It is a nical object to provide a visual function measuring device capable of appropriately confirming the effects of prescription eyeglasses and the like. A visual function measuring device according to the present disclosure includes a measurement optical system that projects measurement light on a fundus of an eye to be examined and measures eye refractive power of the eye to be examined based on reflected light from the fundus, A fixation target presenting optical system capable of changing a presenting position of a fixation target to be inspected with respect to the eye to be examined, correction means for correcting the eye refractive power of the eye to be examined by driving the correction optical system, And control means for calculating an adjustment tension parameter of the eye to be examined from a temporal change of the eye refracting power measured by the examinee, wherein the control means acquires frequency information of eyeglasses worn by the examinee, Changing the correction state of the eye to be examined by controlling the correction means based on the information, and calculating the adjustment tension parameter of the eye to be examined in the correction state based on the frequency information.処方眼鏡等の効果を適切に確認できる視機能測定装置を提供することを技術課題とする。本開示の視機能測定装置は、被検眼の眼底に測定光を投光し、前記眼底からの反射光に基づいて前記被検眼の眼屈折力を測定する測定光学系と、前記被検眼に呈示する固視標の呈示位置を前記被検眼に対して変更可能な固視標呈示光学系と、矯正光学系を駆動させ、前記被検眼の眼屈折力を矯正する矯正手段と、前記測定光学系によって測定される前記眼屈折力の経時変化から前記被検眼の調節緊張パラメータを演算する制御手段と、を備え、前記制御手段は、被検者が装用する眼鏡の度数情報を取得し、前記度数情報に基づいて前記矯正手段を制御することによって被検眼の矯正状態を変更し、前記度数情報に基づく前記矯正状態において前記被検眼の調節緊張パラメータを演算することを特徴とする。
