When contact lenses are soaked in OPTI-FREE^® RepleniSH^® MPDS, the surface of the lens is reconditioned by retaining TearGlyde^™, a proprietary reconditioning system on the surface of the lens. This allows a thin layer of moisture from the eyes' natural tears to be maintained on the lens surface throughout the day. The solution may be used with silicone hydrogel and soft contact lenses.
