Having something lodged in your eye is never pleasant, regardless of the size or origin of the debris. Whether you have a spec of dust or some small foreign particle stuck in your eye, it is important that you take steps to clear it out and avoid damaging your eye.

Avoid rubbing your eyes. It is often instinctual to rub your eye when something has gotten into it, but this can actually be quite dangerous. If you rub your eye, the trapped particle will be pushed into your eye under the lid, possibly scratching the cornea. If this occurs, permanent eye damage may occur, along with a lot of pain. Try not to apply pressure or rub your eyes at all, to avoid this.

Blink your eyes rapidly. Although it can certainly be very uncomfortable to have dust, hair, or another small item stuck in your eye, your body’s natural response of blinking is the best way to clear it out. Blink rapidly to help move the debris, and allow any tears that may form to clear it out. The more you blink and cry, the better chance you have of removing the particle. Although you may feel silly crying, the tears will naturally wash out the debris.

Pull out your eyelids. Sometimes, a small item may get stuck in your eye and then trapped under the lid. You should attempt to remove it by blinking first, and then pull out the lid and blink some more. This should move the debris out from under your lid as you blink, but the process can be repeated if it doesn’t work at first.

Rinse your eyes with water. If you have an eye cup (used for rinsing eyes), use that to wash out your eyes with cool, clean water. Otherwise, use a small bowl or cup full of water and splash the water into your open eye. You can also place your open eye under a gently-pouring faucet to rinse it out. The water won’t damage your eyes at all, so don’t be afraid to open your eyes to get water in them.

Use a swab or damp cloth on your eyes. Sometimes, it may be easier to directly wipe an item out of your eyes if you can see it easily (such as a spec of dirt). Dampen a small cotton swab, tissue, or cloth with clean water, and gently press (don’t rub!) the swab onto the spot in your eye. Be careful of rubbing or applying pressure to the cornea, as this is the most sensitive and will cause the most pain when touched. If your cloth/swab was white, you should be able to see when the debris has been removed.

Have a friend help you. If you’re having difficulty getting the particle out of your eye and can’t see it in a mirror, you should turn to a friend for help. Lift up your eyelids and have them look to see where the debris is. If you are comfortable with it, you may want to have them use a cotton swab to dab the item out of your eyes. Otherwise, rinse out your eyes with water to try to remove it.

Use eye drops. The purpose of eye drops is to flush the eye in the absence of tears or water. If you can’t seem to cry and blink out the debris, you can add a few drops of an eye solution to help hasten the process. Follow the bottle directions for your eye drops to determine how much to place in each eye.
