Kids Home > Pink Eye Causes
People develop pink eye for a number of different reasons. Causes of the condition may include a viral infection, a bacterial infection, or an allergic reaction. In most cases, the causes of pink eye are related to a virus (most commonly adenovirus) or the allergens that cause both seasonal and year-round allergy symptoms.
- Herpes simplex virus
- Varicella zoster virus (the virus that causes chickenpox and shingles)
- Molluscum contagiosum.
