PROBLEM TO BE SOLVED: To provide a measuring device which reduces positional deviation of optical emission means and receiving means associated with opening eyelids with eyelid opening means in comparison with the case where just the eyelid opening means is provided.SOLUTION: The invented optical measuring device 1 includes: an eyelid hold-down part 70 which contacts the skin around a measured persons eye ball 10 and maintains the measured persons upper eyelid 18 and lower eyelid 19 opening a light-emitting system 21 which emits light to the anterior chamber of the eye ball 10 while the upper eyelid 18 and the lower eyelid 19 are opened with the eyelid hold-down part 70 and a light-receiving system 23 which receives the light emitted from the light-emitting system 21 and crossing the anterior chamber while the upper eyelid 18 and the lower eyelid 19 are opened with the eyelid hold-down part 70.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】単に開瞼手段を設ける場合と比べ、開瞼手段が瞼を開かせることにともなう、出射手段および受光手段の位置ずれを低減した計測装置を提供する。【解決手段】本発明の光計測装置1は、被計測者の眼球10周辺の皮膚に接触して被計測者の上眼瞼18および下眼瞼19を開いた状態に維持する瞼抑え部70と、瞼抑え部70によって上眼瞼18および下眼瞼19が開かれた状態において、眼球10の前眼房に光を出射する発光系21と、瞼抑え部70によって上眼瞼18および下眼瞼19が開かれた状態において、発光系21から出射され前眼房を横切った光を受光する受光系23とを備える。【選択図】図4
