If your eye hurts, the first step is figuring out whether it’s something you can manage at home or something that needs medical attention. Most eye pain comes from minor, treatable causes like dryness, strain, or a small scratch. But certain combinations of symptoms signal a problem that can damage your vision permanently if you wait too long.
Signs You Need Immediate Medical Care
Some types of eye pain are emergencies. Acute angle-closure glaucoma, for example, comes on suddenly and can cause permanent vision damage within hours if untreated. Get to an emergency room or urgent care eye clinic right away if your eye pain comes with any of the following:
- Sudden change in vision, including blurriness that wasn’t there before
- Seeing halos or circles around lights
- Severe headache, fever, or sensitivity to light alongside the pain
- Nausea or vomiting with eye pain
- A chemical splash or foreign object that hit your eye
- Swelling in or around the eye
- Inability to open or keep your eye open
If none of these apply to you, it’s likely safe to try some at-home steps first. But if the pain is getting worse over a few hours rather than better, don’t wait it out.
Figure Out What’s Causing the Pain
The right response depends on what’s behind the discomfort. Here are the most common culprits.
Dry Eyes
Dry eye pain usually feels like burning, stinging, or grittiness, as if something sandy is in your eye. It tends to get worse later in the day, in air-conditioned rooms, or after long stretches of screen time. Over-the-counter lubricating drops (artificial tears) are the standard first-line fix. If you need them more than four times a day, use preservative-free drops, which come in single-dose vials. Preserved drops in multi-dose bottles are fine for occasional use, but the preservatives can irritate already-dry eyes with frequent application.
Thicker gel drops and ointments are also available over the counter for more stubborn dryness. Gels can blur your vision temporarily, so many people save them for bedtime.
A Scratch on the Eye
A corneal abrasion, or scratch on the clear surface of your eye, causes sharp pain, watering, redness, and a strong feeling that something is stuck in your eye. This commonly happens from a fingernail, a branch, or debris blown into the eye. Minor scratches typically heal within 24 to 48 hours because the cells on the eye’s surface reproduce very quickly. Larger scratches take longer.
If you suspect a scratch, avoid rubbing your eye. You can rinse it gently with clean water or saline. If the pain doesn’t improve within a day, see an eye doctor. They’ll use a yellow dye called fluorescein that fills in any break on the eye’s surface, making even tiny scratches easy to spot under a special microscope. They may also flip your eyelids to check for trapped debris underneath.
Eye Infections
Conjunctivitis (pink eye) is the most common eye infection. Viral conjunctivitis tends to produce watery discharge and often starts in one eye before spreading to the other. Bacterial conjunctivitis typically causes thicker, yellowish or greenish discharge that can crust your eyelids shut overnight. Mild viral cases usually clear on their own in a week or two. Bacterial infections with heavy discharge, significant swelling, or pain need antibiotic drops from a doctor.
A more severe form, hyperacute bacterial conjunctivitis, causes massive discharge, significant swelling, pain, and decreased vision. This is not something to treat at home.
Screen-Related Strain
Digital eye strain produces a dull ache behind or around the eyes, often paired with tired-feeling eyes, headaches, and blurred vision after hours of close-up work. The fix is simple: follow the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds. This lets the focusing muscles in your eyes relax. It won’t cure an underlying condition, but it prevents the fatigue that comes from sustained close focus.
Contact Lens Problems
If your eye hurts and you wear contacts, take them out. Contact lenses are one of the most common causes of keratitis, an infection or inflammation of the cornea that can become serious. The risk is highest if you sleep in your lenses, wear them longer than recommended, skip proper disinfection, or swim while wearing them. Extended-wear contacts carry more risk than daily disposables. If removing your lenses doesn’t relieve the pain within a few hours, or if you notice increasing redness, light sensitivity, or blurry vision, see an eye care provider before putting contacts back in.
First Aid for Chemical Exposure
If a chemical splashed into your eye, start flushing immediately. Don’t wait to get to a hospital. Tilt your head so the affected eye is lower than the other (this prevents the chemical from draining into your good eye), and pour clean water steadily across the eye from the nose side outward. Blink frequently during flushing and look in different directions so the water reaches all surfaces, including under the lids.
Keep flushing for at least 30 minutes. Guidelines recommend using one to three liters of water at minimum, and in severe cases, much more may be needed. Continue flushing on the way to the emergency room if possible. Speed matters more than technique here: the sooner you start diluting the chemical, the better the outcome.
Warm Compress vs. Cold Compress
Both work, but for different problems. A warm compress is best for styes, blocked oil glands in the eyelids, and the crusty buildup that comes with eyelid inflammation (blepharitis). Many cases of dry eye are actually caused by clogged oil glands along the eyelid margin. The warmth needs to raise the eyelid temperature to about 40°C (104°F) for around five minutes to soften the solidified oils and unblock the gland openings. A clean washcloth soaked in warm water works, though it cools quickly, so you’ll need to re-soak it a few times.
A cold compress is better for allergic reactions, puffy swollen lids, and the irritation that comes from things like pollen or pet dander. The cold reduces swelling and soothes the itch. A bag of frozen peas wrapped in a thin cloth, or a chilled gel pack, applied for 10 to 15 minutes will help.
What Not to Do
A few instincts make eye pain worse. Don’t rub your eye, especially if something might be scratching the surface. Don’t try to remove an embedded object yourself. Don’t use redness-reducing eye drops as a long-term fix: they constrict blood vessels temporarily but can cause rebound redness and mask symptoms of a real problem. And don’t put in contact lenses when your eye is already painful or red, even if you think it’s “just dryness.”
If over-the-counter drops and home care don’t bring noticeable improvement within a day or two, or if the pain keeps returning, an eye exam can catch problems like early infections, increased eye pressure, or inflammation inside the eye that you can’t diagnose by feel alone.
