Abstract: A retinal projection device includes: a projector module including a light source that emits laser light and a movable mirror that performs scanning with the laser light; a reflector that projects an image onto a retina of a user wearing the near eye wearable device by reflecting the laser light having passed through the movable mirror and irradiating the retina with reflected light; and a controller that determines an irradiation range of the reflector to be irradiated with the laser light in accordance with a position of a pupil of the user and controls the projector module to irradiate the irradiation range with the laser light. The reflector includes a plurality of unit regions provided along a surface of a lens of the near eye wearable device, and the surface faces an eyeball of the user. The irradiation range is a part of the plurality of unit regions.
