How to relieve pain from a corneal abrasion? 6 quick home remedies

Corneal abrasion, also known as scratched cornea, is a common eye injury that can occur when dust, sand, tree branches, fingernails, or contact lenses damage the eye's surface. According to statistics from ophthalmological organizations, corneal injuries cause millions of people worldwide to seek eye examinations each year. If not treated properly, eye pain due to corneal abrasion can cause severe pain, continuous tearing, light sensitivity, and temporary vision loss.

This article will help you recognize the early signs of a corneal abrasion, understand why you shouldn't self-treat at home, and learn how to safely relieve pain while waiting for an examination. Tiptory also shares important notes to support the recovery process, reduce the risk of complications, and protect long-term vision.

Part 1: When should you see a doctor immediately for a corneal abrasion?

Note 1: Seek medical attention immediately for a corneal abrasion

Don't be complacent if you suspect a corneal abrasion

• Corneal abrasion or scratched cornea is damage to the transparent outer layer of the eye. This eye injury requires early evaluation by an ophthalmologist to determine the extent of the damage and prescribe appropriate treatment.

• Do not self-medicate with eye drops, antibiotics, or pain relievers at home without an accurate diagnosis. Improper treatment can increase the risk of infection, delay wound healing, or affect vision.

Causes of corneal abrasion you might not expect

• In addition to common causes such as sharp objects touching the eye, dust, sand, metal fragments, or foreign objects, corneal abrasion can also occur due to:

  • Wearing contact lenses that are not the correct size or not properly cleaned.

  • Rubbing your eyes too hard, especially when there's a foreign object or itchiness.

  • Eye infections causing damage to the corneal surface.

  • In rare cases, the cornea can become dry or damaged during surgery under general anesthesia if the eyes are not adequately protected.

Signs of eye pain due to corneal abrasion

If you experience any of the following symptoms after an eye impact or foreign object, you should go to a medical facility as soon as possible:

• Eye pain or pain that increases when blinking.

• A gritty sensation, like sand or a foreign object in the eye.

• Red eyes, continuous tearing.

• Eye pain due to corneal abrasion accompanied by blurred vision, especially after eye trauma.

• Light sensitivity, having to squint or difficulty opening eyes in bright light.

• May be accompanied by headache, dizziness, or a slight feeling of faintness due to pain and eye irritation.

See a doctor as soon as possible after an eye injury

• Early examination helps the doctor accurately identify the location and extent of the corneal abrasion, and detect deeper damage or remaining foreign objects in the eye.

• Timely treatment helps relieve pain, promote corneal epithelial healing, reduce the risk of corneal ulcers, infection, and decrease the likelihood of scarring that affects vision.

• If you experience eye pain due to corneal abrasion, severe blurred vision, intense pain, or suspect chemical, metal, or sharp object eye trauma, go to a medical facility or hospital with an ophthalmology department immediately, instead of waiting for symptoms to improve on their own.

Note 2: Use eye drops correctly

Only use eye drops as directed by your doctor

• When you have a corneal abrasion or scratched cornea, not all eye drops available on the market are suitable. Some inappropriate products can slow the healing process, mask symptoms, or increase the risk of complications.

• Therefore, you should only use eye drops recommended by your doctor after the cause and extent of corneal damage have been identified.

Eye drops help support the recovery process

• Depending on the case, the doctor may prescribe eye drops that:

  • Moisturize and lubricate the eye surface, helping to reduce the gritty sensation and eye pain due to corneal abrasion.

  • Reduce the risk of infection with antibiotics if indicated.

  • Control inflammation to support better corneal recovery. Some anti-inflammatory drugs, including corticosteroids, should only be used in appropriate cases and require close monitoring by a specialist.

Do not self-medicate with eye drops for pain relief

• If eye pain due to corneal abrasion makes you uncomfortable, discuss it directly with your doctor for advice on suitable medication. Do not choose eye drops on your own just because they seem to reduce redness or irritation.

• Using the wrong medication can increase the risk of infection, prolong recovery time, or affect vision.

Follow instructions strictly when using

• Only use the correct type of medication, correct dosage, and correct number of drops as prescribed by your doctor.

