What is a scratched cornea?

A Closer Look at a Scratched Cornea

The eye is a complex and delicate organ, protected by a clear shield known as the cornea. But what happens when this protective shield is damaged? Let’s delve into the phenomenon of a scratched cornea, often termed as a corneal abrasion.


1. Understanding the Cornea

The cornea is the eye’s outermost layer. It’s transparent and covers the front portion of the eye, helping to focus incoming light. Because of its exposed position, the cornea is susceptible to injuries.

2. What Causes a Scratched Cornea?

  • Foreign Objects: Dust, sand, or other small particles can cause a corneal abrasion.
  • Contact Lenses: Wearing damaged lenses or mishandling them can result in abrasions.
  • Physical Trauma: A poke in the eye or rubbing the eyes aggressively can damage the cornea.

3. Symptoms of a Corneal Abrasion

  • Pain and Redness: A strong, persistent pain, often accompanied by redness, is common.
  • Tearing and Sensitivity: The eye might produce more tears and become sensitive to light.
  • Blurry Vision: Vision may become temporarily impaired.

4. Treatment Options

  • Seek Medical Attention: If you suspect a corneal abrasion, visit an ophthalmologist or optometrist immediately.
  • Antibiotic Eye Drops: To prevent infection, a doctor may prescribe antibiotic drops.
  • Lubricating Eye Drops: These soothe the eye and facilitate the cornea healing.
  • Avoid Rubbing: Refrain from touching or rubbing the affected eye.

5. Prevention Tips

  • Protective Eyewear: If you’re engaged in activities with potential eye hazards, like woodworking or sports, wear safety glasses.
  • Handle Contacts Carefully: Always ensure your contact lenses are clean and undamaged before wearing.
  • Avoid Rubbing Eyes: If you feel an irritant in your eye, try blinking or rinsing with saline solution instead of rubbing.


A scratched cornea, while painful, is usually not a major cause for concern. With prompt and appropriate treatment, most corneal abrasions heal within 24 to 48 hours. However, prevention remains the best strategy. By taking simple precautions and being aware of potential hazards, you can reduce the risk of injuring your precious cornea.
