Something Stuck in Your Eye (Foreign Body)
Signs and Symptoms of a Foreign Body
When a foreign object enters your eye, you will usually feel it right away. The sensation can range from a slight scratchy feeling to sharp, stabbing pain depending on what got into your eye and where it landed.
- A gritty or sandy sensation that gets worse when you blink
- A feeling that something is stuck under your eyelid
- Sharp pain that may worsen with eye movement
- Increased tearing as your eye tries to flush out the object
- Sensitivity to light and a strong urge to keep your eye closed
Foreign bodies can interfere with your vision in several ways. You might notice that your sight becomes less clear, usually from excess tearing or from the object blocking part of your line of sight.
Most blurring improves quickly once we remove the object and your eye begins to heal. However, if you notice persistent vision loss, new flashes of light, many new floaters, or a curtain or veil blocking part of your vision, seek urgent evaluation right away, as these symptoms may indicate a more serious problem affecting the back of your eye.
Certain symptoms indicate a more serious problem that requires urgent evaluation. If you experience any of these red flags, contact our office right away or seek emergency care.
- Significant vision loss or sudden changes in your ability to see
- Blood layering behind the clear front surface of your eye, a condition called hyphema, or any eye bleeding after trauma
- High-velocity metal-on-metal injury from grinding, hammering, or explosion
- Suspected penetrating injury with a visible object stuck in your eye, misshapen or peaked pupil, fluid leaking from the eye, or suddenly very low vision
- Severe light sensitivity with worsening pain, especially if you wear contact lenses
- New flashes of light, many new floaters, or a curtain or veil blocking part of your vision
- Chemical exposure to your eye, especially alkali or unknown substances
- Deep or penetrating pain that does not improve with flushing
- A foreign body that appears embedded in your eye or will not wash out
Sometimes your eye continues to feel uncomfortable even after a foreign body has been removed or washed away. This ongoing irritation happens because the object may have scratched the surface of your eye, a condition called a corneal abrasion.
Your cornea has many nerve endings, so even a tiny scratch can cause significant discomfort. The scratched area needs time to heal, and you may feel a foreign body sensation, tearing, and light sensitivity for a day or two after the actual object is gone. If symptoms persist beyond a few days or worsen, we need to examine your eye to rule out infection or a remaining fragment.
What Can Get Stuck in Your Eye and Why
The most common foreign bodies are small particles from your everyday environment. Dust and dirt can blow into your eye on a windy day, while sand often causes problems at the beach or in dry climates.
Even your own eyelashes can become foreign bodies if they fall into your eye or grow in the wrong direction. These everyday particles usually sit on the surface of your eye or under your eyelid and can often be safely flushed out with clean water or saline.
Certain jobs and hobbies create higher risks for eye foreign bodies, especially those involving grinding, cutting, or sanding. Metal shavings, wood chips, and fiberglass fragments can fly into your eye at high speed and may embed themselves in the cornea.
- Metal fragments from grinding, welding, or hammering on metal surfaces
- Wood particles from sawing, drilling, or woodworking projects
- Fiberglass splinters from insulation work or boat repair
Chemical splashes during cleaning or industrial processes are a separate category of eye emergency, not foreign bodies. Chemicals require immediate continuous irrigation and urgent medical evaluation, which we discuss in the treatment section below.
Spending time outdoors exposes your eyes to various natural foreign bodies. Wind can carry pollen, plant debris, and tiny insects into your eyes, while sports activities may introduce grass clippings or dirt.
Outdoor work like gardening, mowing lawns, or yard maintenance increases your exposure to airborne particles. Activities near water can lead to sand or small organisms entering your eye. Wearing protective eyewear during these activities significantly reduces your risk of eye foreign bodies.
Anyone can get something stuck in their eye, but certain groups face higher risks based on their work and daily activities. People who work in construction, manufacturing, or automotive repair encounter foreign bodies more frequently than office workers.
- Construction workers and tradespeople who use power tools
- Factory and warehouse workers in dusty environments
- Landscapers and agricultural workers
- Mechanics and metalworkers
- People who wear contact lenses, which can trap particles against the eye
How We Diagnose and Examine Foreign Bodies
When you visit our office with a suspected foreign body, we start with a thorough evaluation of your symptoms and how the injury happened. We will ask you to describe what you felt and when the problem began.
Next, we carefully examine both of your eyes, even if only one feels affected. We check your vision, look at the surface structures, and gently flip your eyelids to check for hidden objects. Throughout the exam, we take care to keep you comfortable while ensuring we find any foreign material that may be present.
Our office uses specialized equipment to locate foreign bodies that might be invisible to the naked eye. A slit lamp microscope allows us to magnify your eye and examine it in fine detail under controlled lighting.
