PROBLEM TO BE SOLVED: To provide an optical measurement apparatus for an eyeball, etc. which suppresses the irradiation of an unintended portion of an eyeball with measurement light, compared with when the direction of the eyeball is not detected.SOLUTION: An optical measurement apparatus 1 for an eyeball 10 comprises: a light emitting system 20A for emitting light in such a manner that the light passes across an eyeball 10 of a subject a light receiving system 20B for receiving light transmitted through the eyeball 10 a detector 70 for detecting a direction of the eyeball 10 and a controller 40 for control in such a manner that the light emitting system 20A starts emitting light at an intensity for use in measurement or the light emitting system 20A raises the intensity of light emitted therefrom to a level for use in measurement, when the direction of the eyeball 10 detected by the detector 70 is in a predetermined range.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】眼球の向きを検知しない場合に比べ、計測に用いる光が眼球内の意図しない部位に照射されることを抑制した眼球の光計測装置などを提供する。【解決手段】眼球10の光計測装置1は、被計測者の眼球10を横切るように光を出射する発光系20Aと、眼球10を透過した光を受光する受光系20Bと、眼球10の向きを検知する検知部70と、検知部70により検知された眼球10の向きが予め定められた範囲内にある場合に、発光系20Aから計測に用いる強度で光の出射を開始する、又は、発光系20Aが出射する光を計測に用いる強度に上げるように制御する制御部40と、を備える。【選択図】図1
