摘要:
A visual sense examination device includes: a beam source that emits a visible beam and an invisible beam; a visible beam optical system that includes a first scanner scanning the visible beam; an invisible beam optical system that includes a second scanner scanning the invisible beam; a detector that detects the invisible beam reflected by a retina of a subject; a controller that performs a first control; a synthesizer that synthesizes the visible beam scanned by the first scanner and the invisible beam scanned by the second scanner; and wherein scanning angles of the visible beam by the first scanner and the invisible beam by the second scanner are substantially the same, and projectable ranges of the visible beam scanned by the first scanner and the invisible light scanned by the second scanner are substantially the same on the retina of the subject.
