Likely cause
High screen time can cause digital eye strain, which is a common reason for eye discomfort. When we use phones or computers for long periods, we blink less often, causing the eyes to become dry, tired, and irritated. This may lead to eye pain, burning, watering, blurred vision, headaches, or difficulty focusing. However, screen time is not the only possible cause. Eye pain can also occur due to dry eyes, an uncorrected glasses number, eye infection, allergies, sinus problems, or other eye conditions. If the pain is severe, affects only one eye, or doesn't improve with rest, you should have your eyes examined.
What to watch for
Monitor whether the pain improves after resting your eyes or becomes worse over time. Also note if you have redness, swelling, discharge, blurred or double vision, light sensitivity, severe headache, nausea, fever, or pain while moving the eye. These symptoms are not typical of simple digital eye strain and may indicate an eye disease that needs prompt evaluation. If you wear glasses or contact lenses, pay attention to whether your vision has changed, as an outdated prescription can also contribute to eye strain and headaches.
What you can do
Follow the 20-20-20 rule: every 20 minutes, look at something about 20 feet away for at least 20 seconds. Blink consciously while using screens to keep your eyes moist. Keep the screen about an arm's length away, slightly below eye level, and adjust the brightness so it matches the room lighting. Avoid using screens continuously for long periods and take short breaks every hour. Stay well hydrated, get adequate sleep, and avoid rubbing your eyes. If you wear glasses, make sure your prescription is up to date. If symptoms continue despite these measures, arrange an eye examination.
When to see a doctor
See an eye doctor if the pain lasts for more than a few days despite reducing screen time, keeps coming back, or is associated with blurred vision or frequent headaches. Seek urgent medical attention immediately if you develop sudden loss of vision, severe eye pain, redness with light sensitivity, pain after an eye injury, chemical exposure, swelling around the eye, or persistent vomiting with severe eye pain. These symptoms may indicate a serious eye condition that requires prompt treatment to protect your vision.
