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.
