Provided are an ophthalmologic apparatus used for determining an optimum addition power closer to a natural vision state, and a method of operating the ophthalmologic apparatus. An optotype presenting section for presenting a common optotype visually recognized by both eyes of the subject's eye, and a presenting distance of the optotype presented by the optotype presenting section to a predetermined near vision from a predetermined far vision distance. A presentation distance changing unit for changing to a visual distance, an eye characteristic acquiring unit for objectively acquiring the optical characteristics of the subject's eye, an additional power adding unit for adding additional power to both eyes, and an additional power adding unit. A control unit is provided for executing a change of a presentation distance by a presentation distance changing unit and a continuous acquisition of an optical characteristic by an eye characteristic acquisition unit in a state in which an arbitrary degree of addition is added to the eye.より自然視状態に近い最適な加入度数の決定に用いられる眼科装置、及び眼科装置の作動方法を提供する。被検眼の両眼で視認される共通の視標を呈示する視標呈示部と、視標呈示部により呈示される視標の呈示距離を、予め定めた遠見視の距離から予め定めた近見視の距離へ変更する呈示距離変更部と、被検眼の光学特性を他覚的に取得する眼特性取得部と、両眼に加入度数を付加する加入度数付加部と、加入度数付加部により両眼に任意の加入度を付加した状態で、呈示距離変更部による呈示距離の変更と、眼特性取得部による光学特性の連続的な取得と、を実行させる制御部と、を備える。
