When your eyes sting or feel itchy and it doesn't seem to go away, there's a good chance you have a corneal abrasion. A common reason people visit an eye doctor, this is a scratch on the clear layer of the eye, which is known as the cornea. To better understand what this means, here's what you need to know. 

What Are the Basics?

The cornea is the topmost layer of the eye, and it's designed to be the first line of defense, protecting the pupil and iris. There are numerous nerve endings, so when there's an abrasion on it, it stings no matter if your eyelid is open or closed. Even light hurts and generates a burning sensation. 

What Are the Most Common Causes?

As any eye doctor will tell you, almost anything can cause corneal abrasions. However, the most common causes are foreign debris like sand, ash, or dust; dirty contact lenses; getting poked with a makeup brush or writing utensil; or even rubbing your eye too harshly. 

How Can You Treat the Condition? 

Depending on the severity and pain level of the abrasion, eye doctors can prescribe medicated eye drops to minimize discomfort and prevent an infection. Most minor ones will heal within three days, if not sooner. You may or may not need to use an eyepatch, but if it's a deep one, they may tape it shut to block out more possible irritants and bright lights. 

While it can be treated, preventing one is often easier. Wear eye protection when there's a possibility of dealing with any debris, whether you're mowing the lawn or woodworking. Also, be careful when applying eye makeup or putting in your contact lenses.
