Abstract

An ophthalmologic apparatus includes a visual-target presenting portion (41) that is configured to present visual targets (8) to left and right subject eyes (EL, ER), respectively; and an objective measurement optical system (6, 7) that is configured to objectively measure eye characteristics of the left and right subject eyes (EL, ER), respectively. The visual-target presenting portion (41) is configured to present the visual targets (8) while changing a convergence position (R, R1, R2), where two lines of sight (SL1, SR1, SL2, SR2) from positions of the left and right subject eyes (EL, ER) intersect, with pinhole plates (50) respectively disposed at positions conjugate with pupils of the left and right subject eyes (EL, ER). The objective measurement optical system (6, 7) is configured to obtain the objective refractive values of the left and right subject eyes (EL, ER), respectively, under a condition where the pinhole plates (50) are respectively disposed by the visual-target presenting portion (41) and the visual targets (8) presented at the convergence position (R, R1, R2) are binocularly fused.
