Abstract: A rear-view assembly for a vehicle includes a mirror and an anti-dazzle adaptor which is movably mounted in front of the mirror and which includes an optical cell having at least one electrically adjustable luminous characteristic selected from the group consisting of transmissivity and reflectivity. The anti-dazzle adaptor for a rear-view device of a vehicle includes an optical cell having at least one electrically adjustable luminous characteristic selected from the group consisting of transmissivity and reflectivity; and means for movably mounting the anti-dazzle adaptor on the rear-view device of the vehicle.

Abstract: The invention relates to an article comprising a glass sheet and having an etched pattern, and to a process of manufacturing an article comprising a glass sheet and having an etched pattern.The glass sheet 11 is a chemically tempered glass sheet, and the pattern comprises one or more grooves 10 etched into the article using fluorine ions to a depth of less than 2 .mu.m. The etched grooves 10 constituting the pattern may be formed in a layer 12 of inorganic material such as SiO.sub.2. They may have a width of less than 10 .mu.m and the spacing (p) between two adjacent grooves may also be less than 10 .mu.m.
