Subjective optometry apparatus

A storage medium that stores a subjective optometry program used in a subjective optometry apparatus that subjectively measures optical characteristics of an examinee's eye and includes a light projecting optical system that projects a target light flux to the examinee's eye, a fixed optical element that guides an image of the target light flux to the examinee's eye so as to have an optically predetermined examination length, and a calibration optical system disposed in an optical path of the light projecting optical system to change the optical characteristics of the examinee's eye,

• the subjective optometry program, when executed by a processor of the subjective optometry apparatus, causing the subjective optometry apparatus to execute:
• a positional information acquiring step of acquiring positional information of the measurement unit that accommodates the light projecting optical system;
• a correction amount setting step of setting a correction amount for correcting a projection magnification of the target light flux projected to the examinee's eye, based on the positional information;
• and
• a correcting step of correcting the projection magnification of the target light flux based on the correction amount set in the correction amount setting step.
