Abstract
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.
