Unique pH is a highly effective and well-respected multipurpose solution for gas permeable contact lenses. Soaking your gas permeable contact lenses in Unique pH removes dirt, protein deposits and debris. No separate daily cleaner is required. This solution conditions lenses by adjusting to the eye's natural tear pH to enhance the wettability and comfort of gas permeable contact lenses on insertion. This formula is designed to provide a soothing effect during lens wear. The solution disinfects lenses using antimicrobial agents, which destroy harmful microorganisms (germs), commonly found on the surfaces of lenses. Unique pH Multi Purpose Solution may also be used to dilute a daily protein remover for simultaneous enzymatic cleaning during conditioning. Travel-friendly bottle size for carry-on convenience.