• Some eye drops may be over-the-counter but should still only be used if recommended by a doctor in cases of corneal abrasion.

• Do not stop medication on your own, switch to another product, or combine multiple types of eye drops without guidance from medical staff. This helps a scratched cornea heal faster and reduces the risk of corneal scarring.

Note 3: Use medication exactly as prescribed

Use antibiotics when prescribed by a doctor

• Not all cases of corneal abrasion or scratched cornea require oral antibiotics. A doctor will only prescribe them if there is a suspected or confirmed risk of infection, especially in contact lens wearers, those with deep wounds, or injuries from contaminated foreign objects.

• Take the medication at the correct dose, for the correct duration, and complete the full course, even if symptoms of eye pain due to corneal abrasion have subsided. Stopping medication too early can lead to incomplete treatment of the infection and increase the risk of antibiotic resistance.

Inform your doctor about all medications you are taking

• Before starting antibiotics, inform your doctor about all medications, supplements, or herbal remedies you are currently using.

• This helps reduce the risk of drug interactions, minimize unwanted side effects, and ensure the most effective treatment for scratched cornea.

Do not self-administer topical anesthetic eye drops at home

• During examination, a doctor may use topical anesthetic eye drops to relieve pain and facilitate corneal examination. However, these medications should only be used in a medical setting under the supervision of qualified personnel.

• Self-administering or overusing topical anesthetic eye drops at home can slow corneal healing, mask worsening symptoms, and increase the risk of ulcers or severe corneal damage.

Pain medication may be needed for severe symptoms

• If eye pain due to corneal abrasion or light sensitivity significantly impacts daily life, the doctor may consider prescribing appropriate oral pain medication.

• Do not self-medicate with pain relievers or other eye treatments without a doctor's guidance, especially if symptoms persist or worsen. Proper treatment from the outset will help corneal abrasion recover faster and reduce the risk of complications affecting vision.

Note 4: Surgery for severe corneal damage

Surgery is only considered in some cases

• Most cases of corneal abrasion or scratched cornea will heal after proper treatment. However, if the damage is too deep, the wound does not heal, recurs frequently, or leaves scars affecting vision, the doctor may consider surgical interventions.

When is surgery needed?

• Your doctor may recommend surgery if you experience one of the following conditions:

  • Eye pain due to corneal abrasion persists despite complete treatment.

  • The cornea is severely damaged or has scarring that reduces vision.

  • The corneal surface does not heal normally or repeatedly suffers recurrent erosions.

  • There are complications affecting the function and structure of the cornea.

The doctor will choose the appropriate treatment method

• Depending on the cause, location, and extent of the damage, the ophthalmologist will advise on the appropriate treatment method. The goal of intervention is to reduce pain, improve vision, promote the recovery process, and limit long-term complications.

Discuss thoroughly before deciding on surgery

• If surgical intervention is needed, the doctor will clearly explain:

  • The reason for surgery.

  • The procedure.

  • Benefits and potential risks.

  • Recovery time and eye care after surgery.

• Adhering to care instructions and follow-up appointments is an important factor in helping the cornea heal well, protecting vision, and reducing the risk of recurrent scratched cornea in the future.

Note 5: Monitor recovery time

The healing time for corneal abrasion depends on the extent of the damage

• Most cases of mild corneal abrasion or scratched cornea will recover within 1-3 days with proper care and treatment.

• For larger scratches or deeper damage, the recovery time may be longer, depending on the extent of the injury, the cause of the trauma, and the individual's health condition.

Deep scratches carry a risk of complications

• If a scratched cornea penetrates deeper layers, the risk of complications will be higher, including:

  • Corneal infection.

  • Formation of corneal scars affecting vision.

  • Persistent pain or frequent recurrence.

  • Vision loss if not treated promptly.

Monitor for abnormal signs during recovery

• During treatment, pay attention to any changes in your eyes. If any of the following signs appear, you should contact your doctor or go to a medical facility immediately:

  • Eye pain due to corneal abrasion becomes increasingly severe or does not improve after a few days.

  • Increased redness, excessive discharge, or tearing.

  • Decreased vision, blurred vision, or new blurry spots.

