A corneal abrasion is a scratch on the eye's cornea. The cornea is the clear, protective covering over the iris, which is the colored part of the eye, and the pupil -- the black circle in the middle of the eye.
It's important both for vision and for protecting the eye. If you poke your eye or if something gets trapped under your eyelid -- such as dirt or sand -- your cornea may become scratched. When it does, it can cause significant pain and discomfort.
Causes of Corneal Abrasion?
Many situations can cause a corneal abrasion, including:
- Being poked in the eye, for instance by a fingernail, plant, or makeup brush
- Dirt, sand, sawdust, ash, or some other foreign matter blowing into your eye and getting caught under the eyelid
- Chemical burns
- Aggressively rubbing your eye
- Poor fitting or dirty contact lenses
- Certain types of eye infections
- Not protecting the eyes during surgery while under general anesthesia; if your eyes are not closed during surgery, the cornea can dry out, making it more prone to corneal abrasion.
Symptoms of a corneal abrasion do not always happen immediately. As a result, it's often hard to know what caused it.
Symptoms of Corneal Abrasion
Once you've had a corneal abrasion, you're not likely to forget the unrelenting pain and discomfort it can cause. Symptoms of corneal abrasion may include:
- Feeling like you have sand or grit in your eye
- Eye pain, especially when opening or closing your eye
- Tearing and redness
- Sensitivity to light
- Blurred vision or loss of vision
