    • An optometric apparatus for examining refractive power of an examinee's eye subjectively, capable of performing highly-precise examination. The apparatus has a test window through which a presented optotype is seen, a first spherical-power applying unit which applies spherical power to the eye by changing a combination of spherical lenses in the window, a cylindrical-power applying unit which applies cylindrical power to the eye by changing a relative angle of a cylindrical axis of cylindrical lenses in the window, a second spherical-power applying unit including a spherical lens for correction, an instruction unit which instructs examination spherical and cylindrical power, a power-determining unit which determines power applied by the power-applying units so that a difference between the instructed examination power, and resultant spherical and cylindrical power through conversion for a spectacles wearing reference position falls within a predetermined permissible difference, and a control unit which controls driving of the power-applying units.
