Which Eye Drops Help a Corneal Abrasion—and When to Seek Care

Start with the safer relief

Moisturizing eye drops or ointment may soothe a scratched cornea and help keep the eye moist while it heals. This is a general comfort measure, not a way to confirm that you have an abrasion or rule out another injury.

Use moisturizing drops or ointment only when symptoms are mild and no warning sign is present. Avoid rubbing or touching the injured eye. If pain is significant, light causes marked discomfort, your vision changes, or the feeling of a foreign object persists, arrange an eye examination rather than relying on drops alone.

A suspected corneal abrasion needs a different response when the injury involved a sharp object, high-speed debris, or a strong chemical. These circumstances can require prompt or immediate professional care.

For now, take these steps:

• Stop rubbing or touching the injured eye.
• Do not use numbing drops, steroid drops, or an eye patch on your own.
• Avoid contact lenses in the affected eye while it heals.
• Arrange professional evaluation if discomfort is more than mild, symptoms persist, or the injury involved a contact lens or flying material.

Go to emergency care for the warning signs described later in this guide.

Know what can scratch the cornea

A corneal abrasion is a cut or scratch on the clear, front portion of your eye. The injury can happen quickly, before you realize that the surface has been damaged.

Common causes include a fingernail, makeup brush, tree branch, eye rubbing, or dry eyes. Dust or another small object can also hit the cornea or become trapped under an eyelid and scrape the surface.

The surface layer of the cornea is called the epithelium. A corneal abrasion is a defect in that layer, and fluorescein dye can help an eye-care professional find it during an examination. A shallow, uncomplicated abrasion is often called a minor or simple abrasion. Clinicians may also classify an abrasion by its cause. When a foreign body is removed, the remaining scratch is treated like a standard abrasion. A contact-lens-related abrasion follows a different, higher-risk pathway because infection can progress quickly.

A corneal abrasion can follow several everyday situations:

• A fingernail or makeup brush touches the eye.
• A branch or another piece of plant material strikes the eye.
• Dust, sand, wood, metal, or another small particle enters the eye.
• Rubbing the eye damages a surface that is already irritated or dry.
• A foreign body becomes trapped under the upper eyelid and scrapes the cornea with each blink.

A particle trapped under the upper eyelid may create one or more vertical abrasions that worsen when you blink. Do not try to judge the depth of a scratch by how it feels.

Some superficial foreign bodies leave the cornea in the tear film, but others remain on or within it. High-speed debris from drills, saws, grinders, rotary tools, hammering, or explosions can penetrate the eye and may resemble a corneal abrasion. Intraocular penetration can occur after seemingly minor trauma, so an injury involving high-speed material needs emergency assessment.

Protective eyewear can help prevent eye injuries during tasks that could injure the eye. Use sports goggles for contact sports and activities involving high-speed objects. Keeping branches above eye level along walkways and practicing good contact-lens hygiene can also reduce the chance of an abrasion.

Contact lenses change the level of concern. Overwearing lenses, sleeping in them, or having debris trapped beneath them can cause an abrasion. Contact lens-related abrasions have a higher infection risk and need close monitoring, so do not treat them as an ordinary irritated eye.

Stop wearing the affected lens while the eye heals. Do not put it back in until an eye-care professional says it is appropriate. More specifically, keep contact lenses out until the eye is completely healed, usually within two to four weeks. This can be longer than the first few days of symptom improvement. A contact lens-related injury needs professional guidance about antibiotic treatment and follow-up.

Recognize the usual symptoms

A corneal abrasion can cause pain, tearing, sensitivity to light, and a feeling that something is stuck in your eye. You may describe the sensation as a grain of sand that will not come out. Looking toward light may sting.

The usual pattern often follows an event such as dust entering the eye, rubbing, a fingernail, or contact lens wear. Symptoms during healing can include redness, blurred vision, tearing, and light sensitivity. These symptoms are clues, not a diagnosis. Even a small abrasion can be very painful because the cornea has among the highest densities of nerve fibers in the human body.

Healing symptoms should gradually become easier rather than steadily worse. A smaller abrasion often heals within 24 hours, while a larger abrasion may take 2 or 3 days to heal fully. Another clinical reference describes many typical abrasions healing within 24 to 48 hours in people who are in good general health.

A simple abrasion can still be painful while the surface repairs itself. Increasing pain, worsening redness, a persistent foreign-body sensation, or any change in sight should move you from home comfort measures to professional evaluation.

Contact lens wear makes the symptom pattern more urgent because infection can progress quickly after an abrasion. Pain, tearing, and light sensitivity after lens wear deserve prompt eye-care guidance, even if the scratch seems small.

