What is Computer Vision Syndrome?

Many of us spend many hours a day looking at screens, for our jobs and when we’re relaxing watching tv or scrolling through social media. 


But, staring at screens can cause Computer Vision Syndrome, which is an umbrella term for types of eye strain caused by prolonged use of digital screens.[1]

What are the symptoms of Computer Vision Syndrome? 


Symptoms of Computer Vision Syndrome include: 



  • Blurred vision 
  • Double vision
  • Dry, red eyes 
  • Eye irritation
  • Headaches
  • Neck or back pain. [2]

How does screen use cause Dry Eye Syndrome?


Dry eyes are a key symptom of Computer Vision Syndrome. Our eyes need to stay moist to be healthy and blinking helps cover the eyes with a lubricating layer called the tear film. [3]

When we stare at digital devices, we blink less often. Therefore, the longer we spend looking at screens, the dryer our eyes become.


A recent study of Japanese workers even goes as far as to suggest that working on screens for an extended period of time can change the composition of your tears, potentially causing chronic Dry Eye Syndrome. [4]



Tips to avoid Computer Vision Syndrome


  • Reduce screen time.


One of the most effective ways to reduce eye strain and dry eyes due to staring at screens is to cut down your screen time. Limiting how many hours a day you spend looking at digital devices can help protect against itchy, dry eyes.



  • Follow the 20:20:20 rule



Every 20 minutes, try to look at something 20 feet away for 20 seconds. 20 seconds is long enough for your eyes to fully relax, so doing this frequently when you are looking at your screen is a great way to keep your eyes in a healthy condition. [5]

  •      Adjust your monitor


If you are using a monitor, try putting it directly in front of you, about an arm’s length away, just below eye level. This way the eyes can see the screen without being overly strained. [6]

  •       Make the text bigger


Making the text bigger on your phone, laptop or tablet makes it easier to see, reducing the likelihood of Dry Eye symptoms developing. [7]

  •    Find the right lighting


Bright lights that reflect back into your eyes can often make screen associated Dry Eye much worse. Softer background lighting is better for your eyes, and also creates a calm environment. [8]

  • Use a humidifier


This is a great tip, especially for people who work from home. A humidifier adds moisture to the air in the room, helping to prevent Dry Eye. [4]



  •        Use an app


This is a useful way to limit screen use in your downtime as well as work time. Software like f.lux automatically adjusts the brightness and tone of your screen to protect your eyes. And apps like Time Out remind you to take regular breaks from your device. [9]



  •      Use a lubricating eye drop
