Computer Vision Syndrome: Causes, Symptoms, and Treatment

What Is Computer Vision Syndrome?

Computer vision syndrome, also referred to as digital eye strain, is a term used to describe all eye or vision problems that occur as a result of extended use of the computer use.

According to researchers, about 50%-90% of people who work at a computer screen display at least a few symptoms.

Computer vision syndrome doesn’t only affect the adults, children who stare at tabs or computers for too long can also develop this sight problem.

According to statistics, computer vision syndrome affects about 60 million people globally (1). If we continue straining our eyes without taking the basic precautions, it may inevitably lead to further eye complications.

How Do Computers Affect Vision?

Computer vision syndrome (CVS) is caused by the repetitive movement of your eyes in the same path for long durations.

When you are constantly looking at the computer, your eyes have to constantly focus and refocus. They keep moving back and forth from the computer to other things you may have to read or write down in between. They also react to the changing images on the computer screens.

Causes Computer Vision Syndrome

Some common causes of computer vision syndrome are:

  • Using computer under poor lighting
  • Not using your reading or anti-glare glasses regularly
  • Advancing age
  • Uncorrected ocular (vision) etiologies
  • Glare on your digital screens
  • Improper posture or viewing distances

Diagnosing Computer Vision Syndrome

An eye exam can be carried out by an ophthalmologist to diagnose your condition. Special attention might be given to how your eyes work and respond to different distances from the computer screen.

Your doctor may also question you about your symptoms and how much time you spend in front of the computer screen to confirm the diagnosis.

How To Treat Computer Vision Syndrome

It is essential to visit your ophthalmologist regularly for check-ups after computer vision syndrome diagnosis. This is to prevent your eyesight from getting worse.

Medical prescriptions may include glasses or contact lenses. You may be given a regular pair of glasses to wear while looking at the screen, or you may be asked to get a special pair. Single, bifocal lenses, or tinted lenses may also be prescribed to enhance contrast.

Some simple changes to your working area that can help with CVS are:

  • Fix a dimmer switch on the overhead fixtures that could be casting a glare on your screen.
  • You can also reposition your computer if the light from a nearby window is casting a glare on your computer screen.
  • Rearrange your desk slightly below your eye level and 20-28 inches away from your face.
  • Give your eyes a break by looking at least 20 feet away every 20 minutes for 20 seconds. This is called the 20-20-20 rule.
  • Adjust the font size and brightness of your computer so that you don’t have to strain your eyes.

Prevention Tips

While you don’t have to cut down on your screen time completely to prevent computer vision syndrome from resurfacing, a few changes to how you use them can make things easier on your eyes.

  • Use an anti-glare screen filter on your computer, phone, as well as tablet screens.
  • Take a break, for, say, about 15 minutes, after every 2 hours of continuously using the computer.
  • You can use artificial tears to lubricate your eyes if they appear to always feel dry.
  • Place a humidifier in the room, close to the screens, to prevent your eyes from drying.
  • Eat diet that is rich in vitamins and minerals.
  • Practice eye exercises like blinking slowly, rotating your eyes in the clockwise direction.
  • Ensure the lighting of your surroundings is bright enough for your screens.
  • If you are a contact lens user, wear your glasses and give your lens a break while using the computer screen.
  • Get your eyes checked by an eye care specialist regularly.
