Eye examination apparatus, method for manufacturing spectacle lens, spectacle lens, method for manufacturing multifocal eyeglasses, and multifocal eyeglasses

A method for manufacturing eyeglass lenses comprising:

• (a) acquiring an accommodation power that is determined from a difference between a near point and a distant point of an examined eye;
• (b) calculating an integrated value of the accommodation power acquired in (a) and a correction coefficient;
• (c) placing a vision target to a corrected accommodation position corresponding to the integrated value calculated in (b) and measuring an accommodative microfluctuation of an eye accommodation function based on a frequency of appearance of a high frequency component representative of ciliary body accommodative microfluctuation;
• (d) analyzing a result of the accommodative microfluctuation measurement in (c) and determining whether the examined eye is in a tense state, a proper state, or a relaxed state;
• (e) performing a remeasurement of accommodative microfluctuation in which the vision target is corrected to lie on a side of the distant point from the corrected accommodation position if it is determined that the examined eye is in a tense state in (d), and performing a remeasurement of accommodative microfluctuation in which the vision target is corrected to lie on a side of the near point from the corrected accommodation position if it is determined that the examined eye is in a relaxed state in (d);
• (f) analyzing a result of the remeasurement obtained in (e) and repeating (d) and (e) until the examined eye is determined to be in a proper state;
• (g) calculating an additional power based on a position of the vision target determined to be in a proper state in (d);
• (h) calculating an inset amount based on a refractive power of the distant point measured in (a);
• and
• (i) arranging a near vision center of a near vision refraction portion of a lens of multifocal eyeglasses corresponding to the additional power calculated in (g) based on the inset amount calculated in (h).
