ABSTRACT:
A glass article useful, for example, as a cathode ray tube screen, has a viewing light path which passes through at least one surface region over which the glass is matted by surface pits whereby unwanted specular reflection from that matted region is reduced. The light path also passes through a surface layer formed over a region of the glass so as to reduce the total light reflection from that region of the glass.
