Biofinity by CooperVision are monthly disposable soft contact lenses. They are a flexiwear lens which allows the flexibility of sleeping in the lenses for a number of nights. This is possible due to the high level of oxygen which is permeated by the Biofinity contact lens. They have an aspheric design for sharper vision. The Aquaform material allow a comfortable fit and the 46% water content gives good hydration. There is a visibility tint to allow the wearer an easy view of the lens inside the case.
