PROBLEM TO BE SOLVED: To correctly measure states of inflection in different states of pupil diameters.
SOLUTION: There is provided an ophthalmologic device including a visual fixing optical system 80 which lights on a subjects eye E, a light-receiving optical system 30 which can measure the distribution of optical characteristics within the pupil diameters of the subjects eye E, a pupil diameter-measuring means which measures the pupil diameters of the subjects eye E by download of measurement results from the light-receiving optical system 30, and a display which indicates the measurement results. The visual fixing optical system 80 has a function that can light with night-brightness and day-brightness to the subjects eye E. The light-receiving optical system 30 can continuously measure the respective pupil diameters of the subjects eye E when lighted with night-brightness and when lighted with day-brightness multiple times. The pupil diameter-measuring means calculates the maximum size of multiple pupil diameters of the subjects eye E at night-brightness and the minimum size of those at day-brightness from a distribution of the pupil diameters of the subjects eye E determined by the light-receiving optical system 30.