  • Swelling, severe light sensitivity, or any other abnormal symptoms.

Follow up appointments to protect vision

• Even if symptoms have subsided, you should still follow up with your doctor as scheduled to assess the healing process of the corneal abrasion and detect any complications early.

• Thorough monitoring helps ensure the scratched cornea fully recovers, limits scarring, and reduces the risk of long-term impact on vision.

Part 2: How to quickly relieve corneal abrasion pain at home

Method 1: Temporarily stop wearing contact lenses

Do not wear contact lenses until the cornea recovers

• If you have a corneal abrasion or scratched cornea, stop using contact lenses immediately and switch to glasses during treatment.

• Contact lenses can rub against the damaged corneal area, making the scratch heal slower, increasing discomfort, and worsening eye pain due to corneal abrasion.

• Additionally, continuing to wear contact lenses when the eye is injured increases the risk of corneal infection, especially if the lenses or lens case are not properly cleaned.

Only resume wearing contact lenses with your doctor's approval

• The recovery time for a scratched cornea varies from person to person. For minor injuries, the eye may heal in a few days, but severe cases may require more time.

• Only resume using contact lenses when your doctor confirms that the cornea has fully recovered. Wearing lenses too soon can cause the injury to recur or increase the risk of complications.

Wear sunglasses to reduce light discomfort

• After a corneal abrasion, many people become more sensitive to light. Wearing sunglasses outdoors can help reduce glare, limit irritation, and make the eyes feel more comfortable.

• Choose sunglasses with good UV protection to shield the cornea throughout the recovery process. If light sensitivity persists or worsens, see your doctor for evaluation and treatment adjustment if needed.

Method 2: Do not self-patch your eye

Do not self-patch your eye without medical instruction

• If you have a corneal abrasion or scratched cornea, you should not self-apply an eye patch without your doctor's guidance.

• For most mild corneal abrasions, an eye patch does not help the wound heal faster. On the contrary, covering the eye can reduce the amount of oxygen reaching the cornea, thereby slowing down the recovery process.

Eye patching is only used in some cases

• The doctor may consider using an eye patch when deemed necessary to reduce discomfort or aid the treatment process in some patients.

• The decision to patch the eye will depend on the cause of the corneal abrasion, the extent of the damage, the risk of infection, and the specific condition of each individual.

Eye covering may be needed for extreme light sensitivity

• If eye pain due to corneal abrasion is accompanied by severe light sensitivity, the doctor may recommend using an eye patch or other eye protection measures for a short period to increase comfort.

• However, you should not apply this measure yourself at home as it may not be suitable for your condition.

Prioritize following your doctor's instructions

• Instead of self-patching your eye, adhere to the treatment regimen, use medication as prescribed, and follow up appointments as scheduled.

• If eye pain persists, vision worsens, or any abnormal symptoms appear during the recovery of the corneal abrasion, contact your doctor for evaluation and timely management.

Method 3: Avoid rubbing your eyes when you have a corneal abrasion

Do not rub or scratch your eyes when you have a corneal abrasion.

• When you have a corneal abrasion or scratched cornea, you may feel an itch, a gritty sensation, or as if there's a foreign object in your eye. This is a common reaction during the injury and healing process of the cornea.

• Even if it's very uncomfortable, try not to rub or scratch your eyes. This action can make the scratch deeper, prolong healing time, and worsen eye pain due to a corneal abrasion.

Rubbing eyes increases the risk of infection

• Hands can carry bacteria, dirt, or other pathogens. When you rub your eyes, these agents can easily enter the injured corneal area, increasing the risk of infection and developing complications that affect vision.

• If your eyes feel too itchy or uncomfortable, consult a doctor for guidance on safe symptom relief measures instead of self-treating your eyes.

Keep hands busy to limit the habit of rubbing eyes

• If you often unconsciously bring your hands to your eyes, try engaging in activities that keep your hands busy, such as reading, writing, knitting, drawing, or doing handicrafts.

• Changing this habit helps reduce the number of times you touch your eyes, allowing a corneal abrasion to heal faster.

