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.

Visual sense examination device

Provided is a vision test device including: a projection unitthat projects an image on a retina of a subject with use of a laser beamby two-dimensionally scanning the laser beam; a beam diameter setting unit that sets a beam diameter of the laser beam; and a numerical aperture setting unit that sets a numerical aperture of the laser beam, wherein the projection unit projects, on the retina, a test image for measuring visual information of the subject with use of a laser beam having the set beam diameter and the set numerical aperture.

Vision test device

A visual field/visual acuity examination system includes a retinal projection head-mounted display; and a terminal device. The terminal device outputs examination image data to the retinal projection head-mounted display; displays an image on a display; and generates an examination image based on the examination image data and display the examination image on the display. The retinal projection head-mounted display inputs the examination image data from the terminal device; generates an image light beam based on the input examination image data and control emission of the image light beam from a light source; causes a scanning minor to scan the image light beam to generate an examination image light beam; and projects the examination image light beam as the examination image on a retina of an eyeball of a test subject after converging the examination image light beam in a vicinity of a pupil of the eyeball.
