Which of the following is a common optometric intervention for managing allergic conjunctivitis?

• A. Oral steroids
• B. Antihistamines
• C. Contact lenses
• D. Prescription sunglasses

Answer: (B)

Antihistamines are a common and effective optometric intervention for managing allergic conjunctivitis because they block the action of histamine, a chemical released during an allergic reaction that contributes to symptoms such as itching, redness, and swelling of the conjunctiva. By inhibiting histamine, these medications help alleviate discomfort and reduce inflammation associated with this condition. Antihistamines can be administered orally or as topical eye drops, and both forms are beneficial for treating allergic conjunctivitis.

In contrast, while oral steroids can reduce inflammation, they are typically reserved for more severe cases or chronic conditions due to potential side effects. Contact lenses can aggravate symptoms during an allergic reaction, as they may trap allergens against the eye. Prescription sunglasses generally provide protection from bright light and dust but do not address the underlying allergic response, making them less relevant for treating allergic conjunctivitis directly.
