    摘要: The invention relates to an optical device (FILT) for filtering light received, by polarisation or mechanically, from a medium presenting a graphic and/or textual content, characterized in that cycles of opening and closing a vision space, in a visible light spectrum, are realized periodically using the optical device (FILT) at a preset frequency Fd and in that the successive open periods each have a duration (T1) comprised in an interval of values ranging from 15 to 35% of the duration (T) of the realized cycles.
