That is true; quality control that fails can fail pretty much
anywhere.

I wonder whether the double-vision thing is just from having lenses
that aren't aligned with each other (basically, a bent bridge) or
rather some optical problem with the lenses themselves.  Consider
aligning them yourself-- gently-- before you give up on them.

When I get glasses with flat base curves, I tweak them until they give
me identical reflections of distant objects when I look at them.  With
curved lenses, I tweak them until the reflections in the lenses behave
as though they come from the same continuous surface-- that is, as if
the two lenses were parts of the same single lens in the way that a
reflection rolls across them.  This method allows me to align the
lenses to within a small fraction of a degree.  (The technique might
not work for plus prescriptions.)

I have to touch up the alignment periodically due to wear and tear,
the same way I have to reset my nose pads once in a while, or bend the
temples back in because they have spread out a bit.