Supportive measures can be applied during sleep or rest

• Some people have a habit of rubbing their eyes while sleeping or when they are not paying attention. In this case, you might consider wearing soft fabric gloves while resting to limit unconscious touching of your eyes.

• More importantly, always keep your hands clean, trim your fingernails neatly, and follow your doctor's treatment instructions to help a corneal abrasion heal quickly and reduce the risk of complications.

Method 4: Apply cold compress as directed

Only apply cold compress when recommended by a doctor

• When you have a corneal abrasion or scratched cornea, not every case requires a cold compress. You should only use this method if instructed by your doctor, as its effectiveness depends on the extent of the injury and the cause of the eye trauma.

• Improper self-application of a compress can make your eyes more uncomfortable or mask symptoms that need to be monitored.

Cold compress can help reduce swelling and discomfort

• In some cases of mild corneal abrasion, your doctor may recommend a cold compress for the first 24–48 hours after the injury.

• Cold temperatures help constrict blood vessels, reduce swelling, and help soothe eye pain due to a corneal abrasion in the initial stage.

Switch to warm compress when appropriate

• After the initial phase, your doctor may instruct you to switch to a warm compress to support blood circulation around the eye and create favorable conditions for the healing process.

• The timing for switching from a cold to a warm compress will vary for each individual, so always follow your doctor's instructions instead of changing the method yourself.

Apply compress safely

• Do not place ice directly on the eye. Wrap the ice pack or ice in a clean, soft cloth before applying it to the closed eye area.

• Do not apply pressure to the eyeball and stop compressing if you feel increased pain or experience any unusual symptoms.

• If eye pain due to a corneal abrasion does not improve, the eye becomes more red, vision blurs, or swelling worsens, contact your doctor for examination and timely adjustment of the treatment method.

Method 5: Diet to support corneal recovery

Prioritize a nutrient-rich diet to support corneal healing

• When you have a corneal abrasion or scratched cornea, your body needs many nutrients to regenerate tissue and repair damage. A balanced diet with plenty of green vegetables, fresh fruits, whole grains, and protein-rich foods will contribute to supporting the recovery process.

• In addition to taking medication as prescribed, a scientific diet also helps boost immunity and reduce the risk of infection during treatment.

Supplement vitamin C to support collagen production

• Vitamin C participates in the synthesis of collagen – an important component that helps repair damaged tissues, including the cornea.

• Sources of vitamin C-rich foods include:

  • Bell peppers.

  • Broccoli.

  • Cauliflower.

  • Oranges, tangerines, grapefruits.

  • Guava.

  • Strawberries.

  • Cantaloupe.

  • Lychee.

• Most adults can meet their vitamin C needs through a varied diet without needing supplements.

Vitamin E helps protect corneal cells

• Vitamin E is an antioxidant that helps protect cells from damage by free radicals, thereby supporting the recovery process of a corneal abrasion.

• You can supplement vitamin E from foods such as:

  • Almonds.

  • Sunflower seeds.

  • Wheat germ.

  • Spinach.

  • Avocado.

  • Peanut butter.

  • Mango.

  • Hazelnuts.

B vitamins contribute to tissue repair

• B vitamins are involved in many metabolic processes in the body and help maintain the health of the nervous system and eye tissues.

• Foods rich in B vitamins include:

  • Salmon.

  • Tuna.

  • Cod.

  • Halibut.

  • Skinless turkey.

  • Bananas.

  • Potatoes.

  • Lentils.

  • Soy milk.

  • Cheese.

Lutein and zeaxanthin help protect eyes

• Lutein and zeaxanthin are two carotenoids with antioxidant roles, helping to protect the retina and lens from the effects of strong light and UV rays.

• Although they do not directly treat eye pain due to a corneal abrasion, adequate supplementation of these two nutrients still contributes to maintaining eye health during recovery.

• Foods rich in lutein and zeaxanthin include:

  • Spinach.

  • Kale.

  • Collard greens.

  • Broccoli.

  • Peas.

  • Corn.

  • Egg yolks.

Do not self-medicate with supplements

• If you want to use vitamins or supplements, consult your doctor or a nutritionist first, especially if you have chronic diseases or are taking other medications.

