What can cause inflammation of the conjunctiva?

1. Allergic reactions and seasonal irritants

2. Exposure to sunlight and dust

3. Pollution and smoking

4. Genetic factors and age

The correct answer is: Allergic reactions and seasonal irritants

Allergic reactions and seasonal irritants are recognized factors that can contribute to inflammation of the conjunctiva, a condition commonly referred to as conjunctivitis. When the conjunctiva, which is the thin membrane covering the white part of the eye and the inside of the eyelids, becomes irritated or inflamed, this can lead to symptoms such as redness, itching, and watering of the eyes. Allergic reactions often stem from environmental triggers, such as pollen, pet dander, or mold, particularly during certain seasons when these substances are more prevalent. Seasonal irritants, like dust or smoke, can also cause similar responses in sensitive individuals. When these allergens or irritants come into contact with the conjunctiva, the immune system reacts, leading to inflammation. While other options mention factors like pollution, smoking, genetic predispositions, or exposure to sunlight, they are less directly associated with the primary mechanisms underlying conjunctival inflammation compared to direct exposure to allergens or seasonal irritants. Understanding the primary causes is essential in managing and treating conditions like allergic conjunctivitis effectively.
