Dry Eyes From Screens: Why It Happens and How to Get Relief
Dry eye happens when you don't make enough tears or they evaporate too fast, leaving your eyes stinging, gritty and blurry. Screens make it worse because you blink less. Blink on purpose, use artificial tears, and run a humidifier in dry weather. If it doesn't improve, see an eye doctor.
Symptoms of dry eye
- Stinging or burning eyes
- A scratchy, gritty feeling, like sand in your eye
- Blurry vision, especially when reading
- Redness and irritation
- Sometimes watery eyes — irritated eyes make extra tears
What causes it?
Screen time: when you focus on a screen, blinking drops from about 15 times a minute to 5–7. With fewer blinks, tears don't spread evenly and evaporate faster.
Age and sex: tear production drops with age, and dry eye is more common in women, especially after menopause.
Environment: wind, smoke, dry air and long hours in contact lenses all make it worse.
Medications and conditions: antihistamines, blood pressure medications, antidepressants and sleeping pills can contribute, as can Sjögren's syndrome, rheumatoid arthritis and thyroid disease.
Relief you can try at home
- Blink on purpose: slowly close and open your eyes now and then while using screens.
- Artificial tears: if you use them more than six times a day, choose preservative-free drops.
- Warm compresses: place a warm cloth on your eyelids and massage gently.
- Humidifier: add moisture to indoor air in dry seasons like winter.
- Block the wind: wear wrap-around glasses outdoors.
- Screen habits: take regular breaks and keep your phone 13–20 in (33–50 cm) away.
When to see an eye doctor
See an ophthalmologist if symptoms don't improve with home care or keep getting worse, if they interfere with daily life, or if you have significant pain or changes in your vision.
FAQ
Why do my eyes feel dry when I use screens?
You blink less — about 5–7 times a minute instead of 15 — so tears evaporate before they can spread across your eyes.
Can I use artificial tears often?
If you use them more than six times a day, choose preservative-free drops. If symptoms continue, see an eye doctor.