• In most cases, a varied, balanced diet rich in natural foods can provide enough essential nutrients to support corneal abrasion recovery and protect long-term eye health.

Method 6: Rest to help eyes recover quickly

Take time to rest so the body can focus on healing

• When you have a corneal abrasion or scratched cornea, the body mobilizes energy to repair damaged tissues. Adequate rest helps the corneal epithelial regeneration process to occur more effectively, while also reducing eye pain due to a corneal abrasion.

• Getting enough sleep and avoiding staying up late also contributes to boosting immunity, helping the eyes recover faster.

Reduce activities that make the eyes work hard

• In the first few days after the injury, limit:

  • Reading books or documents for long periods.

  • Using phones, computers, and screens for too long.

  • Watching TV continuously or working in environments with bright light.

• Giving your eyes regular breaks helps reduce dry eyes, irritation, and discomfort when blinking.

If possible, temporarily reduce study or work load

• If eye pain due to a corneal abrasion affects your vision or makes it difficult to concentrate, consider taking time off from school or reducing your workload for a short period as advised by your doctor.

• This helps reduce eye strain and creates favorable conditions for the corneal abrasion to heal without additional pressure from prolonged visual activities.

Create a comfortable resting environment for your eyes

• Rest in a clean, cool place and avoid overly bright light.

• If you feel uncomfortable when exposed to light, wear sunglasses when outside or dim the lights in the room.

• Combining appropriate rest with proper medication and scheduled follow-up appointments will help the corneal abrasion heal faster, reduce the risk of complications, and quickly restore normal vision.

Part 3: What not to do for a corneal abrasion to avoid blindness?

Note 1: Do not self-administer eye ointments

Do not self-administer eye ointments or anesthetics at home

• When treating a corneal abrasion or scratched cornea, doctors may use certain eye ointments or anesthetics during examination and treatment. These medications are only safe when used in correct dosages and under the supervision of medical professionals.

• You should not buy or use eye ointments, anesthetics, or eye treatment medications at home without a doctor's prescription.

Misuse of medication can worsen the condition

• Self-medicating, especially with eye drops or ointments that have an anesthetic effect, can mask symptoms, preventing you from realizing that the injury is progressing.

• Furthermore, improper use can slow down the healing process of a corneal abrasion, increase the risk of infection, corneal ulcers, and affect vision.

Only use medication prescribed or recommended by a doctor

• During the treatment of eye pain due to a corneal abrasion, only use medications that have been prescribed or instructed by your doctor.

• Depending on the level of pain and the extent of the injury, your doctor may prescribe oral pain relievers to help you feel more comfortable while the cornea heals.

Do not alter the treatment plan yourself

• Do not change medication, increase or decrease dosage, or stop medication without consulting your doctor.

• If eye pain due to a corneal abrasion does not subside, if eye redness increases, vision blurs, or any unusual symptoms appear, seek re-examination promptly for assessment and adjustment of the appropriate treatment method.

Note 2: Do not try to remove foreign objects from your eye yourself

Do not try to remove foreign objects from your eye yourself

• A corneal abrasion or scratched cornea often occurs when dust, sand, metal fragments, tree branches, or other foreign objects rub against the corneal surface. If a foreign object remains in the eye, you may feel grittiness, pain, and continuous tearing.

• Even if it's very uncomfortable, you should not try to remove the foreign object from your eye with your hands, tweezers, cotton swabs, or any other tool.

Self-removal of foreign objects can lead to more serious injury

• Attempting to remove a foreign object at home can:

  • Make the corneal abrasion deeper.

  • Increase the risk of eye infection.

  • Push the foreign object deeper into the eye.

  • Damage important eye structures, affecting vision.

Seek medical attention for safe removal

• If you suspect a foreign object is in your eye, go to a hospital or eye clinic as soon as possible.

• A doctor will use specialized instruments to locate the foreign object, remove it safely, and examine the extent of the corneal abrasion before prescribing the appropriate treatment.

While waiting for examination, protect your eyes properly

• Do not rub your eyes or blink too hard as this can cause the foreign object to rub more strongly against the cornea.

