What is Allergic Conjunctivitis?
- The conjunctiva (the film that covers the eyes) is stimulated by allergens and causes allergic reactions
- Similar to acute conjunctivitis commonly known as "pink eye", but allergic conjunctivitis is not contagious
- It may recur repeatedly
Causes
- Allergens in the surrounding environment or the air enter the eyes and cause sensitivity
- It is also possible that the patient’s immune system is stimulated and has abnormal reactions
Categories
Symptoms

- Severe patients are more likely to damage the conjunctiva and corneal ulcers
High Risk Group
- Allergic Rhinitis or Eczema
- Wearing contact lens
- Allergic constitution (Asthma/Eczema)
- Family history of allergies
Treatment
- Prevent contact with allergens: pollen, dust mites, animal hair, etc.
- Cold compress eyes: low temperature can constrict blood vessels and reduce allergic reactions
