“I only scratched my eye a little. It will be fine.”
That is what many people think after accidentally touching, rubbing, or scratching their eye.
Then the watering starts.
The eye becomes painfully sensitive to light.
It feels as though something is stuck inside it.
And suddenly, opening the eye becomes difficult.
What may have seemed like a tiny injury could actually be a corneal abrasion—a scratch on the surface of the cornea.
And because the cornea contains a very high concentration of nerve endings, even a small abrasion can be surprisingly painful.
What Can Scratch Your Eye?
A corneal abrasion can happen more easily than many people realise.
Common causes include:
✓ Fingernails
✓ Makeup brushes or applicators
✓ Dust or small particles
✓ Tree branches or plant material
✓ Rubbing the eyes
✓ Eye injuries during sports or other activities
✓ Contact lenses that are poorly fitted, overused, or improperly cared for
✓ Certain workplace activities involving tools or flying particles
Sometimes, the injury happens so quickly that you may not even realise exactly what scratched your eye.
How Do You Know You May Have One?
A corneal abrasion can cause symptoms that are difficult to ignore.
You may experience:
Pain or stinging
Excessive watering
Redness
Sensitivity to light
Blurred or hazy vision
A sensation that something is trapped in your eye
Swollen eyelids
That “something is in my eye” feeling can be particularly frustrating.
You may keep checking your eye.
You may blink repeatedly.
You may want to rub it.
Don’t.
The Hidden Truth: Rubbing Can Make Things Worse
When something feels wrong in your eye, your first instinct may be to rub it.
But if the cornea has already been scratched, rubbing can further irritate the injured surface and interfere with healing. The American Academy of Ophthalmology specifically advises avoiding eye rubbing while a corneal abrasion is healing.
So if your eye suddenly becomes painful after an injury:
Hands away from the eye.
Don’t Try to “Dig Out” the Problem
Another common reaction is to use your fingers, tissue, cotton buds, or another object to search for whatever may be causing the discomfort.
This can cause additional injury.
If something appears to be stuck in the eye—especially after an injury—don’t try to force it out yourself.
A professional eye examination can determine whether there is a foreign body, a corneal abrasion, or another injury.
How Is a Corneal Abrasion Diagnosed?
A professional eye examination can reveal whether the cornea has been scratched.
One common method involves fluorescein dye, which highlights areas where the surface of the cornea has been damaged. An eye-care professional may also examine the eye using a slit lamp to assess the injury more closely.
This is important because eye pain does not always mean a simple scratch.
A foreign body, infection, deeper injury, or another eye condition may produce similar symptoms.
What Happens During Treatment?
Treatment depends on the cause and severity of the injury.
Depending on what is found during examination, an eye-care professional may recommend lubricating drops or ointment, prescribe medication when appropriate, remove a foreign body, or use other measures to support healing. Contact lens wearers may need specific treatment because of the increased infection risk associated with contact lens-related corneal injuries.
Most uncomplicated surface abrasions heal relatively quickly, but the healing time depends on the size and severity of the injury.
Do not self-prescribe eye medication simply because your eye is red or painful.
The right treatment depends on what is actually happening.
What About Contact Lens Wearers?
If you wear contact lenses and develop eye pain, redness, watering, light sensitivity, or blurred vision after a possible abrasion, take it seriously.
Do not continue wearing your usual contact lenses while the eye is healing unless your eye-care professional tells you otherwise.
Contact lens-related corneal injuries can become infected, so professional assessment is particularly important.
When Should You Seek Urgent Eye Care?
Don’t ignore an eye injury if you have:
✓ Significant or worsening eye pain
✓ Reduced or blurred vision
✓ Severe sensitivity to light
✓ Persistent watering or redness
✓ A foreign object that won’t come out
✓ An injury involving a sharp object
✓ An injury from a high-speed particle
✓ Chemical exposure
✓ Symptoms that are not improving
Severe eye pain, significant vision loss, penetrating injuries, and chemical injuries require urgent medical attention.
If a chemical enters your eye, immediate irrigation with clean water is critical while seeking urgent medical care.
Protect Your Cornea Before It Gets Hurt
A few simple habits can reduce the risk of eye injuries.
✓ Wear appropriate protective eyewear when using power tools.
✓ Use eye protection during activities where particles can enter the eye.
✓ Be careful when applying eye makeup.
✓ Keep fingernails appropriately trimmed, especially around young children.
✓ Follow proper contact lens hygiene and replacement instructions.
✓ Avoid rubbing your eyes unnecessarily.
✓ Don’t ignore persistent eye discomfort.
Your cornea may be tiny.
But protecting it matters enormously to your vision.
Sometimes it takes only a second.
A child’s fingernail.
A makeup brush.
A dusty environment.
A careless rub.
A poorly handled contact lens.
And suddenly, your eye hurts.
So if your eye feels as though something is stuck inside it after an injury, don’t assume it will simply disappear.
Don’t rub. Don’t dig. Don’t guess.
Get your eye properly examined.
Because when it comes to your eyes, a tiny scratch deserves serious attention.
Clear vision is not just about seeing better—it is about living better.
