Abstract
A method and composition for reducing evaporation of an aqueous layer from the surface of the eye. The method comprises applying a gel of oil and wax over the eye, preferably in the form of a meta-stable oil in water emulsion in a dosage not exceeding 100 microliters. The gel is formed by gelling a hydrocarbon oil with a wax, preferably dispersed in aqueous medium at a pH of at least about 8.0.
