If your eyes feel dry, tired, or achy by the end of a workday full of screens, you’re not imagining it. This combination of eye strain and dry eyes — sometimes called digital eye strain or computer vision syndrome — is one of the most common complaints I hear in clinic, and it’s becoming more common as screen time increases across all ages.
Why screens are hard on your eyes
When we focus on a screen, we blink far less often, sometimes by half the normal rate. That means your eyes dry out faster. On top of that, screens require constant small adjustments in focus, and glare or poor contrast forces your eye muscles to work harder than they would reading printed text.
Common Symptoms of Eye Strain and Dry Eyes
Watch for dryness or a gritty feeling, blurred vision that comes and goes, headaches centered around the eyes or temples, and neck or shoulder tension from leaning toward the screen.
What actually helps
The 20-20-20 rule is still the single best habit: every 20 minutes, look at something 20 feet away for at least 20 seconds. Beyond that, consciously blink more often, keep screens about an arm’s length away and slightly below eye level, and adjust room lighting so it doesn’t compete with your screen’s brightness. If dryness is a persistent issue, preservative-free artificial tears used a few times a day can make a real difference.
When to get it checked
Occasional strain is normal, but if symptoms persist even with good habits, it’s worth having your prescription and eye surface checked. Uncorrected refractive errors and early dry eye disease both masquerade as “just screen fatigue,” and both are easy to treat once identified.
Screens aren’t going away, but with a few consistent habits, your eyes don’t have to pay the price for it.
