RE: the glasses...it's not something I've been able to figure out how to
mention, but the Narn pride themselves on their physical perfection. Hence
there is no market for physical aides; it's something to be ashamed of. So
they have to crib stuff from other species, like glasses that have a
prescription close enough to be useful.
I have *no* idea how to work that into a script, and am not sure it is
even a good idea to do so.
Kosh was otherwise engaged....
