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.

Yeah, that's what I have, George. And that's what I'll probably continue to
use for long stints at the computer. I was hoping my new glasses would cover
everything, but I think I'm asking too much. One happy surprise is that it
really improves my sight picture with handguns, because the distance-viewing
lens now extends my depth of field in the close direction enough to see the
front sights sharply. I haven't been able to see the front sight *and* the
target well for close to 30 years.

Maybe I'll even try an iron-sight rifle again.

But reading and driving are great. And they haven't caused me any trouble
with distance perception. At least, I haven't fallen down so far. g
