Most loose debris in your eye, like an eyelash, dust, or a grain of sand, can be removed at home in a few minutes using nothing more than clean water and your own tears. The key is resisting the urge to rub, which can drag the particle across your cornea and scratch it. Here’s how to handle it safely, step by step.
What Not to Do
Before anything else, keep your hands away from your eye. Rubbing feels instinctive, but it’s the single fastest way to turn a minor irritation into a painful corneal scratch. A small speck of dust or grit pressed and dragged across the surface of your eye can leave an abrasion that hurts far worse than the original particle. Repeated or forceful rubbing can also weaken and distort the cornea over time, a condition called keratoconus.
A few other things to avoid:
- Don’t use tweezers, toothpicks, or anything sharp near the surface of your eye.
- Don’t try to remove an object that’s embedded or stuck in the eye. Leave it in place and get medical help.
- Don’t touch the eye with dry cotton balls or tissue fibers, which can shed and add more debris.
Step 1: Let Your Eye Try to Fix Itself
Your body’s first response to a foreign object is a flood of tears, and that’s exactly what you want. Blink rapidly several times. This encourages your tears to wash the particle toward the inner corner of your eye, where it can drain naturally. Many small, loose particles come out on their own within a minute or two of steady blinking.
If blinking alone isn’t working, gently pull your upper eyelid outward and down over your lower eyelid. This lets the lower lashes brush the underside of the upper lid and can dislodge particles trapped there.
Step 2: Flush With Clean Water or Saline
If blinking doesn’t clear the debris, flushing is the next step. A sterile saline eyewash from a drugstore is the safest option. Tilt your head so the affected eye is facing down and to the side, then let the solution flow gently across the eye from the inner corner outward. You can also use a small, clean cup or an eyecup filled with saline, pressing it against the rim of your eye socket and tilting your head back to let the fluid wash over the surface.
If you don’t have saline available, clean running water works in a pinch. Cup your hands under a gentle stream from the faucet and splash it into your open eye, or stand under a shower and let lukewarm water run over your forehead and into the eye. Tap water does carry low levels of bacteria that are harmless when swallowed but can occasionally cause eye infections, so switch to a store-bought sterile eyewash when you can. Never use homemade saline solutions in your eyes.
Step 3: Check Under the Upper Eyelid
If you still feel something after flushing, the particle may be hiding under your upper lid. This is common, and you can check it yourself. Place a cotton-tipped swab horizontally across the outside of your upper eyelid, then gently flip the lid upward over the swab. Look in a mirror (or have someone else look) for the particle. If you can see it sitting on the surface, use a damp cotton swab or the corner of a clean, damp cloth to gently lift it off. Don’t drag or scrape.
If You’re Wearing Contact Lenses
Remove your contact lens before you start flushing. A particle trapped between a lens and your cornea can cause more friction and damage with every blink. Wash your hands, take the lens out, then follow the steps above. Once the debris is cleared, inspect your lens for damage before reinserting it. If your eye is still red or sore, leave the lens out and wear glasses until the irritation fully resolves.
What a Chemical Splash Requires
Getting a chemical in your eye is a different situation from a loose particle, and speed matters far more than precision. Start flushing immediately with whatever clean water is available: a faucet, a shower, a garden hose, a water bottle. Hold your eye open and let the water run continuously. Don’t stop after a few seconds. Clinical guidelines recommend irrigating with several liters of fluid, and in serious exposures, up to 20 liters may be needed. Keep flushing until you can get to an emergency room or until first responders arrive. Alkaline substances (like oven cleaner, concrete dust, or drain opener) penetrate eye tissue more deeply than acids and require especially prolonged flushing.
The Feeling May Linger After Removal
Even after the particle is completely gone, your eye may still feel scratchy, watery, or sore. That’s usually a superficial corneal abrasion, a tiny scratch on the clear front surface of your eye. Symptoms include redness, tearing, blurred vision, and sensitivity to light. Minor abrasions heal quickly because the cells in the cornea reproduce faster than almost anywhere else in your body. Most people feel significantly better within 24 to 48 hours. Larger scratches take longer.
During recovery, avoid rubbing the eye and stay away from contact lenses until the discomfort is completely gone. Artificial tears (lubricating eye drops) can ease the gritty feeling while the surface heals.
Signs You Need Medical Help
Most foreign-body episodes resolve at home, but some situations need professional care. Get medical attention if:
- The object is embedded in the eye or won’t come out with flushing.
- You notice any change in your vision, even slight blurriness.
- Pain, redness, or the sensation of something still in your eye persists for more than 24 hours after you’ve removed the particle.
- The object entered your eye at high speed, such as from grinding metal, using power tools, or an explosion. High-velocity fragments can penetrate the surface of the eye even when the injury looks minor from the outside.
An eye doctor can examine the surface with a special dye and a magnifying lamp to find scratches or embedded fragments that aren’t visible to the naked eye. If something is stuck, they have the sterile instruments to remove it safely without causing further damage.
