Provides long acting, soothing relief from sore, gritty dry eyes. Because of the long action of the liquid gel, only 3 to 4 applications per day generally give complete protection against dry eye discomfort. Contains a non-irritating preservative which prevents microbial contamination and turns to water and oxygen when Genteal Gel is dropped onto the eye. Instructions: Hold tube vertically. Instil one drop three to four times daily as required.
