Abstract: An apparatus for determining the diameter of an ophthalmic compensation lens to be mounted onto a spectacle frame, or for controlling the mounting of an ophthalmic compensation lens onto the frame includes: an electronic tablet having a screen; a spectacle frame support having an opening and being suitable for holding the glasses frame in a predetermined position, one surface of the spectacle frame being placed near the surface of the screen; elements for storing at least one graphic image including at least one graphic reference mark associated with the ophthalmic compensation lens and/or with the patient who is to wear the ophthalmic compensation lens mounted onto the frame; elements intended for processing the image and capable of generating a projected image; elements for displaying the projected image onto the screen; and elements for aligning the frame with regards to the projected image displayed on the screen.

Abstract: A method of visual testing of an individual (10) includes the steps of: a) placing the individual at a predetermined observation distance (D1) from a display surface (21) at which the individual observes, with a natural head carriage, the display surface; b) displaying, on the display surface, a visual test including at least one test image (22) in a visual field of the individual; and c) determining, on the display surface, a boundary (23) of zones of optimal/degraded vision of the test image by the individual in the configuration resulting from steps a) and b), the boundary delimiting respectively a zone of optimal vision (23A) and a zone of degraded vision (23B) of the visual field, for which zones the individual indicates that he sees the test image of the visual test in an optimal manner, respectively in a degraded manner.

Abstract: A method for determining at least one optical design parameter for a progressive ophthalmic lens intended to be fitted in a frame of a wearer, depending on the wearer's visual behaviour, includes: a) placing the wearer in a situation in which he carries out a visual task at a first working distance; b) during this task, determining at least two gaze directions of the wearer at this first working distance in a frame of reference of the wearer's head; c) determining a relative position of a surface related to the frame or to an ophthalmic lens intended to be fitted in the frame; d) determining for each gaze direction at the first working distance the intersection between this gaze direction and the surface so as to establish a map of these points of intersection on this surface; and e) deducing the sought-after optical design parameter from this map.
