    摘要: A method of determining at least one behavioral parameter of a wearer for designing an ophthalmic eyeglass lens includes: a) acquiring a first data set from a first representation of the head of the wearer in three dimensions; b) determining the relative position in space of at least three particular points of the head based on the data set; c) acquiring a second data set from a second representation of the head in a natural posture, including at least one image of each of the three particular points; d) identifying the image of each of the particular points from step b) on the representation of step c); e) deducing information relating to the position and/or to the orientation of the head of the wearer during the determination of the second representation from this identification; and f) determining the behavioural parameter of the wearer based on the information from step e).

    摘要: Disclosed is a method of determining at least one visual behavior parameter of an individual, including: determination of the position of the center of rotation of at least one eye of the individual in a first reference frame tied to the head of the individual; capture, with the aid of an image capture device, of at least one image of at least one part of the body of the individual in a second reference frame, determination of the position and the orientation, in the second reference frame, of the first reference frame tied to the head of the individual, by searching for the position, in the second reference frame of a distinctive zone of the part of the body of the individual; determination of the position of the center of rotation of the eye in the second reference frame; and determination of the sought-after visual behavior parameter.

    摘要: An optical instrument includes: a collimation element (30) having a focal distance; a point light source (25-27) with a wavelength of between 700 and 1000 nm and a diameter less than or equal to a fiftieth of the focal distance, placed at a first focus of the collimation element, so that the light becomes a beam (20) of collimated light; a backscatterer (12); a support for receiving an ophthalmic lens (14), with the collimation element, support and backscatterer being placed so that the beam of collimated light encounters the lens location (15) where micro-etching is present; an image analyzing element (32) and an image capture element (31) linked to the analyzing element and including an objective lens (35) placed at a second focus of the collimation element, which objective lens is developed to provide the analyzing element with images of the backscatterer in order to identify and locate the micro-etching.

    摘要: An instrument has a light-emitting and light-receiving assembly including an image capture unit and image processing unit; a backscatterer and an opening provided therein; a support for receiving an ophthalmic lens between the assembly and backscatterer, the assembly, support and backscatterer placed so that an incident light beam traverses the lens, strikes the backscatterer, returns and re-traverses the lens to arrive at the capture unit; the light-receiving assembly, the support, backscatterer and opening configured so that the assembly receives light from the beam; and the opening and a drive device for cyclically driving and making the backscatterer perform an identical movement in each cycle, configured so that a fixed zone opposite the backscatterer includes at least one part of which, over the course of a cycle, every point is at times perpendicular to the opening and at times perpendicular to a solid portion part of the backscatterer.
