    Abstract: The invention relates to a method for determining a progressive ophthalmic device for personalised visual compensation for an individual, according to which the following steps are performed: a) in a first data acquisition phase, determining at least at a first time preceding the appearance of the presbyopia of this individual, at least one value of at least one individual parameter of said individual, and recording each value of the individual parameter of the wearer in a database, in correlation with an associated temporal indicator, b) in a second determination step of the progressive ophthalmic device for personalised visual compensation, determining a desired value of at least one geometric or optical parameter of said progressive ophthalmic device for visual compensation, taking account of said at least one value of the individual parameter determined in step a) and the associated temporal indicator.

    Abstract: The invention relates to an optical device (10) adapted to be worn by a wearer comprising at least: —a programmable lens (20) having an adjustable optical function and extending between at least one eye of the wearer and the real world scene when the optical device is worn by the wearer, —an optical function controller (30) comprising —a memory (32) storing at least computer executable instructions; and —a processor (34) for executing the stored computer executable instructions so as to control the optical function of the programmable lens (20), wherein the computer executable instructions comprise instructions for adjusting the optical function of the programmable lens (20) over a period of time determined so that the wearer does not perceive the adjustment of the optical function.

    Abstract: A device for determining a head freedom area of an optical lens adapted for a wearer looking at a specific point in a scene through the optical lens comprises at least one input adapted to obtain optical lens data representing the optical features of an optical lens, to obtain wearing data and fitting data representative of the wearing conditions and fitting parameters of the optical lens, and to obtain a specific threshold value for an optical performance criterion; and at least one processor configured for determining the head freedom area that corresponds to the head positions of the wearer that provide optical performances greater than or equal to the specific threshold value when the wearer is wearing the optical lens in given wearing conditions upon given fitting parameters and looking at the specific point in the scene through the optical lens.
