If something is stuck in your eye, resist the urge to rub it. Instead, wash your hands, then try blinking several times to let your tears push the particle out naturally. If that doesn’t work, flush your eye with a gentle stream of clean, lukewarm water for about a minute. Most loose debris like dust, sand, or an eyelash will wash out easily, and any minor scratch it left behind typically heals within 24 to 48 hours.
How to Flush Your Eye Safely
Start by washing your hands with soap and water so you don’t introduce new bacteria. Then choose one of these flushing methods:
- Eyecup or small glass: Fill a clean drinking glass or eyecup with lukewarm water. Rest the rim on the bone at the base of your eye socket, tilt your head back, and let the water flow over your open eye.
- Shower method: Stand under a gentle stream of lukewarm water aimed at your forehead, just above the affected eye. Hold your eyelid open and let the water run down across the eye.
- Medicine dropper: If the object is floating on the surface of your eye, a medicine dropper filled with clean warm water can be enough to rinse it free.
For a simple piece of debris, about a minute of flushing is enough. If you wear contact lenses, remove them before or during flushing. A contact lens can trap particles against the surface of your eye, making the irritation worse and increasing your risk of a scratch.
If Someone Else Needs Help
Seat the person in a well-lit area and wash your hands first. Pull their lower lid down gently and ask them to look up so you can scan the lower part of the eye. Then hold the upper lid while they look down. If you can see the object floating on the tear film, flush it out with a dropper or a gentle stream of water from a glass. Never try to pick out a particle with your fingers or any tool.
For young children who can’t follow directions, the shower method often works best because it doesn’t require them to hold still in a precise position. Lay them back, aim lukewarm water across the forehead, and let gravity carry it over the open eye. Having a second adult hold the child’s head steady helps.
Why Rubbing Makes Everything Worse
Rubbing feels instinctive, but it’s the single most damaging thing you can do. When you rub, you press the foreign particle harder against the cornea, the clear front surface of your eye. This can create tiny scratches you won’t see but will definitely feel, as a sharp, stinging pain that gets worse when you blink.
Rubbing also pushes bacteria and smaller particles from your hands into the eye, raising the chance of infection. Over time, repeated rubbing can thin the cornea, loosen the collagen in your eyelids, and even cause the cornea to bulge in a way that permanently changes your vision. In children, this risk is especially high because their corneal tissue is still developing.
Chemical Splash: A Different Emergency
If a chemical, not just debris, gets into your eye, the flushing rules change dramatically. Begin rinsing immediately with clean water or saline and keep going for at least 15 to 30 minutes. Don’t stop to look up instructions or drive to the ER first. Continuous flushing is the single most important thing you can do to limit the damage from acid or alkali burns. After flushing, seek emergency care right away.
Water vs. Saline for Flushing
Sterile saline is the ideal choice because it matches your body’s natural fluids and carries no microorganisms. But in an emergency, clean tap water is perfectly fine and far better than doing nothing. The risk worth knowing about: tap water can contain a microscopic amoeba that causes a rare but serious corneal infection. Contact lens wearers are especially vulnerable. If you flush with tap water, remove your lenses first and follow up with your eye care provider if irritation persists beyond a day.
What Not to Do With Embedded Objects
If the object is large, visibly stuck in the eye, or protruding between the lids, do not try to pull it out. Don’t press on the eye or apply any pressure. Attempting removal can push the object deeper or cause the eye’s contents to leak. Instead, loosely cover the eye (without pressing) and get to an emergency room. Even materials that seem harmless, like a small shard of glass or a metal filing, can penetrate deeper than they appear from the surface.
What a Corneal Scratch Feels Like
Even after the foreign body is gone, you may feel like something is still in your eye. That’s a corneal abrasion, a scratch on the eye’s surface. Common symptoms include sharp pain, tearing, redness, sensitivity to light, and blurry vision in the affected eye. The cells on the cornea regenerate quickly, and most minor scratches heal on their own within one to two days. Larger scratches can take longer.
Don’t reach for redness-relieving eye drops from the pharmacy. These can actually increase pain on a scratched cornea and won’t speed healing. There are no over-the-counter drops designed to treat eye scratches. If your eye care provider confirms an abrasion, they may prescribe antibiotic drops to prevent infection, lubricating drops for comfort, or anti-inflammatory drops to reduce scarring. Preservative-free artificial tears are generally safe for mild dryness in the meantime.
If your symptoms aren’t improving after three days, or if they’re getting worse at any point, that’s a sign the scratch may be infected or more extensive than it first seemed. Untreated infections can lead to scarring and permanent vision loss.
Signs You Need Emergency Care
Most foreign-body-in-the-eye situations resolve at home with simple flushing. But certain symptoms signal something more serious:
- Partial or total vision loss in the affected eye
- A visible wound on or near the eye
- Blood visible inside the eye or leaking from it
- Clear fluid leaking from the eye
- An object embedded in the eye that won’t flush out
- Chemical exposure, including fumes
- Persistent severe pain that doesn’t improve after flushing
Any of these warrants an emergency room visit, not a wait-and-see approach. Eye injuries can deteriorate quickly, and what feels minor on the surface can involve deeper structures that only a proper examination will reveal.
