Conjunctivitis, commonly known as "pink eye," is an inflammation of the conjunctiva, the thin, transparent membrane covering the white part of the eye and the inner surface of the eyelids. It can be caused by infections, allergies, or irritants.

Global prevalence: Conjunctivitis is a common condition, with viral conjunctivitis being the most widespread.
Seasonal spikes: Viral conjunctivitis is more common during outbreaks, while allergic conjunctivitis peaks during allergy seasons.
Age distribution: It affects all age groups, though children are particularly susceptible due to close contact in schools.

1. Infectious

Viral: Adenoviruses are the most common cause.
Bacterial: Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus species.

Perennial allergies caused by mold, pet dander, or dust mites.
