Provided is a technique capable of quantitatively and easily inspecting at least one of the type and degree of color blindness at a clinical site. A light source unit configured to output light to be visually recognized by a subject and to be able to cope with variable wavelength of the light, and a wavelength control unit that performs variable control of the wavelength of light output from the light source unit. 31, based on the operation unit 20 to which information on the visual aspect of the subject is input by the operation of the subject, the control content by the wavelength control unit 31 and the input information in the operation unit 20, The color vision inspection apparatus 1 includes the measurement control unit 32 that specifies at least one of the wavelength discrimination threshold value or the relative visibility of the eye of the subject. [Selection] Figure 1【課題】色覚異常の型と程度の少なくとも一方を定量的に、かつ、臨床現場で容易に検査することができる技術を提供する。【解決手段】被検者に視認させる光を出力するとともに当該光の波長可変に対応可能に構成された光源部１２と、前記光源部１２が出力する光の波長の可変制御を行う波長制御部３１と、前記被検者の操作により当該被検者の視認態様に関する情報が入力される操作部２０と、前記波長制御部３１による制御内容および前記操作部２０での入力情報に基づいて、前記被検者の眼の波長弁別閾値または比視感度の少なくとも一方を特定する測定制御部３２と、を備えて色覚検査装置１を構成する。【選択図】図１
