Abstract: A system for determining a value of a magnitude associated with a subjective value of an optical feature of at least a corrective lens adapted to an eye of a subject, by implementing a subjective test where the subject is asked to describe his visual performance in a plurality of real optical conditions by choosing one descriptive answer among a set of possible descriptive answers. The system includes one or more processor programmed to collect the results of the subjective test, performed by asking the subject to describe his visual performance in each real optical condition of the plurality of real optical conditions by choosing, for each real optical condition, one descriptive answer, the results comprising each descriptive answer chosen and the corresponding real optical condition, and determine the value of the magnitude by taking into account the initial model and each descriptive answer collected.

Abstract: Method for determining an ophthalmic equipment, the method comprising: —collecting (S100), for a plurality of reference wearers having worn at least an ophthalmic equipment of the set of predetermined ophthalmic equipments, a first plurality of wearer parameters values, —creating a plurality of reference datasets (S200), each reference dataset comprising a subset of the first plurality of wearer parameters values, each subset of the first plurality of wearer parameters being different for each reference dataset, —for each of the reference datasets, determining, a model intended to be used to determine at least an ophthalmic equipment (S300), —collecting, for a given wearer, a second plurality of wearer parameters (S400), —selecting, as a function of the second plurality of wearer parameters, a model among the models associated to the plurality of reference datasets (S500), —based on the selected model, determining at least an ophthalmic equipment (S600).

Abstract: A system for determining a personalized value of an optical feature of a corrective ophthalmic lens which is intended to be worn in front of an eye of an individual for correcting his vision, the system including: a trial optical corrective device adapted to be place in front of an eye of an individual, the trial optical corrective device providing a correction to an individual complying with an initial value of an optical feature; an eyewear adapted to be placed in front of the trial optical corrective device worn by the individual and adapted to immerse the individual in a virtual environment, the eyewear being designed to present, in the virtual environment, a visual task to the individual adapted to determine an adjustment value; a processing unit programmed calculate a personalized value of the optical feature based at least on the initial value and the adjustment value.

Abstract: A method for determining a postural and visual behavior of a person, the method comprising:—a person image receiving step during which a plurality of images of the person are received,—a context determining step during which the plurality of images of the person are analyzed so as to determine context data representative of the context in which the person is on each image of the plurality of images,—an analyzing step during which the plurality of images of the person are analyzed so as to determine at least one oculomotor parameter of the person,—a postural and visual behavior determining step during which a postural and visual behavior of the person is determined based at least on the at least one oculomotor parameter and the context data.
