To provide a subjective optometer capable of accurately measuring optical properties of an eye to be examined by correcting an optical aberration.SOLUTION: A subjective optometer is equipped with subjective measuring means for subjectively measuring optical properties of an eye to be examined, including a light projecting optical system for projecting a target light flux to the eye to be examined, a correction optical system arranged in an optical path of the light projecting optical system for changing optical properties of the target light flux, and an optical member for guiding the target light flux corrected by the correction optical system to the eye to be examined. The subjective optometer includes setting means for setting a correction quantity for correcting a third optical aberration component on the basis of a first optical aberration component generated by the subjective measuring means and a second optical aberration component generated by the optical properties of the eye to be examined, and correction means for correcting the third optical aberration component based on the correction quantity.SELECTED DRAWING: Figure 1【課題】 光学収差を補正して、被検眼の光学特性を精度よく測定できる自覚式検眼装置を提供する。【解決手段】 視標光束を被検眼に向けて投影する投光光学系と、投光光学系の光路中に配置され、視標光束の光学特性を変化する矯正光学系と、矯正光学系によって矯正された視標光束を被検眼に導光する光学部材と、を有し、被検眼の光学特性を自覚的に測定する自覚式測定手段を備える自覚式検眼装置であって、自覚式測定手段によって発生する第１光学収差成分と、被検眼の光学特性によって発生する第２光学収差成分と、に基づいた第３光学収差成分を補正するための補正量を設定する設定手段と、補正量に基づいて第３光学収差成分を補正する補正手段と、を備える。【選択図】 図１
