receiver closes an electrical circuit not shown to supply electrical energy through the second and third electrical wires 117 and 118 to the first and third electrically conductive zones of the sensing member the energizing of the central pattern of metallization 75 causes the central portions of the inner and outer film layers 51 and 61 respectively to contract thus moving the central portion of the sensing member toward a less curved condition this applies pressure to the cornea 33 in the direction of the lens 26 of the eyeball 12 the intraocular pressure within the eyeball resist such deformation of the cornea so that the deformation of the central portion of the sensing member cannot fully take place as would otherwise be the case in any case deformation of the central portion of the sensing member 50 causes tension in the film layers 51 and 61 between the second and third electrically conductive zones dependent upon the resistance provided by intraocular pressure within the eyeball the amount of tension created is directly proportional to the intraocular pressure within the eyeball this tension creates a corresponding electrical potential between the second and third electrically conductive zones which is directly proportional as well to the intraocular pressure within the eyeball this electrical potential is sensed by the transmitter receiver and is transmitted by an electrical signal radio wave light plus or by any other suitable means to the microcontroller in the vicinity which records the reading the cycle of operation is repeated at the selection of the physician as controlled by the microcontroller so that repeated readings are taken over the test period which as noted may be several days a week or more as a consequence the readings so produced are employable to calculate.
