What Is Digital Eye Strain? + What to Do About It

In today’s digitalised world, problems with digital eye strain have started to show signs of sharp increase.

Today we give you a good summary of what you need to know about this modern world problem and most important, what to do about it.

What Is Digital Eye Strain?



Digital eye strain is also referred to as computer vision syndrome and is a set of vision related problems that result from extensive use of a computer, smart phone, or tablet.

The majority of people that use a computer will at some point experience digital eye strain.

What Causes Digital Eye Strain?


Basically, blue light emitted from digital devices and the fact that this light flickers are the major causes of digital eye strain.

1. Blue Light



Whilst there may be many factors that leads to digital eye strain blue light seems to be the biggest culprit.

Blue light is high energy visible (HEV) light that is emitted in large quantities from digital devices, such as your smartphone, laptop and tablet.

Given how high energy artificial blue light is; it may also cause some cellular damage in the eyes. After a long day working on your computer (which emits lots of blue light), the cumulative damage caused by this excessive blue light exposure can lead to digital eye strain.

2. Reduced Contrast

Blue light from digital screens can decrease contrast, which is the main cause of digital eye strain.

Fatigue caused by excessive blue light exposure after sunset disrupting your circadian rhythm and sleep can also lead to digital eye strain.

Dim lighting, which is still blue light can also intensify the symptoms of digital eye strain.

3. Flicker Effect



Digital displays have a flicker rate that is also a major cause of digital eye strain.

Almost all LEDs flicker. This flickering blue light can be found in computer screens, cellphones, tablets but also in office and house lighting.

Flickering light is due to the AC current and is an energy saving tactic. This is all very well but this flickering effect of blue light also leads to digital eye strain.

What Are the Symptoms of Digital Eye Strain?

These are the symptoms one can experience from digital eye strain:

  1. Sore eyes
  2. Tired eyes
  3. Burning eyes
  4. Red or itching eyes
  5. Dry or watery eyes
  6. Blurred or double vision
  7. Tension type headache or migraine
  8. Uncomfortable neck, shoulders or back
  9. Sensitivity to light
  10. Trouble concentrating on computer tasks

Symptoms of digital eye strain seem to increase with the amount of time spent at a computer. Therefore, the longer one spends at a computer or on their phone the more severe the symptoms of digital eye strain.

Digital eye strain does not discriminate and anyone who uses a computer or works under blue light will experience digital eye strain at some point in their lives.
