Which of the following is an ocular side effect associated with alpha-2 agonists?

Explanation:
Alpha-2 agonists used in glaucoma, such as brimonidine and apraclonidine, lower intraocular pressure by reducing aqueous humor production. A common ocular adverse effect in some patients is an allergic or hypersensitivity conjunctivitis, due to the drug or its preservative components, presenting with itching, redness, tearing, and eyelid swelling. While systemic effects like low blood pressure, dizziness, or headache can occur if the medication is absorbed into the circulation, these are not ocular side effects. Therefore, allergy development best fits the question.
