How does REBRIGHT Eye Drops work? To administer REBRIGHT Eye Drops, you should wash your hands with soap and water first. The drops interact with the tears in your eyes from the moment you drop them in your eyes. When drops spread, they moisten and lubricate the surface of your eyeballs. And then active ingredients in it begin to work. Brimonidine, for example, could efficiently relieve redness and irritation. It can also reduce pressure inside the eyes to prevent open-angle glaucoma or ocular hypertension. What makes the REBRIGHT Eye Drops your best choice?
