Opti-Free Puremoist Multi-Purpose Disinfecting Solution is a multi-purpose solution, perfect for rinsing, cleaning, disinfecting, storing and reconditioning patients lenses. Opti-Free Puremoist is the #1 doctor recommended multi-purpose solution on the market. The Opti-Free Puremoist solution includes the exclusive 2D formula that uses Polyquad and Aldox dual disinfectants to eliminate microorganisms that could potentially lead to eye infections. The Hydraglyde Moisture Matrix surrounds the patients lens in long lasting moisture, providing constant comfort throughout the day and creates a barrier to keep out harmful deposits and debris. Opti-Free Puremoist is the only one of the three patented Opti-Free formulas that includes Hydraglyde Moisture Matrix, deeming it the most effective solution for everyday contact users looking for all day moisture and relief. Compared to standard saline solutions that will only rinse the contact lens, Opti-Free Puremoist solution is meant to thoroughly clean contact lenses for comfort from morning until night. This solution works great with silicon hydrogel and soft contact lenses. These lenses may be left in the solution in an unopened case for up to 30 days before having to clean and disinfect again. 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. Opti-Free strives to continue providing patients with the newest and most effective contact lens products on the market for dry and irritated eyes.
