Optifree puremoist 300 ml + 60ml. Product Details The high-performance formula of Opti-Free PureMoist is designed to make your lenses wearable for up to 16 hours each day, much longer than your average contact lens solution and especially helpful for those with busy lifestyles who require longer wearing time. This brilliantly formulated multi-purpose contact lens solution not only destroys lipids and protein build-up, but also creates a protective barrier on the lens. Place of Origin USA Directions To effectively use Opti-Free Puremoist, fill your lens case with solution and wet each side of the lens. Afterwards, rub each lens for approximately 20 seconds with your fingers. Next, rinse each side of the lens for about 10 seconds with steady application of Opti-Free Puremoist solution. For the final step, place the lenses in the case for at least six hours to give the solution time to thoroughly rinse and disinfect the lenses.
