TL;DR
A corneal abrasion is a scratch on the clear surface of the eye. It causes eye pain, watery eyes, blurred vision, and light sensitivity. Most small scratches heal within 24 to 48 hours with flushing, antibiotic drops, and no eye rubbing. Larger scratches can lead to infection, ulcers, or scarring, so follow-up with an eye care provider matters.
Quick Answer
A corneal abrasion is a scratch on the surface of the cornea, the clear covering of the eye, often caused by dust, fingernails or contact lenses. Symptoms include pain, a feeling something is in the eye and light sensitivity. Flush the eye, never rub it, and see an eye care provider. Most people feel better within 24 to 48 hours. [1]
What the research says
Patching may not speed healing. A Cochrane review of 12 trials (1,080 participants) found patched and unpatched simple abrasions were about equally healed by 48 hours (risk ratio 0.97, 95% CI 0.91 to 1.02) and 72 hours, and patching did not clearly reduce pain (Lim et al., Cochrane Database of Systematic Reviews, 2016) [2].
The benefit of antibiotic drops is still unclear. A Cochrane review of 2 trials (527 participants) rated the evidence low to very low certainty; in one trial of 374 people, essentially all had healed without complication by day 3, so any added benefit of antibiotics could not be shown (Algarni et al., Cochrane Database of Systematic Reviews, 2022) [3]. Providers still commonly prescribe them to guard against infection.
Most scratches heal fast, and topical NSAID drops mainly cut the need for pain pills. A Cochrane review of 9 trials (637 participants) found topical NSAIDs reduced the need for rescue oral pain medicine at 24 hours (RR 0.46, 95% CI 0.34 to 0.61, low-certainty evidence); in the one trial that tracked healing, 9 in 10 control abrasions had healed by 24 hours and all by 48 hours (Wakai et al., Cochrane Database of Systematic Reviews, 2017) [4].
What Is a Corneal Abrasion?
A corneal abrasion is a scratch on, or an injury to, the surface of your cornea, the clear covering on your eye. The surface layer of the cornea is called the epithelium, and the cornea has five layers in total. You may also hear this injury called a scratched eye or a scratched cornea. [1]
A corneal abrasion is not likely to be a serious injury. However, you should still make an appointment with your healthcare provider. If the scratch develops into an infection, it could cause more damage. [1]
The cells in the cornea's surface layer reproduce very quickly, which is why small scratches tend to heal fast. But timing and protection matter: the first steps you take in the minutes after the injury shape your recovery.
Key Facts at a Glance
Fact | Detail |
What it is | A scratch on the surface (epithelium) of the cornea |
Also called | Scratched eye, scratched cornea |
Cornea layers | Five, with the epithelium on top |
Usual severity | Not likely serious, but needs follow-up |
Main risk if ignored | Infection that causes further damage |
Typical recovery | 24 to 48 hours for minor scratches |
Where the Cornea Sits in Your Eye
The cornea is the transparent front window of the eye. Light passes through it before reaching the iris and lens. Because the epithelium is exposed to the outside world, it is the layer that objects like dust, sand, and fingernails can scratch during daily life.
What Does a Corneal Abrasion Feel Like?
A scratched cornea has a distinctive set of symptoms. The hallmark is eye pain combined with the persistent feeling that something is stuck in your eye, even when the particle is already gone. The signs and symptoms can include: [1]
Symptom | What You May Notice |
Eye pain | Soreness ranging from mild irritation to sharp pain |
Foreign-body sensation | Feeling that something is in your eye |
Watery eyes | Excess tearing as the eye tries to flush itself |
Blurred vision | Sight that seems fuzzy or unclear |
Red eyes | Visible redness around the scratch |
Light sensitivity | Discomfort in bright light (photophobia) |
Swelling | Swollen eyes or eyelids |
These symptoms usually appear right after the injury. The foreign-body sensation is worth paying attention to: if it does not fade after flushing and blinking, a scratch may be present.
The seven common symptoms of a corneal abrasion.
What Causes a Corneal Abrasion?
The most common cause is getting something in your eye while working with equipment or tools. Particles that can scratch the cornea include dust, dirt, sand, pieces of plants, tiny bits of wood or metal, make-up brushes or applicators, and even your own fingernails. [1]
Contact lenses are another major cause. A corneal abrasion can develop from your contact lenses if you: [1]
Contact Lens Habit | How It Causes a Scratch |
Wearing lenses when eyes are dry | The lens drags across a dry corneal surface |
Lenses that don't fit well | A poorly fitting lens rubs the epithelium |
Too much force inserting or removing | Mechanical force scrapes the surface layer |
Risk Factors
Certain activities and conditions raise your risk of scratching the cornea: [1]
Risk Factor | Example Situation |
Working around eye hazards | Grinding machines, sawmills |
Yard work without protection | Landscaping without safety glasses |
Injury-prone sports | Sports that may cause eye injuries |
Contact lens use | Daily wear without careful hygiene |
Dry eyes | Dry surface makes scratching easier |
Eye rubbing | Repeated or forceful rubbing |
Possible Complications
Small corneal abrasions are mostly minor and heal quickly. Larger scratches are more likely to cause complications, which is why professional follow-up matters. [1]
Complication | Description |
Keratitis | Inflammation of the cornea |
Corneal ulcers | Open sores on the corneal surface |
Iritis | Inflammation of the iris, the colored circle around your pupil |
Recurrent erosion syndrome | Repeated episodes of eye pain and blurred vision because the cornea's top layer keeps breaking down; also called recurrent corneal erosion syndrome |
If an unhealed scratch develops into an infection or scarring, both of these could eventually cause loss of vision. This is the main reason a scratch that seems minor still deserves a provider's evaluation. [1]
How Is a Corneal Abrasion Diagnosed?
