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'
