Computer Vision Syndrome [CVS]

How to prevent Computer Vision Syndrome

How to prevent Computer Vision Syndrome

Let’s be honest, we spend the majority 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?

What is Computer Vision Syndrome?

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

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

We all have 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 that we might think. 

What causes Computer Vision Syndrome?

What causes Computer Vision Syndrome?

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

Blue light overexposureThe 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), the most common symptoms of Computer Vision Syndrome are the following:

How is Computer Vision Syndrome diagnosed?

How is Computer Vision Syndrome diagnosed?

A vision specialist will be able to professionally diagnose CVS by performing a detailed eye examination that might include:

A check for untreated vision problems: typically a refraction is used in order to find out about any potential refractive error in the sight (such as astigmatism, farsightedness or nearsightedness).A test of visual acuity which will assess if your near or distance vision has been affected.A test to assess how the eyes work together:  whether they move in unison and if the focus is effective. 

Optometrists might also put special attention into how we set up our working space, including lighting, distance from the digital devices, posture and time spent in front of screens.

Is Computer Vision Syndrome permanent?

Most of the symptoms caused by Computer Vision Syndrome are only temporary. Normally, they tend to reduce or even disappear after taking a break from the use of digital devices. However, if nothing is done to prevent it, symptoms can become more serious and affect vision (such as blurred distance vision) over an extended period of time. 


How long does Computer Vision Syndrome last?

Most symptoms caused by CVS will go away a few hours after the person stops using their digital devices. However, if symptoms last longer, we recommend visiting an optometrist in order to prevent further visual discomfort.