The absence of severe pain does not rule out a problem. A retained particle, infection, or another cause of eye pain may need an examination to identify it. Persistent symptoms after an eye injury should not be managed by repeatedly adding different drops.

Understand how an eye exam finds it

An eye examination checks whether the pain comes from a corneal abrasion or from a more serious problem. The examination should look for a penetrating injury, infection of the cornea, a corneal ulcer, and a foreign body that may still be present.

An eye-care professional can examine the eyelids and the surface of the eye, including under the upper eyelid when a trapped particle is possible. A foreign body can continue to scrape the cornea each time you blink, so finding and removing it matters. After removal, the underlying scratch is treated like a standard abrasion. The exam therefore does two jobs: it finds the surface defect and addresses a source that could keep injuring it.

Many corneal abrasions are not visible to the naked eye. A slit-lamp biomicroscope combines a high-powered light source with a microscope, allowing an eye-care professional to examine the surface closely. During fluorescein staining, the dye spreads across the cornea as you blink and highlights exposed tissue. The clinician may turn the upper eyelid outward when a trapped particle is possible. These steps help distinguish a surface defect from a retained foreign body or another cause of eye pain.

Fluorescein dye helps identify a surface defect. The dye is placed on the eye, spreads across the cornea as you blink, and highlights exposed tissue. The abrasion may look yellow in normal light and green under cobalt blue light.

This test helps the clinician see the location and pattern of the injury. A branching pattern can point toward herpetic keratitis rather than a simple scratch and needs immediate referral. The examination also helps distinguish a surface abrasion from a retained foreign body or another source of eye pain.

Drops may ease discomfort while an untreated cause continues. That is why persistent symptoms, contact lens involvement, high-speed impact, or a chemical injury should lead to professional assessment rather than repeated self-treatment.

During an office examination, an eye-care professional may use an anesthetic drop to make the examination more comfortable. That supervised use is different from taking numbing drops home for repeated pain relief.

Use treatment that matches the injury

Treatment for a corneal abrasion aims to control pain, prevent infection, and help the cornea heal. The appropriate treatment depends on the cause, the size and appearance of the injury, contact lens use, and what the examination finds.

Moisturizing drops or ointment may add a soothing layer and keep the surface moist while it heals. They are comfort measures, not a substitute for an examination when symptoms are significant or the injury has a higher-risk cause. The treatment plan can change when the protective surface layer is absent. Antibiotics, when a clinician prescribes them, are used as protection against infection during that period; the examination still determines whether a foreign body or another problem needs attention.

A clinician may prescribe an antibiotic drop or ointment to help prevent infection. Evidence is lacking for uncomplicated abrasions, although antibiotic treatment is commonly used. The decision belongs to the examining clinician because contact lens injuries, retained foreign bodies, and injuries involving organic material have different concerns. Antibiotic treatment is supported more strongly for complicated abrasions, including contact-lens injuries, retained foreign bodies, or organic-material trauma.

Do not assume that an antibiotic used for another eye problem is appropriate for a new injury. The name of a drop does not show whether it fits the abrasion in front of you.

Oral pain medicine may also be considered in some treatment plans. Guidance on topical nonsteroidal anti-inflammatory eye drops differs: they may relieve pain, but they are not approved for corneal abrasions, and it is uncertain whether they work better than oral pain medicine. Do not choose these drops without guidance from the examining clinician.

Cycloplegic and pupil-widening drops are not recommended for pain from an uncomplicated corneal abrasion. Do not choose these drops based on a general symptom match.

Use this distinction when deciding what to do:

• Moisturizing drops or ointment: May soothe and keep the surface moist while it heals.
• Antibiotic drops or ointment: May be prescribed after an examination to help prevent infection.
• Pain-relieving drops: May be used under clinician direction when appropriate.
• Pupil-widening drops: Are not recommended for pain from an uncomplicated abrasion.
• Numbing or steroid drops: Should not be self-selected for a suspected abrasion.

If the injury involves a contact lens, follow the separate pathway in the next section.

Treat contact-lens injuries differently

A contact lens-related abrasion needs prompt professional treatment and close follow-up. Overwear, sleeping in lenses, or debris trapped beneath a lens can damage the cornea, and infection after an abrasion can progress rapidly to a perforated cornea and permanent vision loss.

