I insist on progressive lenses with a wide viewing angle. I tried
bifocals once and they drive me crazy.
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'
