    摘要: The invention relates to a device (1) for preparing an ophthalmic lens for machining, that comprises a holder (100) capable of maintaining said ophthalmic lens, blocking means (400) including at least one blocking accessory (450) and a handling arm (401) for said clocking accessory, an acquisition device (200) capable of acquiring an image of the ophthalmic lens, and electronic and/or computer processing means (700) capable, on the one hand, of deriving an optical reference of the ophthalmic lens and, on the other hand, of driving the handling arm and/or the holder in order to apply said blocking accessory against the ophthalmic lens in a given blocking position. According to the invention, the blocking means and/or the holder include at least one marking element and the electronic and/or computer processing means are adapted for identifying the position of said marking element on an image acquired by the acquisition means and in which an image of said marking element appears.

    摘要: The invention relates to a method of determining at least one behavioural parameter of a wearer with a view to the design of an ophthalmic lens for a spectacle frame of this wearer, comprising the following steps: a) the acquisition is carried out of a first data set corresponding to a first representation of the head of the wearer in three dimensions, b) the relative position in space of at least three particular points of the head of the wearer is determined on the basis of this data set, c) the acquisition is carried out of a second data set corresponding to a second representation of the head of the wearer in a natural posture, comprising at least one image of each of the three particular points of the head of the wearer, d) the image of each of said particular points of the head of the wearer whose relative positions in space were determined in step b) is identified on said second representation of step c), e) information relating to the position and/or to the orientation of the head of the wearer during the determination of said second representation is deduced from this identification, f) said behavioural parameter of the wearer is determined on the basis of the information deduced in step e).

    摘要: The invention relates to a device for determining at least one sight parameter of a subject, comprising stimulation means for stimulating the sight of the subject in a predetermined viewing direction, and means for ophthalmological measurement of at least one sight parameter of a subject, said means for ophthalmological measurement having at most one optical measurement axis for each eye. According to the invention, the device comprises at least one optical conjugation system, which is arranged between said ophthalmological measurement apparatus and the right eye and/or left eye of a subject to be measured, and a system for alignment of said optical conjugation system, in such a way as to optically conjugate a point Y and a point E, the point Y being intended to coincide with the optical centre of rotation of the eye concerned, the point E being a point situated on said optical measurement axis, and in such a way as to align the image of said optical measurement axis with the ocular axis of the right or left eye of the subject in a plurality of viewing directions.

    摘要: The invention relates to a binocular multiplexing device for a single-channel ophthalmological instrument for objective measurement of at least one vision parameter of a subject, said ophthalmological instrument comprising means for generating a single light beam, means for collecting a measurement beam by reflecting and/or refracting said light beam against the subject's eye and a sensor associated with said single measurement channel. According to the invention, the binocular multiplexing device comprises first means of optical separation capable of receiving an image beam originating from a stimulus target and of separating said image beam into a right and left ocular stimulation beam so as to stimulate the subject's binocular vision; means of optical switching capable of switching said single light beam selectively onto a right or left monocular light beam's optical path in order to form, after reflection and/or refraction by the eye in question, a right, respectively left, ocular measurement beam, and optical combination means capable of superimposing the right, respectively left, ocular stimulation beam, and the right, respectively left, monocular light beam.
