Disclosed is a binocular optoelectronic device wearable by a user for measuring a light sensitivity threshold of the user, including: a diffuser configured to face eyes of the user; at least one light source for emitting light toward the diffuser. The diffuser includes predetermined parameters allowing to provide a quasi-homogeneous light diffusion to at least one eye of the user from light emitted by the at least one light source.

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.

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.

The invention relates to an ink-jet printing deposition method including a compensation of deviations (&#x3b4;l, &#x3b4;l, &#x3b4;l, . . . ) of ejection nozzles (. . . ) carried by a printing head (). To this end, the deviations are measured first at the moment of the deposition, and then, during the deposition, each nozzle is activated when it shows a shift in relation to the point on a support where the substance is to be deposited, substantially opposite the deviation of said nozzle. Said depositions carried out in this way do not comprise accidental Moir&#xe9; patterns.
