OK, I tried (just for the experiment) moving my chair down, so I'm viewing
through the upper lenses. That's not bad, but they're focused just a bit too
far. I know that the bottom lenses focus too closely.

Real cheap screw solution. Go to Walmart or Dollar General and
get a set of reading classes with the correct focal length for
your computer glasses. Should run 5 to 10$ US. You may find you
want/need several pairs in slightly different focal lengths as
the day progresses and your eyes get tired. Yellow tinted can
also help.
