PROBLEM TO BE SOLVED: To provide a subjective optometric apparatus capable of easily examining a vision function with a simple configuration without requiring complex control.SOLUTION: A subjective optometric apparatus for subjectively measuring optical characteristics of an eye to be examined includes: a light projecting optical system 30 for projecting a target light beam to the eye to be examined and projecting a target onto the eye to be examined； a correction optical system 60 arranged in an optical path of the light projecting optical system for changing optical characteristics of the target light beam； and an optical member for guiding the target light beam corrected by the correction optical system to the eye to be examined. The subjective optometric apparatus includes optical deflection means for deflecting the target light beam by rotationally driving the optical deflection member, which includes an optical deflection member, which is a member different from the correction optical system and is provided in a right and left pair, and driving means for rotationally driving the optical deflection member, setting means for setting prism information, and control means for controlling the optical deflection means based on the prism information set by the setting means, and deflecting the target light beam.SELECTED DRAWING: Figure 2【課題】複雑な制御を必要とせず、簡易的な構成で容易に視機能の検査を行う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光して視標を被検眼に投影する投光光学系３０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６０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検眼装置であって、矯正光学系と異なる部材であって、左右一対にそれぞれ設けられた光偏向部材と、光偏向部材を回転駆動するための駆動手段と、を有し、光偏向部材を回転駆動させることで視標光束を偏向可能とする光偏向手段と、プリズム情報を設定する設定手段と、設定手段によって設定されたプリズム情報に基づいて、光偏向手段を制御して、視標光束を偏向する制御手段と、を備える。【選択図】図２
