The present invention relates to emit light across the anterior chamber of the eye of the person to be measured, before the optical measurement for receiving light across the anterior chamber, the structure of the skin around the inner corner of the eye or near the outer corner of the eye just pushed into the orbit compared to, it prevents the exposed areas of the eyeball becomes narrow. An optical measuring apparatus 1 of the present invention is crossed with the first mirror 29 for emitting light across the anterior chamber of the eye 10 of the person to be measured, the anterior chamber is emitted from the first mirror 29 the first and second mirror 31, in a position pushed the inner corner of the eye or near the outer corner of the eye around the skin of the eye 10 in the orbit 17 eyeball 10 is accommodated, inner corner of the eye push section 80 and the light-emitting system for positioning a first mirror 29 for receiving the light comprising a holding portion 50D, and a suppressing eyelid pressing section 70 to the exposed regions of the eye due to the positioning becomes narrow.FIELD 3【課題】被計測者の眼球の前眼房を横切るように光を出射し、前眼房を横切った光を受光する光計測において、目頭周辺または目尻周辺の皮膚を眼窩内に押し込むだけの構成と比較し、前記眼球の露出した領域が狭くなることを抑制する。【解決手段】本発明の光計測装置1は、被計測者の眼球10の前眼房を横切るように光を出射する第1ミラー29と、第1ミラー29から出射され前眼房を横切った光を受光する第2ミラー31と、眼球10の目頭周辺または目尻周辺の皮膚を眼球10が収容された眼窩17内に押し込んだ位置に、第1ミラー29を位置決めする目頭押込部80および発光系保持部50Dと、この位置決めにともない眼球の露出した領域が狭くなることを抑制する瞼抑え部70とを備える。【選択図】図3
