To provide an ocular adjusting function measuring instrument with which the state of an ocular adjusting function is measured more precisely.

The ocular adjusting function measuring instrument is provided with: a right eye refraction detection means and a left eye refraction detection means respectively having a measuring optical system for detecting the refraction variation of the right eye and the left eye; a right eye fixation mark optical system and a left eye fixation mark optical system respectively having a fixation mark which can move in a distance direction with respect to the right eye and the left eye; and an adjusting function measuring means for obtaining the states of the adjusting function of the respective right eye and left eye based on the aging of the refraction detected by the right eye refraction detection means and the left eye refraction detection means at a position obtained by moving the right and left fixation marks by the portion of the same diopter with distant refraction from which adjustment of the right eye and the left eye is respectively removed as reference.
