How about TRI-focals? Any benefit there?

I have both progressives and lined bifocals. The progressives are
easier to get used to (no annoying line) and have a mid-range around the
middle of the lens that is good for things like looking at a computer
screen. The downside to progressives is the "sweet spot" for reading
(e.g. newspaper, sectional chart) covers a smaller area than the reading
part of a lined bifocal. For me this is a bigger problem than for most
because I lack binocular vision (learning how to land a plane took me
longer than most). Even though ophthamologists have told me that
progressives are a bad idea for folks like me with no depth perception,
I still use them because my job requires me to spend so much time
looking at a computer screen.

Can't beat a lined bifocal for reading. But I still don't use them
generally for walking around because the line is bothersome. Dunno how
some can get used to trifocals, but that's the only solution I know of
besides progressives for the "mid-range" (computer screen) issue.
