I have been flying with progressives for some ten years. I never had
a problem adapting to the progressives, and am at a loss to
understand why anyone would want to deal with lines in their vision
if they didn't have to.

The reason may be due to a person's prescription. I can't stand
progressives because, for my prescription at least, there is almost no
peripheral vision. To see anything a few degrees off-center, I had to turn
my head. When reading a book (or worse, a chart), only a few words in a
paragraph were in focus. With my "hard line" bifocals, I have normal
peripheral vision for both distance and reading, and the hard line is not
in my "distance" field of view. Of course, I had them custom made by
someone familiar with the tasks associated with flying.

Different strokes...

When I was 30ish I got a physical and eye test for my
PPL, and found out I was near-sighted, needed glasses
to fly. I was (still am) a nerdy book-worm type, but I used
eye exercize and now at age 55 don't need glasses to
pass the eye test. I'm also a smoker (since age 12) and
a drinker (since age 30) , which is claimed to be causal
to coronary hardening.

What I did was used a pirates eye-patch to exercise each
eye. I made sure I could focus on distant land scape and
also read the fine print on bottles, with either eye.
However, I still prefer some correction, for exceptional
clarity, but the required correction is reduced, IOW's
my eye's have improved using excercize.

IIRC, there are 6 muscles in the standard eyeball that
distort the lense to produce focus, so by boosting
those muscle stengths one can improve vision.
