Inspired by the biology of your eyes, it incorporates a lubricant naturally found in the eye and is pH balanced, just like healthy tears. It nourishes, cleans, removes proteins, rinses, disinfects and preserves your lenses. While your lenses are immersed in the solution, the formula envelops your lenses in a cushion of moisture, helping you feel comfortable wearing them all day. Includes a lens case; discard any remaining solution after opening the bottle. Use within 90 days
