Progressive Lens Choices



I'd like to solicit advice about choosing progressive lenses for two
pairs of eyeglasses, devoted respectively to generalized and
occupational uses.

I am 51 years old, with no history of eye diseases or surgeries. My
primary generalized needs include driving and shopping. My primary
occupational use is at a computer, with a large monitor about 30" from
my eyes. I also play the piano, with the music stand and keyboard
each about 20" from my eyes. I would add that the frames I'm
considering (Silhouette 7481) offer generous areas above and below the
pupils (Eye=47, Bridge=20, Vert=35). My current prescription is (Eye,
Sph, Cyl, Axis, Add):

OD -3.75 +2.75 x175 +2.00
OS -4.00 +1.50 x155 +2.00

I used Varilux Comfort lenses 3-5 years ago, with a similar distance
prescription but a reading correction of only +1.00; I found the
peripheral image blur fairly annoying. Lately I've been using single-
vision lenses, sliding the frames down my nose for monitor viewing and
looking over them for reading. I can see very well in these ways, but
I've grown weary of the antics!

Some specific issues that concern me:

1. Would I benefit substantially from the newer, individually designed
progressive lenses that use free-form technology? On what basis might
I choose between, say, the Hoya iD, Shamir Autograph, Zeiss
Individual, or other models? Are there desirable alternatives at
lower technology levels and prices?

2. Would I fare better in occupational use with an "office" type lens
or with a regular progressive lens suitably adjusted (e.g., by moving
some of the "Add" power into the "Distance" prescription)?

Many thanks for your time and effort in reading this.
