Original Abstract Submitted
A line-of-sight detection device according to the present invention includes: an eyepiece lens; an image sensor disposed on an edge of the eyepiece lens and configured to capture an image of an eye facing the eyepiece lens; a plurality of first light sources disposed along the edge of the eyepiece lens; a plurality of second light sources disposed along the edge of the eyepiece lens, wherein on a plane that intersects vertically with an optical axis of the eyepiece lens, a distance from a position of each of the plurality of second light sources projected on the plane to the optical axis is longer than a distance from a position of each of the plurality of first light sources projected on the plane to the optical axis.
