Abstract: Disclosed is a myopia progression analysis device including: an eye axial length acquisition section that acquires an eye axial length of an eye of a subject; a reference value acquisition section that acquires a numerical value related to a physical characteristic of the subject other than the eye axial length as a reference value; a relative eye axial length calculator that calculates a relative eye axial length through relativization of the eye axial length acquired by the eye axial length acquisition section using the reference value acquired by the reference value acquisition section; a population information acquisition section that acquires population information which is a set of information about relative eye axial lengths of a plurality of comparison targets to be compared with the subject; and a relative position information calculator.
