One can argue that if they do not need to focus it, unless if
they wear glasses and they take them off.

There is such a thing as "universal focusing" setting in viewers.
That's why fixed focus viewers work. 

Whenever I pass the viewer around, I have it focused at this
"universal setting" and don't encourage inexperienced users
to refocus (or change the interocular) unless if I see them
taking their glasses off (I suggest they keep them on, to start)
or I sense problems with unusually wide/narrow spacing of eyes.
