An electronic or powered ophthalmic lens includes one or more systems havingone or more batteries or other power sources, power management circuitry, oneormore sensors, clock generation circuitry, control algorithms and circuitry,and lens drivercircuitry. These systems may change the state of the powered ophthalmic lens.Insystems having one or more sensors, a decision making process is required tosubstantially reduce the possibility of changing the state of the poweredophthalmic lensbased upon inaccurate, incomplete or erroneous information supplied by thesensors,changing physiologic conditions , as well as noise and/or interference frominternal andexternal sources.
