What Causes Cornea Pain? How to Get Your Eye Pain Under Control

Whether you're experiencing minor discomfort or extreme pain, click here to learn more about the most common causes of cornea pain.

Quick, think about the places where you have the most pain. You may think about your feet or your lower back, and you should.

But your corneas have 7000 nerve terminals per square millimeter. Your corneas are 300 to 600 times more sensitive than any spot on your skin. 

Cornea pain can be debilitating, making it hard to see, let alone work. But you can find ways to diagnose and treat your pain. 

What are the most common causes of cornea pain? What are some corneal diseases you can develop? What should you do if you have a condition like glaucoma? 

Answer these questions and you can find the best eye surgeon to treat your pain. Here is your quick guide.


The cornea is at the front of the eye, so objects that get into the eye can scrape it. Dust, hair, and contact lenses can leave scratches that cause significant pain for several days. Most scratches heal within a few days, as cells in the cornea grow back quickly. 

However, a blow to the eye can create a deep scratch. The scratch may not heal, and the pain may make you unable to see without pain. 

You should go to the doctor if you ever scratch your eyes with your fingernails or receive a blow to your eye. An eye doctor can conduct an examination and give you eye drops so your cells recover.

Corneal Disorders

You can develop a few different disorders that cause pain and impair your sight. You can get a bacterial or viral infection in your eye, including a herpes infection. 

An infection can form an ulcer on your cornea. The ulcer can make your eye red and cause you to cry when you don’t intend to. Infections can also cause blisters, which can rapture and make your vision blurry. 

Take a close look at your eye if you are experiencing pain. If you notice discoloration or a blister in your eye, you should go to your eye doctor. You may need an eye surgeon to perform corneal surgery so your blister is removed.


Glaucoma occurs when fluid builds up inside the eye. The fluid can make your eye cloudy, and it can damage your optic nerves. Over time, you may lose vision, even if your cornea is working fine. 

Glaucoma can occur with or without eye pain. You should get eye exams every year to monitor the state of your eyes. You can get a cornea transplant or receive cornea surgery to reverse your glaucoma.

The Most Common Causes of Cornea Pain 

Many medical problems can cause cornea pain. You can scratch or damage your eye by accident, leaving marks on your cornea. These marks can heal within a few days. 

However, a corneal disorder like a viral infection is a more serious problem. You need to take eye drops and talk to your doctor to control your infection.

You may develop glaucoma due to old age, which can make you blind. Go to an eye doctor for regular examinations and get surgery when you need it.
