    • A subjective optomater that is capable of measuring accommodation ability of an eye while reducing the influence of accommodative convergence is provided. A subjective optometer includes: a visual target that is presented to an eye through a measuring optical axis; a measuring optical system that includes a spherical lens capable of changing spherical power on the measuring optical axis; a spherical power changer that changes the spherical power of the spherical lens; and an optical axis deflector that deflects the measuring optical axis so as to align the measuring optical axis with a visual axis of the eye, wherein accommodation ability is measured based on the spherical power of the spherical lens in a state in which the measuring optical axis is deflected by the optical axis deflector.
    • 提供了能够测量眼睛的适应能力同时减少调节收敛的影响的主观视觉仪。 主观验光仪包括:通过测量光轴呈现给眼睛的视觉目标; 测量光学系统,其包括能够改变测量光轴上的球面光焦度的球面透镜; 改变球面透镜的球面光焦度的球面变换器; 以及偏转测量光轴以使测量光轴与眼睛的视轴对准的光轴偏转器,其中,在测量光轴的状态下,基于球面透镜的球面光焦度来测量适应能力 被光轴偏转器偏转。
