Abstract:
1. An eye examination apparatus comprising: an accommodation power acquisition unit configured to acquire an accommodation power which is determined from a difference between a near point and a distant point of an examined eye; a corrected accommodation power calculation unit configured to calculate an integrated value of the accommodation power acquired by the accommodation power acquisition unit and a correction coefficient; a drive unit configured to drive a vision target in a direction of an optical axis of the examined eye; and an accommodative microfluctuation measurement unit configured to control the drive unit to cause the vision target to be arranged onto a corrected accommodation position corresponding to the integrated value calculated by the corrected accommodation power calculation unit, such that the accommodative microfluctuation measurement unit measures an eye accommodation function based on a frequency of appearance of a high frequency component representative of ciliary body accommodative microfluctuation.
