Why Are My Baby's Eyes Red?

Published in Baby Eye Health 2 mins read

Your baby's red eyes can result from several factors, often related to irritation or infection. According to the information available, the most common causes of red eyes in children are viral or bacterial conjunctivitis, commonly known as pink eye.

Common Causes of Red Eyes in Babies

Here are the primary reasons why your baby's eyes might be red:

Viral Conjunctivitis (Pink Eye)

  • Cause: A viral infection, similar to a common cold, can affect the eye’s conjunctiva (the thin, clear membrane covering the white of the eye and the inner surface of the eyelid).
  • Symptoms: Aside from redness, you may also notice:
    • Watery discharge
    • Gritty or itchy sensation in the eye
    • Swollen eyelids
  • Transmission: Highly contagious, spreads easily through contact with infected secretions.
  • Solution: Often resolves on its own but consult a pediatrician for guidance.

Bacterial Conjunctivitis (Pink Eye)

  • Cause: A bacterial infection of the conjunctiva.
  • Symptoms: Redness is accompanied by:
    • Thick, yellow or green discharge
    • Crustiness around the eyelids
    • Eye discomfort
  • Transmission: Highly contagious, spreads easily through direct contact.
  • Solution: Antibiotic eye drops or ointment prescribed by a doctor are typically necessary.

Other Possible Factors

While pink eye is the most common cause, other reasons for red eyes in babies might include:

  • Irritation: From environmental factors such as smoke, dust, or allergens.
  • Dryness: Lack of tear production or exposure to dry air.
  • Trauma: A minor injury to the eye.
  • Allergies: An allergic reaction to pollen, pet dander, or other substances.

What To Do

If your baby’s eyes are red, it’s important to:

  1. Observe: Note any other symptoms, such as discharge, swelling, or behavior changes.
  2. Clean: Gently clean the eye area with a clean, damp cloth.
  3. Consult: See your pediatrician to identify the underlying cause and get appropriate treatment, especially if the symptoms persist or worsen.
