A method for determining at least one value of a customization parameter for a visual compensation device includes the following steps: a) a user (1) equipped with an electronic terminal (2) captures at least one image or video sequence; b) telecommunicating the at least one image to a remote-support center (22); c) processing the at least one image in order to derive therefrom an instruction to correct or validate the captured image or video sequence; d) telecommunicating the correction or validation instruction from the remote-assistance center (22) to the terminal (2) of the user (1); e) displaying or emitting an audio or video message using the terminal; f) repeating the preceding steps until a validated image or video sequence is obtained; g) determining a value of the at least one customization parameter.
摘要:
A method and an associated system for ordering a spectacle lens by a wearer (1), said method involving steps of: selecting (S1) a spectacle frame by the wearer (1); capturing (S2) a picture showing partially a face of said wearer (1) wearing the selected spectacle frame, at a picture capturing side (10) so as a position of said spectacle frame with respect to the wearer face is extractable from said picture; obtaining (S3.1) a three dimensional shape of the selected frame at said picture processing side (20); processing (S3) said picture for obtaining the position of said spectacle frame with respect to the wearer face at said picture processing side (20); and ordering (S6) to a lens manufacturing side (40) spectacle lens complying with said frame shape, said extracted frame position, and wearer data, wherein said wearer data comprises at least a prescription for the wearer (1).

The invention relates to a referencing device (1, 100) intended to be fixed to an eyeglass frame in order to spatially reference said frame, said device (1, 100) having a transverse bar (2, 102), a central extension (5), two lateral markers (3) and a central marker (4), each marker (3, 4) consisting of a light area (12) and a darker area (11). The main characteristic of a clip according to the invention is that it comprises at least one mobile fastening member (7, 8) which is able to move along at least one slide (9, 10) of the bar (2, 102).
摘要:
A quality control method for optometric measurements includes the following steps: (a) recording, via computer, a first record (14) that includes at least one first value of a first identifier (12), enabling identification of a glasses wearer (1), and at least one other value of another identifier (13) enabling identification of an optometric apparatus (15) on a first optometric measuring site (10); (b) carrying out at least one optometric measurement (16) of the wearer; (c) sending, to a second site (20), a digital measurement data set (18) including the optometric measurement result from step (b), the digital data set being linked, via computer, to the first record; and (d) digitally processing the optometric measurement result from the first record (14) on the basis of a digital data reference system (45) and the values of the respective identifiers of the glasses wearer and the optometric apparatus of the first record.
摘要:
An apparatus for implementing a method for determining the dominant eye of a spectacle wearer (1), includes a target (2), an element (3, 4) for occulting at least one eye, and a sighting device (5, 50) equipped with an optical window (6). The principal feature of the apparatus is that the sighting device (5, 50) includes an electronic sensor making it possible to identify the direction of movement of the sighting device (5, 50), during the method during various steps of viewing the target (2).
摘要:
A method for fitting an actual predetermined glasses frame, selected by a given wearer, for use thereof by the wearer, includes the following steps: the head of the wearer is at least partially modelled, in at least one reference system, with at least one model of part of the nose and one model of part of the ears; simulating the positioning of the frame on the head of the wearer is carried out, in the model of the head of the wearer, by placing the corresponding areas of the frame, or a model of the latter, one over the other; and on the basis of placing these one over the other, the necessary change in shape of the actual predetermined frame is determined in order to achieve a fitting of the frame on the head of the wearer in accordance with at least one predetermined fitting criterion.
摘要:
The invention relates to a method for measuring the geometric morphometric parameters of a person wearing glasses (21), said method implementing an independent computing device (1, 10) comprising a screen, a target (8, 18), a compact image acquisition system (7, 17) which is provided with a means of determining the inclination thereof, said system (7, 17) being connected to said screen, and a computer for controlling the image acquisition system (7, 17) and processing the images obtained. The main feature of a measuring method according to the invention is that it comprises a step in which the person observes the target (8, 18) placed in a position known to the image acquisition system (7, 17), by rolling his or her head in an upward direction while keeping his or her eyes fixed on the target (8, 18).
摘要:
Disclosed is a method for evaluating an index of exposure to ultraviolet radiation of an eye of a wearer equipped with spectacles including at least one eyeglass, including the following steps: —determining the area of a portion of the back face of the eyeglass, which portion is directly exposed to exterior radiation when the wearer is wearing the spectacles; —determining a value representative of the exposure to ultraviolet radiation of at least one environment frequented by the wearer; and —determining the index of exposure depending on the determined area and the determined value. An associated system is also described.
