Causes of Computer Vision Syndrome and How to Prevent it

Computer vision syndrome (CVS), or often also referred to as visual fatigue and digital eye strain, is a term for a collection of symptoms related to eye disorders resulting from the use of electronic-based devices , such as laptops, desktops, mobile phones , and tablets .

Symptoms that usually accompany CVS are fatigue or aching in the eyes, blurred or double vision, and red, dry, or hot eyes. Even in some cases, headaches, necks, shoulders and back can be accompanied.

Causes of Computer Vision Syndrome and How to Prevent it

The longer the duration of computer use, the longer the symptoms will last, even continuing after computer use is complete.

How Does Computer Use Cause ?

Computer vision syndrome can occur due to several reasons, namely:

  • When looking at the screen, the eyes keep moving from one point to another and focus for a long time. This activity requires hard work from the eye muscles.
  • The letters on a computer screen are generally not as sharp as in the print media, so unconsciously it will force our eyes to focus more on reading them.
  • Flickering and glare coming from the screen adds to the workload on the eyes.
  • Frequency of the eye to blink tends to decrease when staring at the screen. This causes the eyes to become drier.

How To Prevent

About 50-90% of individuals who work using computers are reported to experience CVS symptoms. However, you do not worry. There are several ways you can do to prevent this condition, namely:

1. Adjust the ambient light

Make sure the light in your environment is not too bright or too dark, by:

  • Avoiding sitting facing or facing away from the window directly, because it will interfere with vision to the screen.
  • Closing the window blinds, if the sunlight feels too glare.
  • Adjusts the position of the screen, to reduce the reflection of light from windows or lights.
  • Adjusts the position of the table lamp's light so it doesn't point directly to the eye.

2. Arrange your work table

Adjust the location of the computer screen so that your gaze is directed toward the center of the screen at a distance of 50-70 cm from your face. If you work using a computer and books, use the book stand to place the books so they are parallel to the screen. The aim is to reduce the movement of looking down and looking up repeatedly.

3. Change the settings on your computer screen

Adjust the brightness, contrast, and font size according to your convenience. If necessary, use the screen filter to reduce the flashing lights from the screen.

4. Limit computer usage time

It is recommended that you limit the time for using gadgets, including computers. During computer use:

  • Blink your eyes often to moisturize your eyes while working.
  • Do the 20-20-20 tip, which is to look away from the screen every 20 minutes to stare at distant objects (about 20 feet or 6 meters) for 20 seconds. Twenty seconds is the time needed for the eye muscles to finally relax.

5. Use artificial tear drops

If necessary, you can shed artificial tears to help moisturize the eyes. Artificial tear drops can be purchased without a doctor's prescription, but make sure they do not contain the active ingredients of the drug or preservatives, so they do not cause side effects on the eyes.

6. Overcome other eye conditions that have

Use glasses with the appropriate lens if you have nearsightedness (myopia), farsightedness (hypermetropia), cylindrical eyes (astigmatism), or old eyes (presbyopia) to help the eye work.

The symptoms of computer vision are really harmless and are generally temporary. However, this condition can cause discomfort and obstacles in doing daily work. It's best to consult with an eye specialist if your symptoms continue or even get worse, even if you are not using a computer-based device.
