A method of controlling a programmable lens device comprising a programmable lens and an optical function controller, the programmable lens having an optical function and extending between at least one eye of the wearer and the real world scene when the device is used by the wearer, and the optical function controller being arranged to control the optical function of the programmable lens, the method comprising: an optical function data receiving step during which optical function data relating to the optical function of the programmable lens is received by the optical function controller, an optical function modifying step during which the optical function of the programmable electronic lens device is modified by the optical function controller based on the optical function data.

A selective dyeing method is used for dyeing a substrate, selectively within a first exposed surface portion of said substrate. For this purpose, the substrate consists of a material that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion of the substrate in a second portion of the exposed surface. The substrate is heated such that the dye penetrates a pervious material which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.

Selective tinting method

The invention relates to a transparent optical component having a cellular structure, comprising a network of walls (), that forms a set of cells () that are juxtaposed parallel to a component surface. In order to produce such a component, an irregular set of points () in the surface of the component is determined, each point being used to form a center of one of the cells. A position and an orientation of each wall are then determined such that the set of cells forms a Vorono&#xef; partition of the surface of the component. The component has a level of transparency that is compatible with an optical or ophthalmological use.

Production of a transparent optical component having a cellular structure

The invention relates to a selective dyeing method used for dyeing a substrate (), selectively within a first exposed surface portion (S) of said substrate. For this purpose, the substrate consists of a material () that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion () of the substrate in a second portion (S) of the exposed surface. The substrate is heated such that the dye (C) penetrates a pervious material () which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.

A transparent optical component comprises a set of cells () juxtaposed on a surface of the component. Each cell encloses a determined substance so as to endow the component with particular optical characteristics, and two neighbouring cells are separated by a wall (). Some walls are not straight at the surface of the component, so that the light diffracted by the walls does not form any luminous glint or any flashing. In particular, the walls can be curved or made up of straight segments disposed end-to-end.