Your healthcare provider will start by asking about your medical history and symptoms, including what you were doing around the time your eye started to bother you. [1]
A complete eye exam is performed, including a slit lamp exam, a microscope that lets the provider see into your eyes. If the provider suspects something is trapped under your eyelids, they may flip your eyelids inside out to check. The provider may also instill a yellow dye called fluorescein into your eye. The dye fills in any breaks in the skin of the eye and helps find abrasions easily. [1]
Diagnostic Step | Purpose |
Medical history and symptom questions | Identifies how and when the injury happened |
Complete eye exam | Checks overall eye health after the injury |
Slit lamp exam | Microscope view of the corneal surface |
Eyelid inspection | Looks for trapped particles under eyelids |
Fluorescein dye test | Highlights breaks in the corneal skin |
How a corneal abrasion is diagnosed, step by step.
How Is a Corneal Abrasion Treated?
Treatment starts immediately with first aid and continues with prescription care from your provider. The single most important rule: never rub your eye. [1]
First Steps and Particle Removal
You or your provider may start by flushing the eye with clean water or saline solution. If something remains in the eye, your provider may use a swab or instrument to remove the particle, using topical anesthesia (numbing ointment or drops) so it does not hurt. [1]
Medications
Your provider will prescribe medication to prevent infection, typically antibiotic eye drops or ointment. You will be told how long to use them; you can usually stop once you go an entire day without symptoms. If you are not better after three days, tell your provider. [1]
Treatment Type | Common Options |
Topical antibiotics | Erythromycin ointment; ciprofloxacin drops; moxifloxacin drops |
Oral pain relief | Over-the-counter NSAIDs for small scratches that still hurt |
Topical analgesic | Prescription pain-relieving eye drops or ointment |
You probably will not need pain relievers for a very small scratch. If you do, your provider will probably recommend an over-the-counter oral NSAID (nonsteroidal anti-inflammatory drug). In other cases, a topical analgesic may be prescribed. [1]
Bandage Contact Lens
Quite often, providers use a bandage contact lens to allow the abrasion to heal and to reduce pain associated with blinking. In cases where the risk with contact lenses is high, providers may recommend a pressure patch with gauze and tape instead. There is a risk of infection with a bandage contact lens. If you have one, you will need to follow up within one to two days for monitoring. [1]
Treatment flow and recovery timeline: minor scratches feel better in 24 to 48 hours; call your provider if not better after 24 hours or 3 days.
How Long Does Recovery Take?
If the corneal abrasion is minor, most people feel better in 24 to 48 hours. The cells in that part of the eye reproduce very quickly. Larger scrapes may take longer to heal. If your eye is not feeling better after 24 hours, contact your optometrist or ophthalmologist. [1]
Recovery Stage | Timeline |
First aid (flushing) | Immediately after injury |
Most feel better (minor scratch) | 24 to 48 hours |
Larger scrapes | Longer than 48 hours |
Call provider if not improving | After 24 hours |
Antibiotic stop point | After a full symptom-free day |
Not better after | 3 days of treatment |
What Is the Outlook?
Most corneal abrasions heal within a few days and cause no further problems. If you need and get treatment, your vision should be fine. The important caution applies to scratches that do not respond to care: eye scratches that do not heal or do not respond to treatment could lead to infections or scarring, and both of these things could cause loss of vision. [1]
Scenario | Expected Outcome |
Minor scratch with prompt care | Heals in a few days, no lasting effects |
Minor scratch, treated | Vision should be fine |
Unhealed or treatment-resistant scratch | Risk of infection or scarring |
Scarring or infection develops | Possible vision loss |
Can a Corneal Abrasion Be Prevented?
You can reduce your risk by using protective eyewear and practicing good hygiene with your contact lenses. [1]
When to Use Eye Protection
Situation | Eye Protection Needed |
Working with chemicals | Yes: goggles |
Yard work (mowing, cutting bushes) | Yes: safety glasses |
Contact sports (baseball, hockey) | Yes: sport eye protection |
Machinery (grinders, drills, sanders, welding) | Yes: safety glasses or goggles |
Repair work (carpentry, painting) | Yes: safety glasses |
Contact Lens Risk Reduction
Habit | Recommendation |
Lens hygiene | Clean and disinfect your lenses |
Wear time | Don't wear lenses longer than recommended |
Dry eyes | Don't wear lenses when eyes are very dry; ask about lubricating drops |
Inserting and removing | Avoid being too rough during difficult insertion or removal |
How Do You Take Care of Yourself?
