ABSTRACT:
The present invention provides solutions containing dexpanthenol in combination with xylitol, preferably further including a viscosity-enhancing agent to make solutions viscous so that the viscous solutions are not only capable of cleaning, disinfecting, and/or rinsing a contact lens in a lens case but also capable of cleaning and lubricating the contact lens directly in an eye. Such solutions can provide to the user an ability to clean and to rewet lenses anytime anywhere even without taking them out.
