EYE ISSUES

How to prevent Computer Vision Syndrome

Let’s be honest, we spend most of our days in front of our screens: working from computers, relaxing in front of the TV and by staying constantly connected to the world around us through our smartphones. 


We are the digital generation and we love the possibilities that come with it. However, there’s a price to pay: focusing continuously on our variety of screens can make us suffer from Computer Vision Syndrome. Are you familiar with this syndrome?


Let’s delve into what causes Computer Vision Syndrome and most importantly, how to prevent Digital Eye Strain!

What is Computer Vision Syndrome?

Computer Vision Syndrome (CVS) refers to eye problems and vision discomfort that may appear after spending many hours in front of our computers, tablets, TVs and phones, which creates stress on our near vision. 

It is also known as Digital Eye Strain – named after one of its most common symptoms.

We have all probably experienced it at some point: the feeling that we need to close our eyes for a minute or two to give them a rest. 

Typically, depending on the amount of time spent in front of screens, the level of eye discomfort and symptoms of CVS may vary, but it is more common than we might think. 


What causes Computer Vision Syndrome?

Two of the main reasons why screens make our eyes focus harder are:

  • Blue light overexposure
  • The glare they emit

This kind of light, also referred to as HEV, has the shortest wavelengths and the strongest energy, which results in the continual flashing and also the glare that our digital screens produce.

When we are looking at a screen, our eye muscles are fully activated! They are adjusting constantly!  


They quickly absorb information from the four corners of our screens, adjusting rapidly to the different lights and the constant motion of our scrolling. As a result, the longer we are behind a screen, the harder our eyes have to work, and you guessed it, right? After such a prolonged effort, our eyes become exhausted.

Symptoms of Computer Vision Syndrome

According to the American Optometric Association (AOA)[1], the most common symptoms of Computer Vision Syndrome are the following: 

  • Eye Strain: eye fatigue and discomfort
  • Dry Eyes and itchy eyes
  • Redness of eyes and a burning sensation
  • Blurred Vision or Double Vision
  • Headaches
  • Neck and Shoulder pain
