Computer Vision Syndrome: Signs You’re Spending Too Much Screen Time

If your eyes feel tired, dry, or strained after a long day at your computer, you’re not alone. In today’s digital world, many of us spend hours each day looking at screens - whether for work, school, or entertainment. Over time, this can lead to Computer Vision Syndrome (CVS), also known as digital eye strain. At Murryhill Eye Care, we see more patients experiencing screen-related vision problems than ever before. The good news is Computer Vision Syndrome is highly manageable with the right care and habits.
 

What Is Computer Vision Syndrome?

Computer Vision Syndrome refers to a group of eye and vision problems that result from prolonged use of digital devices such as computers, tablets, and smartphones. Unlike printed materials, screens add extra visual demands on your eyes. Glare, poor contrast, improper viewing distance, and reduced blinking all contribute to discomfort. While CVS is not typically permanent, ignoring the symptoms can significantly affect your comfort, productivity, and long-term visual health.
 

Common Signs You’re Spending Too Much Screen Time

If you regularly use digital devices, watch for these symptoms:

• Eye strain or fatigue
• Dry, irritated, or watery eyes
• Blurred or fluctuating vision
• Headaches
• Neck and shoulder pain
• Difficulty focusing when looking away from the screen

Many people notice their symptoms worsen in the afternoon or evening, especially after continuous screen use without breaks.
 

Why Screens Strain Your Eyes

Several factors make screens more demanding than reading a book:

• You blink less frequently while using digital devices, which leads to dryness.
• Blue light exposure can contribute to discomfort and disrupt sleep patterns.
• Poor posture and improper screen positioning increase muscular tension.
• Uncorrected vision problems become more noticeable during extended close-up work.

Even minor prescription changes can make a big difference in how your eyes feel after a full day of screen use.
 

When to See Your Eye Doctor

Occasional eye fatigue after a long day isn’t unusual. However, you should schedule an eye exam if:

• Your symptoms are persistent or worsening.
• Over-the-counter eye drops don’t provide relief.
• You experience frequent headaches.
• Your vision becomes blurry or double.
• You have trouble focusing when shifting between near and far objects.

Children and teens should also be evaluated if they spend significant time on screens and complain of discomfort, eye rubbing, or difficulty concentrating. An eye exam can determine whether digital eye strain is the issue - or if an underlying vision problem is contributing to your symptoms.

Protecting Your Eyes from Digital Strain

While professional care is essential, you can also reduce strain by:

• Following the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds)
• Adjusting screen brightness to match your surroundings
• Positioning your screen about an arm’s length away
• Keeping the top of your monitor at or slightly below eye level
• Remembering to blink regularly

Small changes can make a noticeable difference.
