What it is
A corneal abrasion is a graze or scratch on the cornea, the clear dome at the front of the eye. The cornea is very sensitive, so even a small scratch can be painful, but most heal quickly because the surface repairs itself rapidly.
Common symptoms
Symptoms usually come on suddenly after something contacts the eye.
- Pain and a strong feeling that something is in the eye
- Watering and redness
- Sensitivity to light
- Blurred vision or difficulty keeping the eye open
Causes
Common causes include a poke from a fingernail, dust, grit or sand, tree branches, and contact lenses, especially if worn too long or not cleaned well. Dry eyes can also make the surface more prone to grazing.
Self-care and when to seek urgent care
Do not rub the eye, and avoid contact lenses until it heals. Most minor scratches settle within a day or two. Seek urgent care if a chemical has splashed into the eye (rinse with water immediately and get help), if something is stuck in the eye, if there is a high-speed injury, or if pain or blurring is severe or not improving, as treatment can prevent infection.
Frequently asked questions
How long does a scratched eye take to heal?
Most minor corneal abrasions heal within 24 to 48 hours. See a clinician if pain or blurring is severe, an object is stuck, or it is not improving.
What should I do if I scratch my eye?
Do not rub it, avoid contact lenses, and protect it from bright light. If a chemical splashed in, rinse with clean water straight away and seek urgent help.
Can a scratched eye get infected?
A scratch can occasionally become infected, which is why severe, worsening, or non-healing symptoms should be assessed, especially in contact lens wearers.
