EYE REFRACTION MEASURING APPARATUS

To provide an ophthalmologic apparatus capable of measuring detailed refraction of a subject eye.SOLUTION: The present invention relates to an eye refraction measuring apparatus for objectively measuring the refraction of a subject eye, the refraction measuring apparatus including: fixation target projection means for projecting a fixation target onto the fundus of the subject eye; and objective measuring means comprising a light projection optical system for projecting a measurement light flux onto the fundus of the subject eye and a light reception optical system for receiving, by a detector, a fundus-reflected light flux that is the measurement light flux reflexed at the fundus. In the light reception optical system, the first measurement axis for the fundus-reflected light flux received by the detector is set off-axis with respect to the fixation target axis for a target light flux projected by the fixation target projection means. The light projection optical system projects a measurement light flux onto the fundus and the light reception optical system receives a fundus-reflected light flux, so that the eye refraction of the fundus peripheral part is measured with respect to the visual line of the subject eye.SELECTED DRAWING: Figure 1 【課題】被検眼の詳細な眼屈折力を測定できる眼科装置を提供する。【解決手段】 被検眼に固視標を投影する固視標投影手段と、被検眼の眼底に測定光束を投光する投光光学系と、眼底にて測定光束が反射された眼底反射光束を検出器によって受光する受光光学系と、を有する他覚式測定手段と、を備え、被検眼の眼屈折力を他覚的に測定する眼屈折力測定装置であって、受光光学系において、検出器に受光される眼底反射光束の第１測定軸は、固視標投影手段によって投影される視標光束の固視標軸に対して軸外となるように設定され、投光光学系が測定光束を前記眼底へ投光し、受光光学系が眼底反射光束を受光することによって、被検眼の視軸に対する眼底周辺部の眼屈折力を測定する。【選択図】 図１
