Abstract: 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 (3) 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 (1AA).

Abstract: The invention relates to an ophthalmic device (1) which includes an electrochromic cell (3) comprising at least two transparent layers (4, 5) having curved inner surfaces (4a, 5a) and defining therebetween a closed recess (6) filled with an electrochromic composition (7), the recess (6) being defined peripherally by a sealing gasket (11) made from an adhesive material (20), the sealing gasket (11) being suitable for keeping the two transparent layers (4, 5) assembled together.

Abstract: 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.