• Do not self-administer any drops or try to rinse your eyes multiple times if the foreign object is likely to be embedded or is sharp.

• If eye pain due to a corneal abrasion increases, vision blurs, there is excessive tearing, or you cannot open your eye, go to a medical facility immediately for timely treatment to reduce the risk of complications and protect your vision.

Note 3: How to prevent recurrent corneal abrasions

Protect your eyes to avoid repeated corneal abrasions

• Repeated corneal abrasions or scratched corneas can increase the risk of scarring, affecting vision, and in severe cases, may require surgical intervention.

• After your eye has recovered, actively protect your eyes to reduce the risk of recurrence and maintain long-term visual health.

Wear protective eyewear when there is a risk of eye injury

• Use protective glasses or standard sunglasses when:

  • Working with machinery, metal, wood, or chemicals.

  • Mowing the lawn, drilling, grinding, or doing home repairs.

  • Participating in sports or climbing.

  • Moving in dusty, sandy, or windy environments.

• Protective eyewear helps prevent foreign objects from entering the eyes – one of the common causes of corneal abrasions.

Use contact lenses correctly

• If wearing contact lenses, make sure to:

  • Wash your hands thoroughly before inserting or removing lenses.

  • Clean and store lenses according to instructions.

  • Change lens solution daily.

  • Do not wear lenses beyond the recommended time or while sleeping if the lenses are not designed for overnight wear.

• Using contact lenses correctly helps reduce the risk of corneal abrasions, infections, and other eye complications.

Do not rub your eyes when there is dust or a foreign object

• If dust or sand gets into your eye, do not rub your eye as this can cause the foreign object to rub more forcefully against the cornea and result in eye pain due to a corneal abrasion.

Seek medical attention if you cannot remove the foreign object

• If the foreign object remains after rinsing, or if your eye continues to be painful, red, watery, blurry, or feels gritty for an extended period, visit a medical facility or an ophthalmologist.

• Do not attempt to remove the foreign object yourself with tweezers, cotton swabs, or hard objects, as this can severely scratch the cornea and increase the risk of infection.

Maintain daily eye care habits

• Have regular eye exams, especially if you frequently wear contact lenses or work in environments with a risk of eye injury.

• Keep your hands clean and avoid touching your eyes.

• Proactively protecting your eyes in daily life will help reduce the risk of corneal abrasion, limit eye pain due to corneal scratches, and preserve your vision long-term.

Important notes for eye care

See a doctor immediately if unusual symptoms appear

• During treatment for corneal abrasion or scratched cornea, contact your doctor or visit a medical facility immediately if you experience symptoms such as:

  • Fever.

  • Nausea or vomiting.

  • Decreased vision or increased blurriness.

  • Worsening eye pain or any other unusual symptoms.

• These signs may indicate an infection or complication that requires timely treatment to protect your vision.

Do not reuse old eye drops

• Do not reuse antibiotic eye drops or leftover prescription medication from previous treatments, even if current symptoms seem similar.

• Also, do not share eye drops with others.

• The tip of the bottle may have become contaminated with bacteria after opening. Continuing to use it can introduce bacteria into the eye and worsen a scratched cornea or cause a new infection.

• After completing treatment, discard any leftover prescription eye drops as directed by your pharmacist or healthcare provider.

Do not apply food to your eyes

• Do not use cucumbers, potatoes, or frozen foods to apply to your eyes if you have a corneal abrasion.

• As food thaws, bacteria can grow and come into direct contact with the damaged corneal area, increasing the risk of infection and prolonging recovery time.

Use only clean and sterile materials

• If your doctor recommends cold compresses to reduce swelling or alleviate eye pain from a scratched cornea, use a clean compress or sterile cloth wrapped around ice as directed.

• Do not place ice directly on your eyes and always ensure that items coming into contact with your eyes are clean to reduce the risk of infection.

Adhere to treatment instructions to protect vision

• Following your doctor's instructions, attending follow-up appointments, and avoiding unverified care methods will help a corneal abrasion heal safely.

• If symptoms do not improve after a few days or worsen, seek medical attention immediately instead of self-treating at home. Early treatment is the most effective way to reduce the risk of complications and protect long-term vision.
