We live in a world where screens dominate our daily routines—whether it’s working on a computer, scrolling through social media, or unwinding with a favorite show. While technology has its benefits, our eyes are paying the price. If you’ve ever experienced dry, tired eyes, headaches, or trouble focusing after a long day of screen use, you may be dealing with Computer Vision Syndrome (CVS).
 

What is Computer Vision Syndrome?

Computer Vision Syndrome, also called digital eye strain, isn’t a single condition but a collection of symptoms caused by prolonged screen use. Unlike reading a book or looking at something in the distance, screens make our eyes work harder. We tend to blink less when staring at a screen, causing dryness and irritation. The constant shifting between digital text, glare from the screen, and blue light exposure all contribute to the strain.
 

Common Symptoms of CVS

If you spend hours in front of a screen, you might notice:

• Eye fatigue and discomfort – A burning or heavy sensation in the eyes.

• Blurred vision – Trouble focusing or seeing clearly after prolonged screen time.

• Dry eyes – A gritty or itchy feeling, often due to reduced blinking.

• Headaches – Often caused by constant refocusing and blue light exposure.

• Neck and shoulder pain – Poor posture from looking at screens at the wrong angle can strain your neck and upper body.
   

How to Protect Your Eyes from Digital Eye Strain

While cutting out screens isn’t realistic for most of us, making a few small changes can reduce the impact on your eyes.

• Follow the 20-20-20 rule – Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps relax your eye muscles.

• Adjust your screen settings – Increase text size, reduce glare, and use blue light filters to minimize strain.

• Blink more often – Make a conscious effort to blink to keep your eyes lubricated.

• Position your screen properly – Keep your monitor at eye level and about an arm’s length away.

• Use artificial tears – Lubricating eye drops can help combat dryness.
   

When to See an Optometrist

If your eye strain persists despite making adjustments, it may be time for a professional evaluation. Digital eye strain can sometimes mask underlying vision problems, such as uncorrected nearsightedness, farsightedness, or astigmatism. Additionally, specialized lenses, like blue light-blocking glasses or anti-fatigue lenses, can make a big difference.
