This multi-purpose contact lens solution is designed to work with your eyes and mimic your natural moisture—it has the same pH balance as your tears. It also functions with your eye’s normal lubrication for up to 20 hours of comfortable wear, and a dual disinfection system keeps your contacts squeaky clean until you’re ready to toss them out. As an added bonus, this solution keeps your eye’s proteins in their native active state while removing denatured proteins (proteins that have been damaged due to external stress), for a more complete approach to optical health.
