PROBLEM TO BE SOLVED: To provide a subjective optometer, and an optometry system, capable of reflecting astigmatism examination in a prescription of glasses or the like.SOLUTION: A subjective optometer includes: a spherical diopter power generation part including lenses and generating a spherical diopter power an astigmatic element generation part disposed on an optical system and having two cylindrical lenses and a control part. The control part calculates composite correction values composed according to a cross-cylinder diopter power and cross-cylinder axial angles 45°, 90°, 135°, 180° for astigmatism examination to correction values in a state that the lenses are disposed in correction positions based on the correction values of the spherical diopter power, an astigmatic diopter power, and an astigmatic axis (S20), disposes the lenses in composite correction positions based on the composite correction values by controlling the spherical diopter power generation part and the astigmatic element generation part (S30), receives an optometry result (S40), and calculates new correction values in which the correction values are corrected (S50).COPYRIGHT: (C)2015,JPO&INPIT【課題】乱視検査を、眼鏡等の処方に反映できる自覚式検眼装置、検眼システムを提供する。【解決手段】自覚式検眼装置は、レンズを備え、球面度数を生成する球面度数生成部と、光学系上に配置され2つの円柱レンズを有する乱視要素生成部と、制御部とを備え、制御部は、球面度数、乱視度数、乱視軸の矯正値に基づいた矯正位置にレンズを配置している状態で、矯正値に対して、乱視検査のためのクロスシリンダ度数及びクロスシリンダの軸角度45°、90°、135°、180°に応じて合成した合成矯正値を算出しS20、合成矯正値に基づいた合成矯正位置に、レンズを、球面度数生成部及び乱視要素生成部を制御して配置しS30、検眼結果を受け付けてS40、矯正値を補正した新矯正値を算出するS50。【選択図】図4
