A method for controlling an ophthalmic system including at least one optical element, at least one measuring sensor, at least one interface for communication with a communicating external electronic device, and at least one processor connected to the optical element and used to control a variation of a functionality relating to the optical element. The method includes: obtaining at least one measurement using the sensor, selecting at least one piece of information obtained by a communicating external electronic device, determining an instruction based on the measurement acquired by the sensor and the information obtained by the communicating external electronic device, and executing the instruction by the processor to control the variation of the functionality relating to the optical element.

The invention relates to an ophthalmic device including an electrically controllable amplitude variation cell, in particular an electrochromic transmission variation cell. More particularly, the cell () comprises a main convex surface on the front. This arrangement makes it possible for the cell to process a lateral luminous flux (RP), unlike cells in the prior art (AA).

The invention relates to the field of management of an active lens and more particularly to a management system comprising an active lens (), a first sensor () arranged to measure data relating to an incident light on the active lens, a control unit () designed for controlling the active lens according to data measured by the first sensor, wherein the management system further comprises a second sensor () arranged to measure data relating to a light transmitted from the incident light through the active lens, the control unit being further designed to adjust, according to said data measured by the second sensor, the control already performed according to said data measured by the first sensor. Thus the management system allows taking into account data relating to the light passing through the active lens as a feedback in order to finely control the active lens.

Method for producing a plastic film containing a compound absorbing ultraviolet radiation comprising (a) depositing an alcoholic solution of polyvinyl butyral on a transparent plastic support film, (b) evaporating the solvent from the alcoholic solution of polyvinyl butyral so as to form a polyvinyl butyral layer on the transparent support film, (c) printing the polyvinyl butyral layer with an ink absorbing ultraviolet radiation (UV absorber) in a pattern, (d) heating the transparent plastic support film, coated with the printed polyvinyl butyral layer so as to enable at least part of the UV absorber to pass from the polyvinyl butyral layer to the plastic support film, (e) removing the polyvinyl butyral layer, preferably by washing with a suitable solvent. The application also relates to the film obtained by this method and the use of this film for producing a photochromic element with a spatially non-uniform behavior.
