🆚 Go to Comparative Table 🆚

The main difference between pink eye and allergies is the cause of the inflammation. Pink eye, also known as conjunctivitis, can be caused by bacteria or a virus, while allergies are triggered by various irritants such as pollen or pets. Both conditions can cause redness, itchiness, and increased tear production in the eyes. Here are some differences and similarities between the two:

Differences:

  • Pink eye is an infection caused by bacteria or a virus, while allergies are triggered by irritants.
  • Intense itching of the eyes is a symptom associated only with eye allergies.
  • Pink eye caused by viral conjunctivitis often starts in one eye and spreads to the other, while eye allergies usually affect both eyes at once.
  • Allergic conjunctivitis is not contagious, unlike bacterial or viral pink eye.

Similarities:

  • Both conditions can cause redness, itchiness, and increased tear production in the eyes.
  • Both conditions can cause a watery or stringy mucus discharge.

To determine whether you or your child has pink eye or allergies, it is essential to consult a medical professional for a proper diagnosis and appropriate treatment.
