Do You Have CVS? Screen Time Could Be Affecting Your Vision sakkmesterke/Fotolia

Do you ever wonder if staring at a computer screen is making your eyes tired or dry?  If so, you might have computer vision syndrome.

In the current age of technology, most of us spend hours every day staring at one digital screen or another.  Time spent on the computer, texting on the phone, reading a book on an e-reader or tablet, or just watching TV all count as screen time. 

Too much screen time can lead to CVS, which is also sometimes called digital eye strain. CVS is a collection of various eye and vision-related problems, rather than one specific condition. 

Symptoms of CVS include:

  • Tired or strained eyes
  • Headaches
  • Blurry vision
  • Dry or irritated eyes
  • Double vision
  • Pain in the neck or shoulders

CVS occurs because your eyes have to work harder to focus on a computer or other type of screen than they do focusing on other objects. 

This is especially true when you compare reading from a screen and reading from a printed page.  In general, words in print are clearer and have better contrast between dark print and white paper.  

Text on a computer screen may be slightly fuzzy, even if you don’t realize it.  And computer text is often a shade of grey or another color rather than black, which means there is less contrast between the text and the background.

Working on a computer also forces your eyes to track back and forth and to constantly change focus as you look from the screen to paperwork on your desk and back to the screen. 

Depending on your screen, your eyes may also have to work around flicker and glare from other light sources.

If you need glasses but don’t wear them or if your prescription is out of date, you may be more prone to CVS. 

Getting older also makes it harder for your eyes to focus on the screen as the lens of the eye becomes less flexible with age.

But you don’t have to be an adult to develop CVS.  Children who spend too much time watching TV, playing games on a tablet or phone, or working on a computer can also develop CVS.

Here are some things you can do to protect your vision and reduce CVS symptoms:

Adjust your space 

Make sure your computer monitor is slightly below eye level to reduce neck strain.  Use a stand to hold papers next to your monitor so you don’t have to look up and down as much while you work.

There are a new set of reading glasses on the market that combat computer vision syndrome. If you use reading glasses and find they are not comfortable when using your computer you should look into SightLine readers at www.sightlinereaders.com. Plus, these readers are stylish!
