The sense of sight is indeed a blessing. But, we tend to neglect this gift and subject our eyes to a lot of stress and strain every day. We end up working every day for a good 8-9 hours in front of computer/laptop screens, only to return home and start playing games on our cell phones. And then, there are the social media updates that have become part and parcel of most of our lives.

Computer vision syndrome is a result of all such digital exposure that we put our eyes through. Globally, computer vision syndrome affects about 60 million people. If we continue straining our eyes without taking the basic precautions, it may inevitably lead to further eye complications.

What Is Computer Vision Syndrome?

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

Researchers are of the opinion that around 50%-90% of individuals who work at a computer screen exhibit at least a few symptoms.

However, it is not only the working adults who are affected. Children who stare at tabs or computers for too long can also develop issues, especially if the lighting and their posture are far from ideal.

You might be wondering how computers can affect your vision. Find out in the next section.

How Do Computers Affect Vision?

Computer vision syndrome (CVS) is kind of similar to carpal tunnel syndrome as well as other motion (repetitive) injuries you are likely to get at work. It 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 focus and refocus constantly – time and again. 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.

While such jobs may look easy, they require a lot of effort from your eye muscles.

Let’s now take a look at the causes.

What Causes Computer Vision Syndrome Or Digital Eye Strain?

Some common causes of computer vision syndrome are:

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

Those suffering from this syndrome exhibit the signs and symptoms listed below.

Signs And Symptoms

The common signs and symptoms associated with computer vision syndrome are:

  • Blurred or double vision
  • Eye fatigue
  • Floaters
  • A burning sensation in the eyes
  • Dry eyes
  • Eyes may become red and watery
  • Irritated eyes
  • Headaches

So, are there any tests that can help the doctor diagnose this condition?

How Is Computer Vision Syndrome Diagnosed?

The opthalmologist can help diagnose your condition by carrying out an eye examination. 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.

Once diagnosed, you may be asked to make a few simple changes to your working style. The following are some of the widely accepted practices for treating CVS.