- Slit lamp biomicroscope for magnified viewing of eye structures
- Bright handheld lights to illuminate the eye surface from different angles
- Special eyelid retractors to examine hidden areas under the lids
- Magnifying loupes for enhanced visualization during removal procedures
One of the most valuable diagnostic tools we use is fluorescein dye, an orange liquid that temporarily stains damaged areas of your cornea. We place a small drop or strip of fluorescein in your eye, and it spreads across the surface with your tears.
When we shine a blue light on your eye, any scratches or abrasions glow bright green, making them easy to see and evaluate. This technique also helps us identify foreign bodies and determine whether they have caused damage to the corneal surface. The fluorescein washes away naturally with your tears and usually clears within minutes to an hour.
Not all foreign bodies are easy to spot, even with our specialized equipment. Very small particles, clear or translucent objects, and items hidden under the upper eyelid can evade detection during initial examination.
Some foreign bodies burrow into the surface tissues and become covered by cells, making them nearly invisible without close inspection. In rare cases, objects may penetrate deeper into the eye, requiring additional imaging tests to locate them. When we suspect an intraocular foreign body, we often order urgent CT imaging of the orbit. We avoid MRI when a metallic foreign body is possible, as the magnetic field can move metal inside the eye and cause severe damage. If your symptoms suggest a foreign body but we cannot find one during the first visit, we may schedule additional examinations or imaging to ensure nothing was missed.
Treatment Options for Foreign Bodies
For minor foreign bodies like dust or eyelashes, gentle irrigation at home may safely remove the particle. The key is to use sterile saline or clean water and avoid applying pressure or rubbing your eye.
- Wash your hands thoroughly before touching your face or eye area
- Remove contact lenses if you are wearing them
- Prefer sterile saline or preservative-free artificial tears when available; avoid tap water exposure if you wear contact lenses, as tap water carries a higher risk of serious eye infection
- Tilt your head to the side and gently pull down your lower eyelid
- Use a clean cup or bottle of sterile saline to flush the solution gently across your eye, or use clean running water if sterile saline is not available
- Avoid using redness relief drops or contact lens solution to rinse the eye
- Blink several times to help the tears move the particle toward the corner
- If the object does not come out after two or three gentle attempts, stop and call our office
Home irrigation works well for loose surface particles, but you should not attempt to remove certain foreign bodies yourself. Recognizing when to seek professional help protects your eye from further injury.
Never try to remove an embedded object with tweezers, cotton swabs, needles, or any other tool at home, and do not press on your eye. Stop trying to remove the object at home if it appears stuck to your eye, if you see it embedded in the surface, or if flushing causes increasing pain. Also seek our care if the foreign body is metal or glass, if your symptoms worsen, or if you develop new problems like vision changes or severe redness.
If you suspect a penetrating injury or high-velocity impact (such as metal-on-metal hammering or grinding), do not attempt any removal. Protect the eye with a rigid shield if possible and go to emergency care immediately.
Chemical exposures are a separate emergency. Begin immediate continuous irrigation right away with clean water or saline and continue flushing during transport to emergency care, especially for alkali or unknown chemical exposures.
When a foreign body requires professional removal, we use several proven techniques depending on the type and location of the object. First, we apply numbing drops to ensure your comfort during the procedure.
For surface objects, we may use a sterile cotton swab or irrigation to gently lift the particle away. Embedded foreign bodies often require careful removal with a specialized needle or burr under the magnification of our slit lamp. These instruments are designed for professional use only and should never be used at home. Throughout the process, we work slowly and precisely to minimize any additional trauma to your eye.
After we remove a foreign body, we treat any damage it caused to your cornea. Superficial scratches usually heal on their own within 24 to 48 hours, but deeper abrasions may need additional care.
- Antibiotic eye drops or ointment to prevent infection during healing
- Lubricating drops to keep the eye surface moist and comfortable
- Pain relief through oral medications if the discomfort is significant
- Close monitoring for signs of infection or slow healing
Eye patching is generally not recommended for uncomplicated corneal abrasions, as it does not speed healing and may increase discomfort. For certain injuries, especially contaminated wounds or penetrating trauma, we may also review and update your tetanus immunization status as part of standard care.
Based on the type of foreign body and any resulting injury, we may prescribe several types of medication to support healing. Antibiotic eye drops are standard after foreign body removal to prevent bacterial infection, especially if the cornea was scratched. Contact lens wearers often need antibiotics with broader coverage against specific bacteria and require closer follow-up.
We may also recommend preservative-free lubricating drops to keep your eye comfortable and promote healing. In selected cases, we may prescribe topical NSAID drops or cycloplegic drops to reduce pain and light sensitivity. Steroid drops are not routine after foreign body injuries and are used only when prescribed with close follow-up, after infection has been ruled out and epithelial healing status has been assessed. We avoid prescribing topical anesthetic drops for home use, as they can slow healing and mask symptoms of complications. Pain management typically involves oral over-the-counter medications rather than numbing drops.
Recovery and Follow-Up Care
Most foreign body injuries heal quickly once we remove the object and any abrasion begins to repair. You can expect some redness, tearing, and light sensitivity for the first day or two after removal.
