What To Do If You Scratch Your Eye?

If you scratch your eye, the first step is to rinse it gently with clean water or sterile saline solution. Do not rub the eye, do not touch it with anything, and do not try to remove any object that might be stuck in it. If the scratch is painful, you cannot keep your eye open, your vision changes, or you suspect something sharp or chemical caused the injury, go to an eye doctor or emergency room right away.

What Is a Scratched Eye?

A scratched eye is an injury to the cornea, the clear dome-shaped surface that covers the front of your eye. In medical terms, this is called a corneal abrasion. The cornea is packed with nerve endings, which is why even a tiny scratch can cause intense pain, burning, and the feeling that something is still in your eye.

Scratches can happen in many ways. A fingernail, a tree branch, makeup brush, dust, sand, or a piece of metal can all cause one. Even something as simple as sleeping in contact lenses or having a torn contact lens in your eye can scrape the cornea.

Most corneal abrasions are minor and heal on their own within a few days. But some are serious. A deep scratch, a scratch that becomes infected, or one that damages the deeper layers of the cornea can lead to permanent vision problems if not treated properly.

What To Do If You Scratch Your Eye?

The most important rule is to avoid making it worse. Do not rub your eye, no matter how much it itches or waters. Rubbing can turn a shallow scratch into a deeper one and push debris further into the tissue.

Here is what to do right after the injury:

• Rinse gently. Use clean water or sterile saline solution to flush the eye. Lean over a sink or use a clean cup or eyecup. Do not use tap water directly from the faucet with high pressure.
• Blink several times. Blinking can help move tears across the surface and may wash away small particles.
• Pull the upper eyelid over the lower eyelid. This old trick can help tears flush out loose debris, but only if something is clearly moving around on the surface.
• Wear sunglasses. Bright light can make the pain worse. Keeping the eye shaded helps.
• Do not patch the eye. Older advice said to patch the eye shut. Current medical guidance generally advises against tight patching because it can slow healing and increase the risk of infection.

If something is embedded in the eye — like a piece of glass, metal, or a splinter — do not touch it and do not try to remove it. Cover the eye loosely with a clean cloth or paper cup and get emergency medical care.

When To See a Doctor Immediately

Some eye scratches need professional care. You should see a doctor or go to urgent care if you experience any of the following:

• Vision changes, including blurriness, double vision, or loss of vision
• Severe pain that does not improve with rinsing
• The feeling that something is still in your eye after rinsing
• Light sensitivity that is intense or worsening
• Redness that spreads or increases over hours
• Discharge from the eye, which may indicate infection
• A known chemical injury or exposure to a foreign object at high speed, such as from grinding or sawing metal
• A scratch caused by a contact lens

Contact lens wearers need special attention. A scratched cornea combined with contact lens use carries a higher risk of bacterial infection. If you scratch your eye while wearing contacts, remove the lens if it is not stuck, and do not put it back in. See a doctor promptly.

Do not wait overnight if you have any of these symptoms. Corneal infections can progress quickly, and early treatment is the best way to protect your vision.

What a Doctor Will Do

At a clinic or emergency room, a doctor will examine your eye. They may use a special yellow dye called fluorescein and a blue light to see the scratch clearly. This test is painless and helps the doctor judge the depth and size of the abrasion.

Depending on the injury, treatment may include:

• Antibiotic eye drops or ointment to prevent infection
• Pain relief — often over-the-counter medication, though prescription drops may be used for severe pain
• Follow-up appointment to check that the cornea is healing properly

Doctors rarely patch the eye anymore. Studies have shown that patching does not speed up healing and may increase the risk of infection. The current standard of care is to keep the eye open and use medicated drops.

If the scratch is deep, if it does not heal within a few days, or if there are signs of infection, the doctor may refer you to an ophthalmologist — a medical doctor who specializes in eye care.

How Long Does a Scratched Eye Take To Heal?

Most minor corneal abrasions heal within 24 to 72 hours. The surface layer of the cornea regenerates quickly. Pain usually improves significantly within the first day or two.

Deeper scratches take longer. If the injury extends into the stroma, the thicker middle layer of the cornea, healing can take a week or more. In some cases, the cornea may form scar tissue, which can affect vision permanently.

You may notice that your eye feels better one day, then hurts again the next. This is common. The new surface layer is fragile and can tear again easily. Avoid rubbing the eye for at least a week after the injury, even if it feels fine.

What Not To Do After Scratching Your Eye

Some common instincts can cause more harm. Avoid these actions:

• Do not rub. Even light rubbing can reopen a healing scratch.
• Do not use tweezers or cotton swabs to remove anything from your eye.
• Do not rinse with hydrogen peroxide, alcohol, or any cleaning solution. These will damage the cornea further.
• Do not use redness-relief eye drops. These contain vasoconstrictors that reduce redness but do not treat abrasions and can mask important signs of infection.
• Do not wear contact lenses until a doctor confirms the eye has healed completely.
• Do not use eye drops that are not preservative-free unless prescribed by a doctor.

Can a Scratched Eye Heal on Its Own?

Yes, many minor scratches heal without any treatment. If the scratch is superficial, caused by something like a fingernail or dust, and you have no vision changes or severe pain, the cornea can repair itself within a couple of days.

That said, you cannot always tell how deep a scratch is by how it feels. The cornea’s nerve endings are so sensitive that a tiny surface scratch can feel identical to a deep one. If you are unsure, it is reasonable to see a doctor. An eye exam takes minutes and can prevent a small problem from becoming a serious one.

Signs that healing is happening include reduced pain, less watering, and improved comfort over 24 to 48 hours. If none of these occur, or if symptoms worsen, seek medical care.

How To Prevent Eye Scratches

Most eye scratches are accidents, but many are preventable. Simple precautions reduce your risk:

• Wear safety glasses when mowing, using power tools, hammering, or working with chemicals.
• Trim fingernails of young children who play near your face.
• Handle contact lenses carefully. Follow cleaning instructions, replace them on schedule, and never sleep in lenses not designed for overnight wear.
• Be careful with makeup applicators near the eye, especially mascara wands.
• Wear protective eyewear for sports like racquetball or squash, where fast-moving balls are common.

If you work in an environment with dust, metal shavings, or chemicals, eye protection is not optional. It is the single most effective way to prevent corneal abrasions.

When Is Eye Pain a Medical Emergency?

Eye pain alone is not always an emergency, but certain combinations of symptoms require immediate care. Sudden vision loss, severe pain with nausea or vomiting, or pain that follows chemical exposure are all emergencies. So is pain accompanied by a dilated pupil that does not respond to light, or a visible change in the shape or color of the eye.

If you are unsure whether your injury is serious, call a doctor. Most eye care practices have after-hours lines. Describe exactly what happened and how the eye feels. They will tell you whether to come in or go to the emergency room.

Do not let embarrassment or uncertainty delay care. Eye injuries are common, and doctors see them every day. Getting a scratch examined early is the best way to protect your long-term vision.
