Antihistamine eye drops are commonly used to treat allergic conjunctivitis because they work by blocking the action of histamine, a substance that the body releases during an allergic reaction. When the eyes come into contact with allergens, such as pollen or pet dander, histamine can cause symptoms like itching, redness, and swelling. Antihistamine eye drops provide targeted relief by reducing these symptoms, making them a practical choice for managing allergic conjunctivitis.

Antibiotic eye drops are designed to treat bacterial infections, not allergic reactions, which is why they are not effective for allergic conjunctivitis. Steroid injections may help reduce inflammation in various conditions, but they are generally not the first line of treatment for allergic conjunctivitis due to potential side effects with systemic use and the availability of safer alternatives. Daily use of contact lenses does not treat allergic conjunctivitis; in fact, wearing contacts might exacerbate discomfort if the eyes are already irritated from an allergic reaction. Therefore, antihistamine eye drops stand out as the most appropriate treatment for alleviating the symptoms of allergic conjunctivitis.
