A low reflectance glass surface with improved cleanability is disclosed which
includes
a particular combination of surface structures which produce a low reflectance
yet high clarity glass. The surface structure includes a plurality of islands distributed
at a density of about 60 to about 10,000 islands per square millimeter. The glass
surface also includes a skeletalized silica structure of about 100 to about 400
angstroms in diameter uniformly distributed over the surface. By combining the
various surface structures on one piece of glass, unique properties of low reflectance
yet high clarity are provided, which is particularly suitable for use in picture
frames where any distortion would distract from viewing a picture contained therein
and also in computer or t.v. screens where distortion or glare could produce operator
fatigue or stress. The glass structure is achieved by a process which is readily
adaptable to existing production lines without requiring major modifications. Consequently,
the low glare high clarity glass can be produced economically, allowing use in
applications not previously adaptable to the highly expensive anti-reflection glass
previously available.
