A. Peel back the foil closure to reveal the lens. b. Place a finger on the lens and slide the lens up the side of the bowl of the lens package until it is free of the container. Occasionally, a lens may stick to the inside surface of the foil when opened or to the plastic package itself. This will not affect the sterility of the lens. It is still perfectly safe to use. Carefully remove and inspect the lens following the handling instructions.
