Convex glass

Does anyone know of a source for (or even the correct name for) a
large piece of convex glass that fits over a portrait picture?  This
is the type of glass that fits into an ornate oval frame and usually
covers a photograph rather than a painting.  The photograph is
slightly convex as well.
