Eye gaze vector detection device, visual function inspection device, visual function training device and method

摘要

An object of the present invention is to more accurately detect a gaze vector along a subject's gaze direction. According to one embodiment, a gaze vector detection device according to an embodiment includes a plurality of IR illumination devices that respectively irradiate examination light to an eyeball of a subject, an imaging device that picks up a reflection image of the examination light by the eyeball, An optical axis vector calculation unit that calculates an optical axis vector based on the position of the reflected image when viewing an object, the spatial coordinates of the visible object, and the spatial coordinates of the corneal curvature center assuming the cornea of the subject .
