What to Do If You Scratched Your Eye: First Aid

If you’ve scratched your eye, the first thing to do is rinse it gently with clean water or saline solution, avoid rubbing it, and resist the urge to touch or press on it. Most minor corneal abrasions heal on their own within 24 to 48 hours, but the scratch needs proper care to avoid infection or further damage.

Rinse Your Eye Right Away

Use clean water or a sterile saline solution to flush your eye. The Mayo Clinic recommends using an eyecup or a small, clean drinking glass positioned with its rim resting on the bone at the base of your eye socket. If you’re at a worksite with an eye-rinse station, use it. The goal is to wash out any dust, dirt, or debris that may still be on the surface of your eye.

If you feel like something is stuck in your eye, flushing is still the right first step. Don’t try to remove a particle with your fingers, cotton swabs, or tweezers. Poking around on an already-scratched cornea can make things significantly worse.

What Not to Do

The most important rule: don’t rub your eye. It feels instinctive, especially when your eye is watering and irritated, but rubbing can deepen the scratch or drag debris across the corneal surface. Beyond that, keep these in mind:

  • Don’t use eye drops without medical guidance. The American Academy of Ophthalmology notes there are no over-the-counter eye drops made specifically for eye scratches. Random drops, especially redness-reducing ones, can irritate a damaged cornea.
  • Don’t patch your eye. It used to be standard advice, but a meta-analysis found that eye patching does not improve healing rates or reduce pain. It can actually increase discomfort and takes away your depth perception.
  • Don’t wear contact lenses. If you had contacts in when the scratch happened, take them out. Leave them out until your eye has fully healed. Contact lens wear on a scratched cornea is a major risk factor for developing a serious infection.

What a Scratched Eye Feels Like

A corneal abrasion typically causes sharp pain, a gritty “something is in my eye” sensation, excessive tearing, and sensitivity to light. Your eye will likely look red, and you may find yourself squinting or struggling to keep the eye open. Some people notice slightly blurred vision in the affected eye.

These symptoms are usually worst in the first several hours. With a simple scratch from a fingernail, a makeup brush, or a piece of dust, the pain tends to resolve quickly, often within 24 hours. That rapid improvement is actually a useful signal: it tells you the scratch is healing normally rather than developing into something more serious.

Managing Pain at Home

A scratched cornea can be surprisingly painful for such a small injury. The cornea is one of the most nerve-dense tissues in your body, so even a tiny abrasion can feel intense. Over-the-counter oral pain relievers like ibuprofen or acetaminophen can help take the edge off.

Staying in a dimly lit room or wearing sunglasses can ease the light sensitivity. Blinking naturally keeps the surface of your eye moist and supports healing. If you’re tearing a lot, let it happen. Tears are your body’s built-in rinse cycle, carrying protective proteins and moisture across the scratch.

When a Scratch Needs Medical Attention

Most minor scratches heal without complications, but certain signs mean you should get to an eye doctor or emergency department promptly:

  • Vision loss or increasing blurriness that doesn’t clear with blinking
  • Severe or worsening pain, especially if it intensifies after the first day rather than improving
  • Symptoms that don’t improve within 24 to 48 hours
  • A white or hazy spot on the cornea, which can signal an infection or ulcer forming

The timing of your pain matters. A simple abrasion hurts immediately but improves steadily. An infection from a scratch follows the opposite pattern: it gets worse over time. If your eye felt a bit better yesterday but is now more painful, red, or swollen, that’s a warning sign that bacteria may have entered the wound.

How Scratches Can Become Infections

The cornea is normally well-protected, but an abrasion creates an opening where bacteria can take hold. This is especially true for contact lens wearers. Doctors should have a very low threshold for suspecting a bacterial infection in any contact lens wearer who develops a red, painful eye.

An infected scratch can progress into a corneal ulcer, which looks like an irregular, fluffy white lesion on the eye’s surface. Unlike a clean abrasion, which has sharp, well-defined borders when examined by a doctor, an ulcer appears hazier and more diffuse. Untreated corneal ulcers can cause permanent scarring and vision damage, so worsening symptoms after a scratch should never be brushed off as “still healing.”

When you do see a doctor for a corneal abrasion, they’ll typically examine your eye using a special dye that makes the scratch visible under blue light. For contact lens wearers or scratches with a higher infection risk, antibiotic eye drops or ointment are commonly prescribed as a precaution, though the evidence for routine antibiotic use in all corneal abrasions is limited.

How Long Healing Takes

Small, superficial scratches from everyday causes (a baby’s fingernail, a branch, an eyelash) generally heal within one to three days. The cornea regenerates its surface layer faster than almost any other tissue in the body. During that time, your eye may still feel slightly gritty or watery, but the sharp pain should fade noticeably within the first 24 hours.

Larger or deeper abrasions can take longer, sometimes up to a week, and are more likely to need medical treatment to prevent scarring. If you scratched your eye with something potentially dirty, like a tree branch, metal shaving, or soil-contaminated object, it’s worth getting it checked even if the pain seems manageable, because contaminated wounds carry a higher infection risk.

Preventing Future Eye Scratches

The most common causes of corneal abrasions are small particles like dust, metal slivers, wood chips, and cement fragments, according to the CDC. Wind, power tools, and overhead work send these into the eyes regularly. Wearing properly fitted safety goggles or glasses with side shields during yard work, construction, or any activity that generates debris is the single most effective prevention measure.

For contact lens wearers, careful hygiene makes a real difference. Don’t wear lenses longer than recommended, avoid inserting or removing them roughly, and skip wearing them when your eyes are very dry. Trimming young children’s fingernails is another surprisingly practical step, since infant scratches to a parent’s eye are one of the more common reasons adults end up with corneal abrasions.
