Ophthalmologic apparatus

1 . An ophthalmologic apparatus comprising:

a subjective measurement optical system configured to measure a subjective refractive value of a subject eye;

an objective measurement optical system configured to measure objective refractive characteristics of the subject eye; and

a controller configured to control the subjective measurement optical system and the objective measurement optical system,

wherein the controller is further configured to:

measure a plurality of objective measurement refractive values of the subject eye by the objective measurement optical system at multiple times in a time series at least between a start and an end of an RG test;

monitor the objective measurement refractive values measured in the time series; and

determine that an accommodation intervention has occurred during the RG test when a variation in a lowering direction between the measured objective measurement refractive values exceeds a predetermined threshold.

2 . The ophthalmologic apparatus according to claim 1 ,

wherein the ophthalmologic apparatus is an objective measuring machine that comprises a subjective function and comprises the subjective measurement optical system and the objective measurement optical system, and

wherein the objective measurement optical system comprises a function of simultaneously measuring the objective refractive characteristics of both eyes as the subject eye.

3 . The ophthalmologic apparatus according to claim 1 , wherein the controller is further configured to:

issue an alert or give feedback to eye examination content when the accommodation intervention has been determined.

4 . The ophthalmologic apparatus according to claim 1 ,

wherein in the subjective measurement optical system, an RG chart is used as an optotype in the RG test, the RG chart comprising a red optotype and a green optotype arranged relative to each other.

5 . The ophthalmologic apparatus according to claim 4 , wherein the controller is further configured to

perform a subjective examination comprising the RG test to each eye as the subject eye; and

output a command for a binocular balance test after the subjective examination is completed to both the eyes as the subject eye.

6 . The ophthalmologic apparatus according to claim 5 , wherein the controller is further configured to verify a cause for vagueness of binocular balance based on either a monocular examination of the subject eye with monocular occlusion or a monocular examination of the subject eye with binocular open if the binocular balance is determined to be vague in the binocular balance test with both eyes as the subject eye simultaneously viewing the optotypes.

7 . The ophthalmologic apparatus according to claim 1 , further comprising an examiner controller configured to receive an input operation from an examiner and output a control signal to the controller,

wherein the controller is further configured to

make the objective measurement refractive values into information represented by a two-dimensional coordinates graph which indicates a relationship between an objective measurement value and power of a corrective lens for the subject eye and/or subjective measurement time; and

output a command for displaying the two-dimensional coordinates graph on a display of the examiner controller upon performing the objective monitoring during the RG test.

8 . The ophthalmologic apparatus according to claim 7 , wherein the controller is further configured to output, to the examiner controller, a command for displaying the objective measurement refractive values at predetermined timing including time intervals when performing the objective monitoring during the RG test.

9 . The ophthalmologic apparatus according to claim 8 , wherein the controller is further configured to output, to the examiner controller, a command for displaying the objective measurement refractive values when the spherical power is changed by the corrective lens during the RG test, the objective measurement refractive values-being obtained at a timing at which the spherical power is changed.

10 . The ophthalmologic apparatus according to claim 8 , wherein the controller is further configured to output, to the examiner controller, a command for displaying the objective measurement refractive values when a voice of the examinee who reads an optotype is recognized during the RG test, the objective measurement refractive values being obtained at a timing at which the voice is recognized.

11 . The ophthalmologic apparatus according to claim 1 , wherein the controller is further configured to change a spherical power of a corrective lens as a measure to reduce the accommodative intervention when the accommodation intervention is determined.

12 . The ophthalmologic apparatus according to claim 1 , wherein the controller is further configured to provide an instruction to an examiner as a measure to reduce the accommodative intervention when the accommodation intervention is determined.

13 . The ophthalmologic apparatus according to claim 1 , wherein the objective measurement refractive values are equivalent spherical powers.

14 . The ophthalmologic apparatus according to claim 1 , further comprising an examiner controller configured to receive an input operation from an examiner and output a control signal to the controller, wherein the examiner controller is configured to display a two-dimensional coordinates graph in which a plurality of objective measurement refractive values obtained between the start and the end of the RG test are plotted.

15 . The ophthalmologic apparatus according to claim 14 , wherein the controller is further configured to determine that the accommodative intervention has occurred when the plotted objective measurement refractive values exhibit a variation in a lowering direction that exceeds a predetermined threshold.
