ABSTRACT A system and method for cleaning, conditioning, storing and wetting rigid gas permeable contact lenses is provided. The system includes a cleaning, conditioning and storing solution and a separate wetting solution. Both solutions contain hydrophilic disinfectants or preservatives which do not inhibit proper wetting of rigid gas permeable contact lenses. The lenses are stored in the cleaning, conditioning and storing solution during nonwearing periods. This storage also acts as a secondary ox backup cleaning treatment to help remove any residual contaminants after the primary cleaning with this solution. In accordance with another embodiment of the invention, a preservative system is provided for a contact lens solution that comprises high purity benzyl alcohol.
