摘要： An ophthalmic apparatus includes an image acquisition unit (159) configured to acquire an anterior segment image (E') of a subject eye (E), an optotype projection system (140) configured to present an optotype to the subject eye (E) in at least two presentation positions different from each other, and a line-of-sight direction detection unit (26) configured to extract a feature point from the anterior segment image (E') that has been acquired by the image acquisition unit (159) when the optotype has been presented in each of the at least two presentation positions, detect positional information on the anterior segment image (E') of the feature point that has been extracted, and detect a line-of-sight direction of the subject eye (E) on a basis of the positional information.

摘要： An ophthalmologic apparatus (1) includes a subjective measurement optical system (44) configured to measure a subjective refractive value of a subject eye (E); an objective measurement optical system configured to measure objective refractive characteristics of the subject eye (E); and a controller (40) configured to control the subjective measurement optical system (44) and the objective measurement optical system. The controller (40) is further configured to measure the objective refractive characteristics of the subject eye (E) 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 (44).

摘要： An ophthalmologic apparatus (1) includes an objective measurement optical system that is configured to objectively measure eye characteristics of a subject eye (E); an optotype projection system (42) that is configured to present a fixation target to the subject eye (E) at a predetermined presentation position and apply fog to the subject eye (E); and a controller (40) that is configured to control the objective measurement optical system and optotype projection system (42). The controller (40) 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.
