Visine

**Visine** is a non-specific over-the-counter ophthalmic product brand rather than one defined drug substance. The brand includes redness-relief, allergy-relief, lubricating dry-eye, and multi-symptom eye-drop formulations with different active-ingredient compositions. For example, the classic redness-relief formulation contains tetrahydrozoline hydrochloride, an imidazoline sympathomimetic that constricts superficial conjunctival blood vessels; other Visine products are lubricant formulations or contain additional allergy-relief agents. The provided 2016 study evaluated a specific prototype lubricant formulation containing glycerin, hypromellose, polyethylene glycol 400, and polyquaternium-42 preservative, not every product marketed under the Visine name. Visine is currently a Kenvue consumer-health brand. ([visine.com](https://www.visine.com/))
