Eye examination apparatus, method for manufacturing spectacle lens, spectacle lens, method for manufacturing multifocal eyeglasses, and multifocal eyeglasses
摘要:
An eye examination apparatus includes an accommodation power acquisition unit, a corrected accommodation power calculation unit, a drive unit and an accommodative microfluctuation measurement unit. The accommodation power acquisition unit acquires an accommodation power which is determined from a difference between a near point and a distant point of an examined eye. The corrected accommodation power calculation unit calculates an integrated value of the accommodation power and a correction coefficient. The drive unit drives a vision target in a direction of an optical axis of the examined eye. The accommodative microfluctuation measurement unit controls the drive unit to cause the vision target to be arranged onto a corrected accommodation position corresponding to the integrated value, 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.