Do not choose an antibiotic based on a label or an old prescription. If a contact lens caused the abrasion, an eye-care professional should choose an antibiotic with antipseudomonal activity. Examples named in clinical guidance include a fluoroquinolone or an aminoglycoside, but the choice and use must come from professional direction. Guidance limits these medicines to contact-lens-related abrasions because fluoroquinolone resistance is increasing and aminoglycosides may be toxic to the corneal surface. That is another reason not to reuse an old prescription.

A contact lens-related abrasion needs daily reevaluation until it heals, with a low threshold for referral. This follow-up is different from simply waiting for a mild scratch to feel better.

Do not wear the affected contact lens while the injury heals.

Corneal infiltrates and ulcers require immediate eye-care referral because they can cause permanent corneal damage. New or worsening pain, redness, light sensitivity, blurred vision, or discharge after contact lens wear needs prompt attention.

If a contact lens was involved and you cannot obtain timely eye-care guidance, use emergency care for severe symptoms or any change in sight. Do not wait for repeated drops to solve the problem.

Avoid drops and actions that can cause harm

Numbing eye drops are not for repeated self-treatment of a corneal abrasion. They are intended for one-time use during an eye-care visit, not repeated use throughout the day for pain. Overuse has been associated with corneal damage and permanent vision loss.

Do not use numbing drops to keep working through pain or to decide whether the injury is improving. They can harm the surface, delay healing, and mask symptoms. A drop that briefly removes pain does not show that the abrasion is closing. It can instead make it harder to notice a worsening problem. An eye-care professional may use an anesthetic drop during an examination to make the visit more comfortable, but that supervised use is different from using the drops at home.

Professional guidance about limited anesthetic use for a simple abrasion is not uniform. A clinical reference published on September 3, 2026, reported that the American College of Emergency Physicians recommends topical anesthetics for simple abrasions during the first 24 hours. Another clinical recommendation says topical anesthetics are not recommended, and a review found little or no certainty that they reduce pain during the initial 24 to 72 hours.

That difference is a reason not to self-prescribe numbing drops. If an examining clinician gives you specific instructions, follow those instructions rather than combining advice from different sources.

Avoid these actions while a corneal abrasion is possible:

• Do not use ophthalmic corticosteroids unless an eye-care professional specifically directs you. Steroid drops can promote fungal growth and reactivation of herpes simplex virus.
  Patches do not reduce pain or improve healing time and may increase infection risk, especially after a contact-lens injury or an injury involving soil or vegetation.
• Do not rub or touch the injured eye.
• Do not keep using drops simply because they reduce the sensation for a short time.

A professional reference reported that as many as 25% of patients presenting to an emergency department with ocular complaints had a corneal abrasion. That figure describes emergency-department presentations, not the chance that your symptoms are caused by an abrasion.

Know what healing should look like

A minor, simple abrasion is a shallow surface scratch that typically heals within 24 to 72 hours with standard treatment such as lubricating drops and a topical antibiotic. Another clinical reference says the corneal surface often heals within 24 to 48 hours.

Smaller abrasions may heal within 24 hours or during sleep. Larger abrasions may take 2 or 3 days to heal fully. Tearing, redness, blurred vision, and light sensitivity can occur during this period, but the overall direction should be toward improvement. Do not use the expected healing window to wait through worsening symptoms. A short timeline applies to a simple abrasion, not to a chemical exposure, high-speed impact, contact-lens injury, or other warning sign.

Your eye doctor will usually want to recheck the injury within 24 hours. A recheck can show whether the surface is closing and whether another problem needs treatment.

Keep the follow-up even if the eye feels better when a clinician has asked to see you again. A surface that feels improved may still need evaluation, especially after contact lens wear or an injury involving organic material.

Recurrent corneal erosion can cause the healed surface to lift again because it has not anchored firmly to the layer beneath. The problem often appears when you wake up. Recurrent corneal erosion is the most common reason a previously healed abrasion seems to return weeks or months later. A previous abrasion or basement membrane dystrophy can increase the risk.

A recurrent corneal erosion can last a long time and come and go over several months or years. Repeated morning pain or repeated episodes after an earlier scratch deserve an eye examination rather than repeated short-term self-treatment.

Get emergency help for these warning signs

A strong chemical, a sharp object, or a high-speed impact requires immediate emergency assessment. If a strong chemical such as bleach or oven cleaner enters your eye, keep rinsing with water while getting emergency help and take the container with you.

Get immediate emergency help if a sharp object pierces the eye or something strikes it at high speed, such as during work with power tools or while mowing.

Changes in sight after an eye injury require immediate emergency assessment. Sudden severe eye pain, redness, or a persistent feeling that something is stuck in the eye also warrants immediate emergency ophthalmic care.

