    摘要： The invention concerns a method comprising the steps of:
    a) illuminating a pupil (30) of the (3) eye of a subject by means of a light source (12);
    b) acquiring at least one picture of said pupil comprising an image of the reflection of said light source on the retina of said eye, by means of an image-capture apparatus (10);
    c) determining a refraction feature of said eye from at least a geometrical feature, a positional feature, or an intensity distribution of said image of the reflection of said light source
    wherein optical distances (d source , d cam ) between said pupil and, respectively, said light source and said image-capture apparatus, are different.
    An associated device (8) is also described.

    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.
