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.
