What Is Computer Vision Syndrome? Understanding the Impact of Screen Time on Your Eyes

If you’ve ever experienced tired, dry eyes after a long day staring at your computer, you’re not alone. With screens becoming an essential part of daily life—from working remotely to catching up on the latest Netflix series—our eyes are working overtime. Here in Matthews, North Carolina, we see it all the time: patients coming in with eye strain, headaches, and blurred vision, all signs of Computer Vision Syndrome (CVS). But what exactly is CVS, and how can you protect your eyes without giving up your digital life?

What Causes Computer Vision Syndrome?

CVS, also called digital eye strain, happens when your eyes work too hard to focus on digital screens for extended periods. Unlike reading a book or looking at printed materials, screens constantly refresh, have glare, and often display small, pixelated text that makes it difficult for our eyes to lock onto.\
 

A few factors that contribute to CVS include:

• Extended screen time – Hours of screen use without breaks

• Poor lighting – Harsh overhead lighting or excessive screen brightness

• Improper viewing distance – Holding a screen too close or too far away

• Reduced blinking – When staring at screens, we blink less, causing dryness and irritation
   

Common Symptoms of Computer Vision Syndrome

If you’re dealing with CVS, you might notice:

• Eye strain and discomfort

• Dry, red, or irritated eyes

• Blurred vision

• Headaches

• Neck and shoulder pain
   

Many of our patients in Matthews tell us they didn’t realize their constant headaches or tired eyes were connected to their screen time. However, there are ways to manage and even prevent CVS.
 

How to Reduce Eye Strain from Screens

You don’t need to quit your job or stop using your devices to find relief. A few small adjustments can make a big difference:

• Follow the 20-20-20 Rule – Every 20 minutes, look at something 20 feet away for at least 20 seconds. This gives your eye muscles a break.

• Adjust Your Screen Setup – Position your monitor about an arm’s length away and slightly below eye level.

• Use Proper Lighting – Avoid harsh overhead lights and try blue light filters on screens to minimize glare.

• Blink More Often – Make a conscious effort to blink frequently or use artificial tears if your eyes feel dry.

• Get Regular Eye Exams – An annual eye exam can help detect vision problems that might be making screen time even harder on your eyes.
   

When to See an Eye Doctor

If your symptoms persist despite making changes, it might be time to see an optometrist. At First Choice Eye Care, we can assess your vision, check for underlying conditions, and recommend customized solutions—whether that’s blue light filtering lenses, prescription glasses for screen use, or simple lifestyle adjustments.
