Alcon presents the most doctor-recommended brand of contact solutions: Opti-Free Replenish Multi-Purpose Disinfecting Solution. It contains a unique formula that helps maintain a shield of moisture between your contact lenses and your eyes, for up to 14 hours. With 14 hours of moisture, the solution gives you the comfort you need to make it through your day. When your contacts are soaked in Opti-Free Replenish, the lens surface is reconditioned with the TearGlyde proprietary system. The TearGlyde system allows the lens surface to retain a thin layer of moisture from your tears, keeping lenses moist until you take them out. In addition to all-day lens comfort, this contact lens solution offers a high level of disinfection against both bacteria and fungi. Note: It is always safer to use the contact solution prescribed by your eye doctor. Ask your eye doctor if this contact lens cleaning solution is right for you.
