Abstract: An ophthalmologic apparatus includes a subjective measurement optical system configured to measure a subjective refractive value of a subject eye; an objective measurement optical system configured to measure objective refractive characteristics of the subject eye; and a controller configured to control the subjective measurement optical system and the objective measurement optical system. The controller is further configured to perform measurement of the objective refractive characteristics of the subject eye by the objective measurement optical system and perform objective monitoring to monitor objective measurement information obtained by the measurement of the objective refractive characteristics during a weakest power test in which a weakest point is being obtained by the subjective measurement optical system, a maximum visual acuity value or a set predetermined visual acuity value being readable from the weakest point.

Abstract: An ophthalmologic apparatus includes an objective measurement optical system that is configured to objectively measure eye characteristics of a subject eye; an optotype projection system that is configured to present a fixation target to the subject eye at a predetermined presentation position and apply fog to the subject eye; and a controller that is configured to control the objective measurement optical system and optotype projection system. The controller is further configured to objectively measure the eye characteristics over time by changing a presentation position of the fixation target from the predetermined presentation position in a direction to increase an amount of fog and presenting the fixation target.

Abstract: An ophthalmologic apparatus includes a subjective measurement optical system configured to measure a subjective refractive value of a subject eye, an objective measurement optical system configured to measure objective refractive characteristics of the subject eye, and a controller configured to control the subjective measurement optical system and the objective measurement optical system. The controller is further configured to measure the objective refractive characteristics of the subject eye by the objective measurement optical system and perform objective monitoring to monitor objective measurement information obtained by the measurement of the objective refractive characteristics during an RG test for checking whether or not corrected power is overcorrected or undercorrected by the subjective measurement optical system.
