Abstract: The invention relates to an optometry device for testing an individual's eye, comprising a refraction test unit (10) having an optical system for providing different vision correction powers close to the eye of the individual, and a display unit (20) adapted to produce a visual test image for the individual's eye, said visual test image being visible through an exit aperture (10A) of said test unit of the optometry device, this display unit comprising: - a screen (21) adapted to display a test picture used in producing said visual test image and - at least one optical element (30) having an optical power. According to the invention, said optical element presents an active state in which it exhibits a non zero refraction power placed on an optical path of the light emitted by said screen and exiting the device through said exit aperture, and an inactive state in which it introduces no refractive power on said optical path, in order for the visual test image to be produced at a variable distance from said exit aperture.
