A scratched eye, known medically as a corneal abrasion, feels like something is stuck in your eye that you cannot get out. Most people describe it as a sharp, intense pain that gets worse with blinking or moving the eye. You may also experience significant tearing, redness, and a sudden sensitivity to light that makes you want to keep the eye closed.
What Does A Scratched Eye Feel Like Compared to Other Eye Problems?
The sensation of a scratched eye is distinct from other common eye issues. With pink eye or conjunctivitis, you usually feel a gritty or sandy sensation that is more of a constant irritation. A scratched eye, however, produces a sharper, more localized pain that often feels like a needle or a piece of glass is pressing into the surface.
This is because the cornea, the clear front surface of your eye, has more nerve endings than almost any other part of your body. When those nerves are exposed by a scratch, every blink drags your eyelid across the raw area. That creates a specific stabbing or burning feeling that is hard to ignore. People often say they cannot keep the eye open without intense discomfort.
Another key difference is the eye’s reaction. A scratched eye will often produce a flood of tears as the body tries to wash out the irritant and protect the area. You may also notice your vision becomes blurry or hazy in that eye. This is not the same as the general discharge or crusting you see with an infection.
What Are the Most Common Causes of a Scratched Eye?
Most corneal abrasions happen from everyday accidents. The most common cause is getting poked in the eye by a fingernail, a tree branch, or a baby’s hand. Another frequent cause is a piece of dust, sand, or metal that gets trapped under your eyelid and scratches the surface as you blink.
Contact lens wearers are at a much higher risk. A tiny piece of grit under a lens can scrape the cornea with every blink. Sleeping in contacts or using old solution can also weaken the cornea’s surface, making it easier to scratch. The CDC reports that contact lens-related corneal infections send thousands of people to emergency rooms each year.
Less common causes include getting hit in the eye with a sports ball or rubbing your eyes too hard when they are already dry. Even a piece of paper sliding across your eye can cause a scratch. The cornea is very delicate, and it does not take much force to damage it.
How Long Does the Pain of a Scratched Eye Last?
The intense pain from a corneal abrasion typically lasts for the first 12 to 24 hours. The cornea heals very quickly because it has a rich supply of nerves and blood vessels at its edges. Most minor scratches heal within one to three days. You should notice the sharp pain fading significantly after the first night of sleep.
However, the pain can return suddenly. A well-known phenomenon called “recurrent corneal erosion” can happen days or even weeks later. This occurs when the new skin cells that grew over the scratch do not attach firmly. Waking up and opening your eyes can rip those cells off again, causing the same intense pain as the original injury. Research published in the journal Cornea found that up to 10 percent of people with a simple scratch will experience this recurrence at some point.
If the pain does not start to improve after 24 hours, or if it gets worse, that is a sign something else is going on. You may have developed an infection or the scratch may be deeper than first thought. Do not assume it will heal on its own at that point.
What Should You Do Immediately After Scratching Your Eye?
Do not rub your eye. Rubbing can turn a surface scratch into a deeper wound. The first thing to do is try to blink several times. Your natural tears may wash out any small particle that is still on the surface. If that does not help, you can rinse the eye gently with clean water or a sterile saline solution for 15 to 20 minutes.
Do not put anything into your eye that is not sterile. Do not use eye drops that claim to “get the red out.” Those drops contain vasoconstrictors that shrink blood vessels but also dry out the eye and slow healing. Sterile lubricating drops without preservatives are safe to use for comfort. Look for “artificial tears” on the label.
The most important step is to see an eye doctor or go to urgent care. A healthcare provider can put a dye called fluorescein in your eye. This dye glows under a blue light and shows exactly where the scratch is and how deep it goes. They can also check for any foreign body that is still stuck under your eyelid. Without that exam, you cannot know how serious the injury really is.
What Does the Treatment for a Scratched Eye Involve?
Treatment depends on the size and depth of the scratch. For a minor abrasion, the standard care is antibiotic eye drops or ointment to prevent infection. Doctors used to recommend patching the eye shut, but the American Academy of Ophthalmology now advises against it. Studies have shown that patches do not speed healing and can actually increase the risk of infection.
For larger or more painful scratches, your doctor may prescribe a topical antibiotic drop that you use several times a day. They may also give you a cycloplegic drop, which temporarily relaxes the eye muscle and reduces the painful spasms that happen when light hits the injured area. This drop can make your vision blurry for several hours, so you should not drive after getting it.
Pain management is usually handled with over-the-counter oral pain relievers like ibuprofen or acetaminophen. Do not use numbing eye drops at home. Those drops, like proparacaine or tetracaine, are only for use in a doctor’s office. Using them at home can mask a worsening injury and actually damage the cornea with repeated use, leading to permanent vision problems.
| Treatment | Purpose | Important Note |
|---|---|---|
| Antibiotic drops/ointment | Prevent bacterial infection | Use exactly as prescribed |
| Lubricating artificial tears | Reduce friction during blinking | Use preservative-free only |
| Oral pain relievers | Manage discomfort | Ibuprofen or acetaminophen are standard |
| Eye patch | No longer recommended | May increase infection risk |
What Are the Signs That a Scratched Eye Is Getting Worse?
You need to watch for specific warning signs that the injury is not healing correctly. If the pain becomes more intense after the first 24 hours instead of less, that is a red flag. A spreading redness in the white of the eye or any yellow or green discharge is a sign of infection. Do not ignore these symptoms.
Another serious sign is a white or gray spot on the cornea that you can see in the mirror. This can indicate a corneal ulcer, which is an open sore on the cornea that requires aggressive treatment. Vision changes that do not improve, such as persistent blurriness or seeing halos around lights, also warrant immediate medical attention.
If you wear contact lenses, you must stop wearing them until your eye is fully healed and your doctor says it is safe. Wearing contacts over a healing scratch can trap bacteria against the cornea and cause a severe infection called a corneal ulcer. Some of these infections can lead to permanent scarring or vision loss if not treated quickly.
Frequently Asked Questions
Can a scratched eye heal on its own without treatment?
Minor scratches can heal on their own within a few days, but you should still see a doctor to confirm there is no infection or embedded debris.
Should I go to the ER for a scratched eye?
Go to the ER if you have severe pain, vision changes, or if something hit your eye at high speed like metal or glass.
Can you sleep with a scratched eye?
Yes, you can sleep, but do not tape the eye shut unless your doctor specifically tells you to do so.
How do doctors check for a scratched eye?
Doctors use a yellow dye called fluorescein and a blue light to see the scratch clearly on the cornea surface.
