It is not necessary to make a buzzer sound if the measurement is short, but such a buzzer sound is unnecessary, but in this measurement it is as long as 20 seconds, so that the subject intentionally blinks etc. Preparation for measurement In order to be able to
- the target 62a is continuously arranged at the same position for a predetermined time T, and the temporal change of the eye flexing power at that time is monitored (S5).
- the time T (the time period for sampling the time-lapse data of the eye refractive power) is about 8 seconds or more, and less than about 20 seconds with less strain on the ciliary muscle for the subject eye 10 to gaze at It is.
- the reason why the time is approximately 8 seconds or more is because sufficient amount of data needs to be sampled in order to maintain the accuracy of the calculation (S 7) for finding the frequency of occurrence of the low frequency component. It is 2 0 sec.
- the buzzer beeps to notify the subject of the end of 1 cycle measurement. (Operation as a measurement pause notification unit) Stop the measurement (S 6). The subject is able to take a break after this and can relieve tension.
- the control unit 65 calculates the frequency of the high frequency component from the measurement values obtained so far (S 7). During measurement, the control unit 65 also fully operates to calculate the measurement value in order to perform measurement at 0.1 second intervals, but if measurement is paused, the control unit 65 also has room for operation. The resting time can be used to calculate the frequency of the high frequency component of the eye conditioning function status measurement that has been measured.

By doing this, it is only necessary to store one cycle of measurement data in the memory, and the storage components such as the memory in the device can be minimized, and it is not necessary to mount a large capacity memory.
- the measurement suspension is ended by the above (S 10) Next, before moving the target one step, ask the examiner whether to re-measure without moving the target (S1 1).
- control unit 65 determines whether the target position has advanced to DO + Q! 'N (in this case, whether n has advanced to 8 steps). If NO, the target is 1 step (for example, 1 step) 0.5D P) Advance (S1 3). Then, as in the previous round, return to S3 and make measurements. If YES, all measurements are finished.
- the external storage unit 69 is an example of a specialized device.
- the present invention is not limited to this.
- the external storage unit 69 may have both a CPU such as a personal computer and a memory.
- the data transmission of S 9 may be performed prior to the calculation of the eye adjustment function state in the control unit 65, and the eye adjustment function state calculation may be performed on the personal computer side.
- the purpose of the present invention is to perform calculation processing and data transmission during measurement pauses, and to minimize the burden on the control unit in the eye control function status measurement device, so that it is within the measurement break time. If data transmission and calculation processing are performed, the order of data transmission and calculation processing may be reversed in any control unit.
