CooperVision's Biomedics XC contact lenses are 1 to 2 week disposable contacts that are worn as daily lenses for up to two weeks and discarded.  Using their patented PC Technology, Biomedics XC lenses are made of a unique material containing molecules of phosphorylcholine, which is found naturally in human cell membranes.  The molecules attract and surround themselves with water, keeping your eyes wet, healthy and comfortable throughout the day.
