During which season is pink eye most commonly experienced?

The correct answer is spring. This season is associated with increased pollen counts from blooming plants, which can trigger allergic reactions in many individuals, leading to a higher incidence of conjunctivitis, commonly known as pink eye. Allergic conjunctivitis is often more prevalent in the spring due to the higher exposure to allergens such as pollen, dust mites, and mold, which are particularly abundant during this time of year.

While the other seasons can also lead to instances of pink eye, particularly through viral or bacterial infections, it is the spring that notably correlates with a rise in cases due to seasonal allergies impacting many people's eyes.
