    Abstract: The invention relates to an optometry device (100) for testing an individual's eye (1), comprising a refraction test unit (10) having a vision correction optical system (13) for providing different vision correction power values; and a display unit (20) comprising a control unit (28, 29) controlling a projection optical system (20A, 20B) adapted to produce from a scene picture and from a visual test picture including a functional zone, respectively: - along a scene optical path of said projection optical system a scene image (SCN) at a scene distance (D2) from the individual's eye; and - along a visual test optical path of the projection optical system, a visual test image (OPT) at a visual test distance (D1) from the individual's eye smaller than or equal to said scene distance of projection, said visual test image being superimposed at least partially with said scene image. According to the invention, said control unit is configured to define in the scene picture at least one scene zone implying transparency (50) for the corresponding scene image and in the superimposition area between the visual test image and the scene image, allowing the individual's eye to observe the functional zone of the visual test image without contrast decrease, at the visual test distance.
