What type of eye drops are typically used to treat allergic conjunctivitis?

Antihistamine eye drops are specifically designed to alleviate the symptoms associated with allergic conjunctivitis. This condition occurs when the eyes come into contact with allergens, leading to irritation and inflammation. Antihistamines work by blocking the action of histamine, a substance in the body that is released during an allergic reaction. By doing so, these drops help reduce redness, itching, and swelling of the eyes, providing relief to individuals suffering from this condition.

In the context of the other options: antibiotic eye drops are used to treat bacterial infections, corticosteroid eye drops may be prescribed for more severe inflammation but are not the first-line treatment for allergies due to potential side effects with long-term use, and moistening eye drops, or artificial tears, help relieve dryness but do not specifically address allergic reactions. Therefore, the choice of antihistamine eye drops is most appropriate for treating allergic conjunctivitis.
