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.