Treat these signs as an emergency even if a moisturizing drop briefly changes the discomfort. A drop cannot rule out a penetrating injury, retained foreign body, infection, or another serious cause.

Get immediate emergency help for any of these signs after an eye injury:

• Severe eye pain.
• A headache or strong sensitivity to light.
• Nausea or vomiting.
• Trouble moving the eye or keeping it open.
• Blood or pus coming from the eye.
• Any new change in sight.

Use emergency care for these symptoms rather than waiting for a routine appointment or trying several different eye drops.

Arrange an eye exam when the injury needs evaluation

Arrange prompt eye care when eye pain and watery eyes follow work around flying dust, wood, plants, or metal. An eye-care professional can remove particles and evaluate the damage. This is especially important when the sensation of a foreign body persists or blinking seems to make the pain worse.

Seek immediate ophthalmic care for sudden severe pain, redness, or a persistent foreign-body sensation. An object trapped beneath the upper eyelid can create one or more vertical abrasions that worsen with blinking.

Injuries from a fingernail or tree branch can lead to a fungal infection. This infection is extremely serious and may not appear immediately. Contact an eye-care professional after this type of injury even if the first symptoms seem to settle.

A branching pattern on the cornea can suggest herpetic keratitis and needs immediate referral.

Eye injuries occur across age groups. In one U.S. injury report, the average age of patients with eye injuries was 32 years, and two thirds of injuries occurred in the 19-to-64 age category. The report also found that males made up a higher proportion of injured patients than their share of the U.S. population.

Those figures describe eye injuries in that report, not every corneal abrasion and not your individual risk. A corneal abrasion can happen after ordinary contact with a fingernail, dust, a branch, or a lens, so the cause and warning signs matter more than age or sex when you decide how quickly to seek care.

Use this decision path:

• Mild discomfort with no warning sign: Moisturizing drops or ointment may provide comfort, but arrange an examination if symptoms persist.
• Contact lens involved: Seek prompt eye-care guidance and expect close follow-up until the abrasion heals.
• Dust, metal, wood, plant material, or a trapped particle involved: Arrange professional evaluation so the eye can be checked and the particle removed if needed.
• Chemical exposure, high-speed impact, penetrating injury, sight change, severe pain, or trouble opening the eye: Get immediate emergency help.

When the cause or symptom pattern is unclear, choose an examination instead of adding more drops. If symptoms are not clearly improving within the expected short healing window, contact an eye-care professional. The 24-to-72-hour estimate should never override a warning sign or a higher-risk cause.

Take the next step toward personalized eye care

Moisturizing drops or ointment may soothe a mild suspected abrasion, but numbing drops, steroid drops, patches, and rubbing can create problems when used without direction. Contact lens injuries, persistent symptoms, and injuries from chemicals, sharp objects, high-speed debris, or organic material need a different level of care.

A qualified eye-care professional must decide which treatment fits your individual injury. If you need an eye examination for a possible abrasion or symptoms that continue, Northwest Eye offers eye care in Minnetonka.

How common are corneal abrasions, and who gets them most often?

How long does a corneal abrasion usually take to heal?

A small abrasion often improves within 24 to 48 hours, while a larger one may take two or three days to heal fully. Symptoms should gradually ease during that time. Arrange an eye examination if pain, redness, light sensitivity, blurred vision, or the feeling of something in the eye persists or worsens.

Can I use numbing eye drops for a scratched cornea?

Do not use numbing drops on your own or repeatedly for pain. They may harm the corneal surface, delay healing, or hide signs of worsening injury. Guidance differs about limited use during the first 24 hours for a simple abrasion, so use them only if an examining clinician gives specific instructions.

What should I do if a contact lens caused the abrasion?

Remove the affected contact lens and seek prompt eye-care guidance. Contact lens-related abrasions have a higher infection risk and may require a specific antibiotic and daily reevaluation until healed. Do not wear the lens again during healing, patch the eye, or use leftover medication without professional direction.

When does a scratched eye need emergency care?

Get immediate emergency help after a chemical exposure, sharp-object injury, or high-speed impact. Emergency assessment is also needed for a change in sight, severe pain, sudden redness, trouble opening or moving the eye, nausea or vomiting, headache with light sensitivity, or blood or pus from the eye.

How common are corneal abrasions?

Corneal abrasions are a common eye injury, but the available figure does not estimate population risk. One report found them in as many as 25% of emergency-department visits for eye complaints. Eye injuries occur across age groups, so the injury’s cause, symptoms, and warning signs matter more than age or sex.