Small corneal scratches typically heal within one to three days, while deeper injuries may take up to a week. During this time, your discomfort should gradually decrease each day. Healing progresses faster when you follow our care instructions carefully and avoid activities that might irritate your eye further.
Proper use of your prescribed medications is essential for preventing infection and promoting healing. Before applying any eye drops, always wash your hands with soap and water.
- Tilt your head back and look up at the ceiling
- Gently pull down your lower eyelid to create a small pocket
- Hold the bottle above your eye without touching the tip to your eye or lashes
- Squeeze one drop into the pocket, then close your eye gently for a minute
- If you need multiple types of drops, wait at least five minutes between different medications
Giving your eye time to heal without additional stress or irritation speeds your recovery and reduces the risk of complications. Certain activities can delay healing or introduce infection during the vulnerable recovery period.
Avoid rubbing your eye, even if it feels itchy or irritated, as this can reopen a healing abrasion. Do not wear eye makeup until your eye has fully healed. Skip swimming pools, hot tubs, and other bodies of water that might introduce bacteria. Limit screen time if it increases your discomfort, and avoid dusty or smoky environments that could irritate the healing tissue.
We schedule follow-up visits to ensure your eye is healing properly and to catch any complications early. The timing of these appointments depends on the severity of your injury and the type of foreign body removed.
Certain situations require closer follow-up, often within 24 hours. Contact lens wearers need earlier recheck appointments due to higher infection risk. Injuries involving organic or vegetative matter, central corneal involvement, rust rings, significant abrasions, or concern for retained fragments also warrant faster follow-up. Persistent or worsening symptoms always require prompt reevaluation.
During follow-up exams, we check for signs of infection, measure your healing progress, and adjust your treatment plan if needed. These visits give us the chance to answer any questions you have and confirm that your vision is returning to normal. Even if you feel better, attending your scheduled follow-up is important for protecting your long-term eye health.
While most foreign body injuries heal without problems, complications can occasionally occur. Knowing what warning signs to watch for helps you get prompt treatment if healing does not progress as expected.
- Pain that worsens instead of improving after the first day
- Increasing redness or swelling around your eye
- Discharge that is thick, yellow, or green
- Vision that becomes more blurry or develops new problems
- Worsening light sensitivity with increasing pain, especially if you wear contact lenses
- Increasing foreign body sensation despite treatment
- A new white or cloudy spot appearing on the cornea, which may indicate an ulcer or infection
Frequently Asked Questions
No, you should not wear contact lenses until your eye doctor confirms that your eye has fully healed. Contact lenses can trap bacteria against your cornea and increase your risk of infection while the surface is damaged. They can also irritate the healing tissue and slow down recovery. We will let you know when it is safe to resume wearing your contacts, usually after your cornea has completely healed and all symptoms have resolved.
Rubbing your eye when you feel a foreign body is one of the worst things you can do. Rubbing can push the object deeper into your eye tissue, scratch your cornea, or move a particle across your eye surface and cause multiple abrasions. Instead of rubbing, try blinking several times or flushing your eye with clean water. If gentle flushing does not help, keep your eye closed and visit our office for safe removal.
Most foreign bodies cause only temporary discomfort and heal without affecting your vision long-term. However, certain high-risk foreign bodies can lead to permanent damage if not treated promptly. Metal fragments that penetrate the eye can cause serious internal damage and scarring. Objects that strike the eye at high velocity may damage the retina or other internal structures. Chemical exposures can permanently harm the cornea if not irrigated immediately. Deep or central corneal injuries and infections may also result in scarring that affects vision. Seeking prompt care when a foreign body occurs gives you the best chance for complete recovery without lasting vision problems.
The timeline for feeling normal varies based on what was in your eye and whether it caused a corneal abrasion. If the foreign body was removed without scratching your cornea, you may feel better within a few hours. Small corneal abrasions typically stop hurting within one to two days, though you might notice mild irritation for up to a week. Deeper injuries or embedded foreign bodies may require several days to a week or more before your eye feels completely comfortable again.
Yes, metallic foreign bodies, especially those containing iron, can rust when exposed to the moisture in your eye. This rust can stain the surrounding corneal tissue and cause additional inflammation even after we remove the metal fragment. We use specialized tools to carefully remove any rust ring that forms around a metallic foreign body. Left untreated, a rust ring can lead to persistent discomfort and scarring, which is why prompt removal of metallic objects is so important.
Sometimes a foreign body scratches your cornea and then falls out on its own before your examination. The scratch remains and continues to cause pain even though we cannot find the actual object. Another possibility is that a very small or clear particle evaded detection during the exam. Dry eye, inflammation, or a scratched inner eyelid can also create a foreign body sensation without an actual object being present. We may use fluorescein staining to identify corneal damage or schedule a follow-up exam if symptoms persist.
