There are several ways to remove a foreign object from your eye. It’s important to see a doctor to remove a sharp object, such as a glass or metal fragment.
A foreign object in the eye is something that strikes your eye from outside your body. It can get underneath your eyelid, embed on the ocular surface, or penetrate your eye. It can be anything that does not naturally belong there, from a particle of dust to a metal shard.
When a foreign object strikes your eye, it will most likely affect the cornea or the conjunctiva.
The cornea is a clear dome that covers the front surface of the eye. It serves as a protective covering for the front of the eye. Light enters the eye through the cornea. It also helps focus light on the retina at the back of the eye.
The conjunctiva is the thin mucous membrane that covers the sclera, or the white of the eye. The conjunctiva runs to the edge of the cornea. It also covers the moist area under the eyelids.
A foreign object that lands on the front part of your eye cannot get lost behind your eyeball, but it may cause scratches, or abrasions, on the cornea.
These injuries usually are minor. However, some types of foreign objects can cause infection or damage your vision.
If you have a foreign object in your eye, you probably will have immediate symptoms. You may experience:
- a feeling of pressure or discomfort
- a sensation that something is in your eye
- eye pain
- extreme tearing
- pain when you look at light
- excessive blinking
- redness or a bloodshot eye
Cases in which a foreign object penetrates the eye are less common.

Many foreign objects can strike the cornea or conjunctiva of the eye as a result of mishaps that occur during everyday activities. Some of the most common types of these foreign objects are:
- dried mucus
- contact lenses
- metal particles
- glass shards
Dirt and sand fragments typically enter the eye because of wind or falling debris.
Sharp materials like metal or glass can get into the eye as a result of explosions or accidents with tools such as hammers, drills, or lawnmowers.
Foreign objects that enter the eye at a high rate of speed pose the highest risk of injury and permanent vision loss.
If you have a foreign object in your eye, prompt diagnosis and treatment will help prevent infection and potential loss of vision. This is especially important in extreme or intraocular cases.
Removing a foreign object yourself could cause serious eye damage. Get immediate emergency treatment if the foreign object:
- has sharp or rough edges
- is large enough to interfere with closing your eye
- contains chemicals
- was propelled into your eye at a high rate of speed
- is embedded in your eye
- is causing bleeding in your eye
If you have a foreign object embedded in your eye, or you’re helping someone with this problem, it’s important to get medical help immediately. To avoid further injury to the eye:
- Restrict eye movement.
- Bandage the eye using a clean cloth or gauze.
- If the object is too large to allow for a bandage, cover the eye with a paper cup.
- Cover the uninjured eye. This will help prevent eye movement in the affected eye.
You should also seek emergency treatment if the following symptoms are present after any type of object is removed:
- You still have a sensation of having something in your eye.
- You have abnormal vision, tearing, or blinking.
- Your cornea has a cloudy spot on it.
- The overall condition of your eye worsens.
If you suspect you have a foreign object in your eye, it’s important to get treatment promptly to avoid infection and the possibility of damaged vision. Take these precautions:
- Do not rub or put pressure on the eye.
- Do not use any utensils or implements, such as tweezers or cotton swabs, on the surface of the eye.
- Do not remove contact lenses unless there is sudden swelling or you suffered a chemical injury.
Take the following steps before starting any home care:
- Wash your hands.
- Look at the affected eye in an area with bright light.
- To examine the eye and find the object, look up while pulling the lower lid down. Follow this by looking down while flipping up the inside of the upper lid.
The safest technique for removing a foreign object from your eye depends on the type of object you’re trying to remove and where it’s located.
The most common location for a foreign object is under the upper eyelid. To remove a foreign object in this position:
- Immerse the side of your face with the affected eye in a flat container of water. While your eye is underwater, open and close your eye several times to flush out the object.
- The same results can be accomplished using an eyecup that you can purchase at a drugstore.
- If the object is stuck, pull out the upper lid and stretch it over the lower lid to loosen the object.
To treat a foreign object located beneath the lower eyelid:
- Pull out the lower eyelid or press down on the skin below the eyelid to see underneath it.
- If the object is visible, try tapping it with a damp cotton swab.
- For a persistent object, try to flush it out by flowing water on the eyelid as you hold it open.
- You also can try using an eyecup to flush out the object.
If there are many tiny fragments from a substance, such as grains of sand, you will have to flush out the particles instead of removing each one individually. To do this:
- Use a wet cloth to remove any particles from the area surrounding the eye.
- Immerse the side of your face with the affected eye in a flat container of water. While your eye is underwater, open and close it several times to flush out the particles.
- For younger children, pour a glass of warm water into the eye instead of immersing it. Hold the child’s face up and keep the eyelid open while you pour the water. This works best if one person pours the water while another holds the child’s eyelids open.
Contact a doctor if the foreign object in your eye has conditions that warrant emergency treatment or if:
- You did not succeed in removing the foreign object at home.
- Your vision remains blurred or otherwise abnormal after the removal of the foreign object.
- Your initial symptoms of tearing, blinking, or swelling persist and do not improve.
- The condition of your eye worsens despite the removal of the foreign object.
If you get treatment from a doctor, you may undergo an
- An anesthetic drop will be used to numb the eye’s surface.
- Fluorescein dye, which glows under special light, will be applied via an eye drop. The dye reveals surface objects and abrasions.
- The doctor will use a magnifier to locate and remove any foreign objects.
- The objects may be removed with a moist cotton swab, a pair of sterile tweezers, or flushed out with water.
If these initial techniques are unsuccessful at removing the object, the doctor may use needles or other instruments.
If the foreign object has caused a corneal abrasion:
- The doctor may give you an antibiotic ointment to prevent infection.
- For larger corneal abrasions, eye drops containing cyclopentolate or homatropine may be administered to keep the pupil dilated. Painful muscle spasms could occur if the pupil constricts before the cornea heals.
- You will be given acetaminophen to treat pain from larger corneal abrasions.
A CT scan or another imaging study may be required for further investigation of an intraocular foreign body.
You may be referred to a doctor who specializes in eye care, known as an ophthalmologist, for further assessment or treatment.
If you succeeded in removing a foreign object from your eye, your eye should begin to look and feel better
During this time, any significant pain, redness, or tearing should subside. An irritating sensation or minor discomfort may remain for a day or two.
The surface cells of the eye are restored quickly. Corneal abrasions caused by a foreign object usually heal in
However, infections are more likely if the foreign object was dirt particles, a twig, or any other object containing soil. Call a doctor if your symptoms aren’t improving.
Intraocular foreign bodies can result in endophthalmitis. This is an infection of the inside of the eye. If an intraocular foreign body damages the cornea or lens of your eye, your vision could be damaged or lost.
Foreign objects that may land in your eye accidentally during everyday activities can be difficult to anticipate or avoid.
Certain work or leisure activities are more likely to emit airborne objects that could land in your eye.
You can prevent getting a foreign object in your eye by wearing protective eyewear or safety glasses when you’re doing activities that could involve airborne objects.
To prevent getting a foreign object in your eye, always wear protective eyewear when:
- working with saws, hammers, grinders, or power tools
- working with dangerous or toxic chemicals
- using a lawn mower
It’s important to remove a foreign object from your eye as quickly as possible. Once it’s removed, your eye should feel better within a couple of hours. If the object scratched your cornea, it may take 1 or 2 days for your eye to heal.
