What is a common trigger for allergic conjunctivitis?

• A. Dust mites
• B. Glare from bright lights
• C. Prolonged screen time
• D. Excessive eye rubbing

Answer: (A)

Allergic conjunctivitis is often triggered by environmental allergens that come into contact with the eyes, leading to inflammation and irritation. Dust mites are a well-known common trigger because they are prevalent in household environments and can be present in bedding, carpets, and upholstered furniture. When exposed to dust mites, individuals who are sensitive may experience symptoms such as redness, itching, and tearing in their eyes. In contrast, glare from bright lights, prolonged screen time, and excessive eye rubbing are not direct triggers of allergic conjunctivitis. While they may cause discomfort or exacerbate symptoms in some individuals, they do not initiate the allergic inflammatory response that characterizes allergic conjunctivitis. Thus, dust mites represent a significant environmental factor in the development of allergic conjunctivitis symptoms.
