Why can the eye get conjunctivitis

Conjunctivitis may be caused by pathogenic microorganism infection, allergy, chemical stimulation and other factors.

1. Pathogenic microorganism infection

patients due to bacteria, viruses, chlamydia and other pathogenic microorganism infection, can lead to conjunctivitis inflammatory reaction.

2. Allergic

patients due to eye contact allergens such as pollen, animal hair, dust, etc., may cause allergic reaction leading to vasodilation in conjunctiva, thus causing conjunctivitis.

3. Chemical stimulation

patients due to medical drugs, toxic gases and other chemicals, causing eye irritation damage, leading to leukocyte aggregation, thus causing conjunctivitis.
