Problem to be solved: to provide a visual function inspection apparatus capable of performing good visual inspection under dark adaptation conditions.The visual function inspection apparatus irradiates the stimulated position of the eye fundus er with the stimulated light and the background light by the inspection optical system, and acquires the reaction of the examinee by the stimulating light based on the operation of the response button 7C by the control portion 80. The control unit 80 controls at least the irradiation position of the stimulated light from the inspection optical system to the inspection site.The test optical system irradiates the background light with the brightness corresponding to dark adaptation, and has a lower limit on the longer wavelength side than the sensitivity peak (420 nm) of the blue cone cell, has an upper limit on the shorter wavelength side than the sensitivity peak (534 nm) of the green cone cell, and at least the sensitivity peak of the rod cell Stimulated light and background light are irradiated in the wavelength band including 98 nm.Diagram【課題】暗順応条件下での視機能検査を良好に行うことができる視機能検査装置を提供する。【解決手段】視機能検査装置は、検査光学系によって、眼底Erの検査部位へ刺激光と、背景光とを照射し、制御部80によって、刺激光による被検者の反応を応答ボタン7cの操作に基づいて取得する。また、制御部80は、検査光学系から検査部位への刺激光の照射位置を少なくとも制御する。検査光学系は、背景光を暗順応に対応する輝度で照射すると共に、青色錐体細胞の感度ピーク(420nm)よりも長波長側に下限を持ち、緑色錐体細胞の感度ピーク(534nm)よりも短波長側に上限を持ち、且つ、少なくとも杆体細胞の感度ピーク(498nm)を含んだ波長帯で、刺激光および背景光を照射する。【選択図】図8
