摘要
Problem to be solved: to provide a method and apparatus capable of less calibration time. A method and apparatus for enabling monitoring of other eyeball characteristics other than IOP are provided.A contact lens measuring apparatus comprises a sensor having a projection toward the cornea.The measuring device is flattened by the closed eyelid and is so flexible that the projection produces a bump of the cornea.The force generated on the projection is measured by the sensor.A constant acceleration and deceleration model of the eyelid is applied to the movement of the eyelid, and the mechanical model is applied to the cornea, and the tension of the cornea is determined and estimated from the force measured in the closed state of the eyelid, thereby giving true intraocular pressure.In the alternative, the protrusions are characterized by discontinuity of the shape or the sensor is subdivided and each sub sensor is characterized by different shaped protrusions.The corneal tension may be obtained by the linear or extrapolated values or by different protrusions by linear extrapolation.Diagram