When the scratch happens, flush your eye with clean water or sterile saline. Do not rub your eye. You can try blinking for a bit or keeping your eye completely closed. One useful trick: pulling your top eyelid over your bottom eyelid makes your eye water, and the tears can help a piece of dust or other particle come out of your eye. [1]
When Should You See an Eye Care Provider?
If you think something is in your eye and flushing or blinking does not remove it, see your eye care provider for further evaluation. This is especially true if you are in a lot of pain or cannot see well. An optometrist or ophthalmologist should handle removing particles from your eye. If you have followed your treatment recommendations but your eye is not better after 24 hours, call your provider. Call an eye care provider before going to the emergency room during normal business hours. [1]
When to Seek Urgent or Emergency Care
You may need urgent care or an emergency room visit if you cannot reach an eye care provider, or if it is outside normal business hours, in these cases: [1]
Emergency Sign | Why It Matters |
Something has pierced your eye | Deep injury beyond a surface scratch |
Extreme pain | Sign of serious damage or infection |
Cannot see well, or sudden vision decrease | Possible threat to vision |
Fluid coming out of your eye | Sign of a penetrating injury |
Questions to Ask Your Healthcare Provider
Question | Why It Matters |
What should I watch out for as I heal? | Keeps you alert to complications |
Are there side effects or complications from this treatment? | Informs safe use of drops and bandage lenses |
Do I need a follow-up appointment? | Ensures the scratch heals fully |
Conclusion
A corneal abrasion is a scratch on the clear surface of your eye, most often caused by dust, debris, or rough contact lens handling. While usually minor, it causes real pain and deserves professional care: an untreated scratch can develop into infection, ulcers, or scarring that threatens your vision. Flush the eye with water or saline right away, never rub it, and see an eye care provider for an exam, possible antibiotic drops, and a recovery plan. Most people feel better within 24 to 48 hours.
Frequently Asked Questions
What is a corneal abrasion in simple terms?
A corneal abrasion is a scratch on the surface of your cornea, the clear covering of your eye. The top layer, called the epithelium, is the part that gets scratched. It is also called a scratched eye or scratched cornea.
What does a scratched cornea feel like?
Typical symptoms include eye pain, the feeling that something is in your eye, watery eyes, blurred vision, red eyes, light sensitivity (photophobia), and swollen eyes or eyelids.
What causes a corneal abrasion?
Common causes include dust, dirt, sand, plant pieces, tiny bits of wood or metal, make-up brushes, and fingernails. Contact lenses worn when eyes are dry, ill-fitting lenses, or rough insertion and removal can also scratch the cornea.
Who is at risk of scratching their cornea?
Risk factors include working around grinding machines or sawmills, landscaping without safety glasses, injury-prone sports, wearing contact lenses, having dry eyes, and rubbing your eyes repeatedly or with too much force.
Can a corneal abrasion cause serious complications?
Yes. Larger scratches can lead to keratitis, corneal ulcers, iritis (iris inflammation), or recurrent erosion syndrome, with repeated pain and blurred vision. Unhealed scratches that become infected or scarred can cause vision loss.
How is a corneal abrasion diagnosed?
Providers take your history, perform a complete eye exam with a slit lamp microscope, may flip the eyelids to check for trapped particles, and may use fluorescein dye, which fills in breaks in the eye's surface so the abrasion is easy to see.
How is a corneal abrasion treated?
First, flush the eye with water or saline and never rub it. A provider removes trapped particles with numbing drops, prescribes antibiotic drops or ointment (such as erythromycin, ciprofloxacin, or moxifloxacin), and often places a bandage contact lens or pressure patch to reduce blinking pain.
How long does a corneal abrasion take to heal?
Most people with a minor abrasion feel better in 24 to 48 hours because corneal surface cells reproduce quickly. Larger scrapes take longer. Contact your provider if your eye is not better after 24 hours, or if you are not improved after three days of treatment.
Can I wear a bandage contact lens to heal a scratch?
Quite often providers use a bandage contact lens to help the abrasion heal and reduce blinking pain. There is an infection risk, so follow-up within one to two days is required. Where contact lens risk is high, a gauze and tape pressure patch is used instead.
How do I prevent a corneal abrasion?
Wear eye protection when working with chemicals, doing yard work, playing ball or puck sports, using grinders, drills, sanders, or welding equipment, or doing carpentry and painting. Clean and disinfect contact lenses, don't overwear them, and avoid wearing them when your eyes are very dry.
When should I go to the emergency room for an eye injury?
Seek urgent or emergency care if you cannot reach an eye care provider and something has pierced your eye, you are in extreme pain, you cannot see well or vision suddenly decreases, or fluid is coming out of your eye.
