1. A monitoring apparatus for an eye of a patient, comprising:

  • a) a soft contact lens formed of a transparent substrate and having a center;

    b) a first arcuate pattern of resistive traces printed onto an outer surface of the lens substrate and concentric about the center of the lens;

    c) a second arcuate pattern of resistive traces printed onto an inner surface of the lens substrate and concentric about the center of the lens and wherein, with respect to the eye of the patient, traces of the first and second arcuate patterns are visually aligned;

    d) one or more conductive traces printed on the lens, wherein the one or more conductive traces connect the first pattern to the second pattern, ande) a signal monitor that is in signal communication with the first and second arcuate patterns of resistive traces and that is energizable to provide a signal indicative of the lens shape according to electrical current through the first and second arcuate patterns of resistive traces.
