1. An accommodating contact lens comprising:
an optical chamber;
an eyelid-engaging chamber coupled to the optical chamber; and
one or more channels extending between the optical chamber and the eyelid-engaging chamber;
wherein the optical chamber and the eyelid-engaging chamber each comprise a positive pressure and wherein a soft contact lens material is arranged to be selectively engaged with an eyelid in order to provide incremental increases in optical power;
wherein top and bottom surfaces of the accommodating contact lens extend over the optical chamber and the eyelid-engaging chamber;
wherein said positive pressure of the optical chamber and the eyelid-engaging chamber provides a deflection of an upper membrane of the optical chamber and an upper membrane of the eyelid-engaging chamber in order to facilitate fluidic communication and responsiveness between the optical chamber and the eyelid-engaging chamber.
