Zusammenfassung:A subjective eye examination device is provided with a subjective measurement unit and an objective measurement unit, the subjective measurement unit subjectively measures the optical characteristics of the eye to be examined and has a light projection optical system that projects a target light beam onto the eye to be examined; a correction optical system that has a right-eye correction optical system and a left-eye correction optical system provided in a pair at the left and right sides, and is disposed in the optical path of the projection optical system to change the optical characteristics of the target luminous flux; and an optical member which is common to a right-eye optical path including the right-eye correction optical system and a left-eye optical path including the left-eye correction optical system, and guides the optotype luminous flux corrected by the correction optical system to the eye to be examined. The objective measurement unit has a measurement optical system that emits measurement ligh
