What Is Allergic Conjunctivitis?

Allergic conjunctivitis is an inflammation of the conjunctiva, the outermost layer of the eye, which is caused by an allergic reaction. It often occurs in response to seasonal pollen, pet dander, or dust mites, and it can make your eyes itchy, red, teary, and swollen.

Common Symptoms of Allergic Conjunctivitis

Allergic conjunctivitis is typically diagnosed based on your signs and symptoms. Common symptoms include:

  • Itching eyes
  • Red eyes
  • Swelling of the conjunctiva
  • Tearing
  • Burning
  • Sensitivity to light
  • Lumpy discharge

Treatment Options

Treating allergic conjunctivitis usually begins with avoiding possible triggers like pet dander, pollen or dust mites. Over-the-counter artificial tears can help if your eyes are dry or irritated. For more severe cases, your optometrist may prescribe antihistamine or steroid eye drops or an ointment to reduce the allergic response.
