 | In simple terms, a corneal abrasion is a scratch on the cornea, which is the front part of the eye. The cornea plays a key role in focusing on light to allow you to see. When the cornea becomes scratched, it can lead to a variety of symptoms from mild to more serious. Below is more information on the causes of a corneal scratch, symptoms, and treatments. |
Causes
Many things can scratch the cornea of your eye. For example, contact with sand, dirt, and wood shavings can scratch your eyes. These foreign bodies can blow into your eye and cause a scratch. In other cases, an object may scratch the eye, such as a tree branch.
You can also scratch your cornea by putting in and taking out your contact lenses. Putting on eye makeup, such as mascara, can also lead to a corneal abrasion if you accidentally bump your eye with the wand. Even something as simple as rubbing your eye can lead to a scratch by your fingernail.
The abrasion can occur due to contact with something, such as dirt or sand, but it can also develop after something gets in your eye if you rub the eye. The bottom line is when you put anything near your eye, you can potentially scratch the cornea if you are not careful.

Prevention
Corneal abrasions are a common type of eye injury. You can take steps to reduce your risk. Consider the following tips:
Use protective eyewear: Make sure to wear appropriate eyewear when doing activities where objects, dust, or sand could fly into your eye. Also, wear protective eyewear when engaging in certain sports that have the potential to injure your eyes, such as racquetball, hockey, and baseball.
Keep fingernails short: Long fingernails can easily scratch your eyes. Keep nails well-trimmed to reduce the risk.
Use caution with contacts: Take your time when putting your contacts in and taking them out. Rushing may increase the risk of scratching your cornea.
Pay attention when you have objects near your eyes: Pay close attention to what you are doing when you have tools near your eyes. For example, if you are tweezing your eyebrows or putting on eye makeup, focus on the task to reduce your chances of having your hand slip and scratching your eye.
