Eye Infections

Topic pages summarize public health information in plain language. They may describe common causes and treatments in general terms; your own plan of care depends on your clinician’s exam, history, and tests. Use what you read here to prepare questions—not to start, stop, or change medications or to self-diagnose.

Your eyes can get infections from bacteria, fungi, or viruses. Eye infections can occur in different parts of the eye and can affect just one eye or both. Two common eye infections are:

  • Conjunctivitis - also known as pink eye. Conjunctivitis is often due to an infection. Children frequently get it, and it is very contagious.
  • Stye - a bump on the eyelid that happens when bacteria from your skin get into the hair follicle of an eyelash.

Symptoms of eye infections may include redness, itching, swelling, discharge, pain, or problems with vision. Treatment depends on the cause of the infection and may include compresses, eye drops, creams, or antibiotics.
