The patent filed by EssilorLuxottica SA describes an optometry device for testing an individual's eyes, consisting of a refraction test unit with a vision correction optical system and a display unit with a projection optical system. This system projects a scene image and a visual test image, superimposed with a functional zone, at different distances from the individual's eye. The control unit ensures transparency in specific zones of the scene picture, allowing the individual to observe the functional zone of the visual test image without contrast decrease at the visual test distance.
Additionally, the patent includes claims related to the configuration of the scene picture, colorimetry distribution, modifiability of visual test distance, and the use of a flexible mask and rigid junction part. The patent also covers a set of pictures for the optometry device, defining the scene and visual test images, as well as a computer program product for displaying these images. Furthermore, a display unit is described, including the projection optical system, control unit, and computer program product for controlling the display of images for optometry testing. Overall, the patent focuses on enhancing the testing process by providing precise control over the visual stimuli presented to the individual's eye during optometry examinations.
