Digital eye strain is real — and almost universal among knowledge workers and students. The fix isn't stopping screens; it's understanding what actually causes strain and addressing it directly.
What's happening
The real culprits.
When you focus on a screen, you blink 30–60% less — your tear film evaporates. Your focusing muscles stay contracted for hours. Any uncorrected Rx quietly adds strain.
The fixes are simple and evidence-based: regular distance breaks, intentional blinking, appropriate correction, and ergonomics. Blue-light glasses aren't part of this list — research doesn't support them.
What helps
Here's the plan — and why it works.
Breaks
The 20-20-20 rule
Every 20 minutes, look 20 feet away for 20 seconds. Works. Free.
Moisture
Artificial tears
Keep on your desk. Use them before your eyes feel dry, not after.
Even small uncorrected Rx creates strain over hours. Annual exam catches this.
Persistent strain isn't normal
If eyes hurt daily despite good habits, that's a signal. Uncorrected vision, hidden dry eye, or convergence issues could be the real cause — and all are treatable with a proper exam.
Common questions
Honest answers to common questions.
Why do my eyes hurt after a Zoom-heavy day?+
Sustained close focus + reduced blinking + screen brightness + uncorrected Rx = perfect strain storm. Your eyes adapt for hours then protest.
Do blue light glasses help?+
Research says no. The American Academy of Ophthalmology and most research bodies don't recommend them for eye strain. The causes of strain are blinking, focus, and Rx — none of which blue light affects.
What's the best screen distance?+
Arm's length from a desktop — about 20–28 inches. Laptop closer than ideal for ergonomics; consider an external monitor or keyboard for long sessions.
Should I use larger text?+
Yes. Most default text sizes are too small for comfortable extended reading. Zoom in — your eyes will thank you.
When should I come in?+
If strain persists despite good habits, you probably need a Rx check, dry eye treatment, or computer-specific glasses. An exam can transform screen-heavy days.
