I tried progressive lenses three times, and each one ended in
frustration, because the "reading" area is limited to a circular "bulls
eye" that makes head swiveling mandatory for covering a wide area. If
anyone knows of a progressive without this characteristic, I'd be first
in line.

Please tell me who makes a progressive lens with the same viewing
angle as an executive (Franklin) bifocal? I have been looking for
a progressive lens that will allow me to read large blueprints or
schematics and see three monitors wide without swiveling my head
for nearly 20 years.

With good progressive lenses, distance to the monitor is no problem nor
is reading or working as close as 6 inches. I can lay a newspaper flat
on the table in front of me and read it from top to bottom without
excessive head movement - try that with bifocals!
For me, the wide angle is important - the regular progressives produce
'tunnel vision'

I must also concur with Dale, et al. I also have a set of glasses I had
the Optometrist prescribe, and I can not use my bifocals anymore, too
much head movement... That was th best money I have spent in a long
time. One thing you might consider is adding an AR coating to them.
I use ONLY glass lenses, (no polycarbonate), and have them AR coated.
The coating is finally coming off my bifocals after 5 years of heavy
cleaning. The AR coating is wonderful if you have specular lighting
events around your OP area. With an AR coating, if you clean your
glasses right, (ultrasonic cleaner), you will not even see them...
