PROBLEM TO BE SOLVED: To provide a subjective optometer capable of measuring an accommodation ability of a subjects eye, with an influence of accommodation convergence reduced.SOLUTION: The subjective optometer comprises: a measurement optical system including a target to be presented to a subjects eye on a measurement optical axis, and a spherical lens, the spherical diopter of which is changeable in the measurement optical axis a spherical diopter change unit that changes the spherical diopter of the spherical lens and an optical axis deflection unit that deflects the measurement optical axis so as to match a visual axis of the subjects eye. The accommodation ability is measured based on the spherical diopter of the spherical lens in a state where the measurement optical axis is deflected by the optical axis deflection unit.COPYRIGHT: (C)2014,JPO&INPIT【課題】被検眼の調節力を、調節性輻輳による影響を低減して測定することが可能な自覚式検眼装置を提供すること。【解決手段】自覚式検眼装置は、測定光軸において、被検眼に呈示される視標と、測定光軸における球面度数が変更可能な球面レンズを備える測定光学系と、前記球面レンズの球面度数を変更する球面度数変更部と、測定光軸を、被検眼の視軸に合致するように偏向する光軸偏向部とを有し、前記光軸偏向部によって測定光軸が偏向された状態における前記球面レンズの球面度数に基づいて調節力を測定する。【選択図】図1
