Introduction

Computer-related vision syndrome is one of the terms that you often see and read on the Internet and in articles these days. The term is used to describe all ocular problems that result from long-term use of computers and tools such as computers, and sometimes the term digital eye pressure is used instead.

 

What is Computer Vision Syndrome or Digital pressure?

One of the most common problems of people who regularly stare to the computer screen of their mobile phones, tablets and laptops is the so-called computer- vision syndrome, which working with this tool for a long time causes eye fatigue and dry eyes.

The sum of the above problems is called cvs for short.

Statistics show that 50 to 90% of people who work with computers and similar tools have at least one sign of the symptoms of this complication and syndrome.

Do not think that it is only adults who get this syndrome. Children who play with tablets and computers for a long time can get the syndrome, especially if the position of their head and neck and the angle of their eyes to their computer is not standard or they have used this tool non-standard.

 

How is computer vision syndrome created?

This syndrome is the result of your eyes being exposed to digital screens. Computer vision syndrome affects about 60 million people worldwide. If you continue to work without considering the standard and precautionary measures, you may have more physical and mental problems and even more eye problems.

So why staring at a computer and digital screens causes computer vision syndrome?

When you stare at digital screens, there are major differences compared to when you stare at a book. According to studies conducted by reputable universities, when a person works with a digital screen computer, he blinks less, so as the number of blinks decreases, the amount of tears spread on the eyes decreases.

It is said that the number of blinks in people who stare at the computer for a long time is reduced by one third, the eyes become dry and the person will be prone to many problems.

Another reason is that when a person looks at a digital screen, the light emitted will be more than books when displaying the letters on these screened pages, and the letters will be displayed to the user in a completely different way.

The set of factors described, increases the activity of the eye to see and understand what is visible on the screen of a digital screen the person suffers from eye fatigue more often, when the person stares at digital screens at a distance less than the standard angle, this feature will aggravate eye discomfort.

 

What are the clinical signs and symptoms of a person with computer vision syndrome?

First of all, credible studies have not yet provided evidence that computer use can cause permanent long-term damage to the eyes, but prolonged use of digital screens can increase fatigue and pressure on the eyes. The clinical manifestations of people with computer vision syndrome are as follows:

  • Neck pain and headache
  • Low back pain
  • Inflammation of the eye
  • Eye irritation
  • Dry eyes
  • redness of the eye
  • Blurred vision
  • diplopia

 

what is the reason?

Computer vision syndrome will develop when users' eyes and brains have problems. At this time, the user's eyes and brain behave differently from the text and image displayed on the digital screen than when they want to see the print on paper. The writings on the digital pages do not have the clarity of the writings of the books, and the glare and reflections received from the digital page create problems in the individual's vision.

we have to say that words, images, and digital screens are made up of very small light dots called pixels that have a higher brightness in the center. and the more we go to the margins the intensity of their color decreases, So it is difficult to focus the eyes on the letters of the computer.

So, at this time, your eyes are more inclined to return to the level of reduced concentration. In this case, the eyes involuntarily go to rest and then return to the focus state with pressure. This change in state causes a lot of fatigue in the eye muscles and a lot of pressure and work. It is obvious that people feel it when working with a computer for a long time.

 

What causes the above syndrome, which is also called digital eye pressure syndrome?

Why do people get computer vision syndrome?

You may ask, what are the causes of this syndrome, also called digital eye pressure syndrome?

Some of the common causes are as follows:

Aging, weak light, refractive errors in the user's eye, not using glasses regularly, not using anti-reflex glasses regularly, high screen light, being in an inappropriate position and non-standard distance from the monitor. if your doctor gave you contact lenses, do not forget to use them to work with digital screens, do not forget this point! You may also be prescribed Bifocal contact lenses with transparent color power embedded inside the material.

You can follow the tips below to be safe from computer vision syndrome, and if you have this syndrome, following the tips will help alleviate your discomfort:

The light that shines on the monitor screen at work should be redirected. If the light from the window close to the monitor is an annoying light, you should change the position of the monitor so that the light does not shine directly on the screen.

The second thing to keep in mind is to reduce the light on the monitor as much as possible. The third point is that the desk on which your work tool and computer or laptop are placed, should be adjusted so that it is slightly lower than the direction of your eyes and has the necessary distance from the eyes. The next point is to get up every 20 minutes and look at something that is 20 steps away from you for 20 seconds. This rule is called the 20-20 rule.

Change the fonts size so that you can easily see them without putting pressure on the eyes.

Here are some tips to help keep your eyes healthy when sitting at a computer:

Learn to sit properly behind a desk. Your back should be straight. Your shoulders should go back. The top of the monitor screen should be in line with your eyes. When you type, your body should be balanced and fit. The wrist should be slightly lower than the elbow.

This position will help you avoid carpal tunnel syndrome, which causes pain in the wrist. Keep your legs bent at the knees so that your knees are slightly higher than your hips.

Keep the soles of your feet flat on the floor or on a stool with a suitable footrest. It is best to get up every 20 minutes to half an hour, do stretching exercises or walk for a few minutes.

Your legs should be stretched and you should avoid looking at the monitor screen for a few moments.

Do not sit still for a long time to prevent blood clots in your legs, Blood clots in the legs are very common in middle-aged users.

To flex your neck, move your head back and forth left and right, Never rotate your head around your neck and move too fast as it will seriously damage your cervical spine.

If your job is to type for a long time, after a while you must rotate your hand in a circle and exercise.

When sitting, bring your feet to the toes and put them back on the floor. Do this until your feet are tired. Do this continuously for an hour. This movement strengthens your legs. Take a deep breath every few moments. Make sure the open air is flowing in your workplace. Pull the back of the chair back and give it an angle of more than 90 degrees.

The environment in which you work with the digital screen should not be too bright and should not be dark because both conditions will put pressure on your eyes. Redness, burning, watery eyes, blurred vision, eyeball pain, fatigue and headache are common eye complications when working with digital screens.

The bottom line is that people with uncorrected refractive errors, such as binoculars, presbyopia, and astigmatism, are more likely to have eye fatigue because they narrow their eyes more, Thus, people with refractive eyes have a higher risk of developing digital or computer vision syndrome.
