal. And as shown by the studies, our ability to focus is not as good in the right position when we look down, “says optometrist. Forcing us to focus on small letters looking straight ahead we can accentuate the tension of the eyes, and eventually promote the development of myopia. Which is currently certain is that the computer work can put you back problems and neck pain in the long term, even when you are away from your screen. Good habits can fix these problems, and limit the impact of the computer on your eyes. Some tips to reduce eye fatigue and pain.


There are different methods to protect ourselves:

  • Start by setting your screen. Place it at least 50 centimeters of you, so you look slightly down.
  • Adjust the brightness and contrast.
  • Take regular breaks. Go out taking the air every two hours, even if you are not smoking!
  • Your screen should be at 90 ° to the windows (if any).
  • Look away from the screen eyes every 20 minutes for about twenty seconds at least.

It is on this last point that this post is dedicated. Eye Break reminder app offers a tool that is simple and practical. This is a timer that runs in a loop all day and plays an alert every 20 minutes. You’ll know it’s time to look away and relax the view.
