I am looking for advice on progressive lenses

I had my eyes checked prescription a couple months ago and ordered
glasses from a local optical supply (Hakim Optical).

I have had my glasses done by a smaller independent optician for the
past 3 pair of glasses but decided to try Hakim.

When I tried the glasses I found that my Vision in the add portion of
the lens was next to nonexistent. Reading was very difficult it seemed
that there was only a very small slit at the bottom of the lens that
was usable.

Original Rx
Shp    Cyl    axis    add
OD    -075    -325    100    +175
OS    pl    -375    082    +175

New Rx

Shp    Cyl    axis    add
OD    -075    -325    100    +225
OS    pl    -375    082    +225

When I returned to the store they asked that I return to the
Optometrist to verify the Rx.
I did and they added instructions that the lenses should be the same
base curve and that the lenses selected should give the widest field of
vision possible.

Returned to Hakim and new lenses were ordered.

With the new lenses the left eye was better but right eye now was not
good close and not good distance!

I booked a second Optometrist and had Rx rechecked.

The RX now is different once again although the optometrist said the
new one was not that far different for the one done a couple of months
ago.  The second optometrist used an automated system to check the
prescription and then followed up with the more usual projector charts
and lenses flipped in front of me.

3rd Rx
Shp    Cyl    axis    add
OD    pl    -325    101    +2.00
OS    +0.25    -375    080    +2.00

They did vision check with my new lenses and found then sorely wanting.
The base curve was different from my original glasses and the location
of the progressive transition was not done properly.

I returned to Hakim to with fire and brimstone that they did not make
what was required and asked for refund.  I had to force a call to the
district manager to get some response but I do believe that Hakim is
now trying to get things corrected. They are now offering to make my Rx
using the latest and greatest Nikon lens or give me a refund. They have
also switched from my local store to a more central store with their
"best optician".  The optician at the second store took some time
with me to check for the best Rx and is saying that Rx#2 is the best by
having me read close and distant text with corrective lenses in front
of my original Rx.

My initial reaction was to just take the money and run, however I do
not want to be so stubborn as to refuse a good offer from Hakim
attempting to solve my problem.

Any advise on

1- What is the real difference between Rx #2 and Rx # 3?
2- Is there a preference between the automated vision tester and a
properly done "old style" exam?
3- Any opinion on Rx#2 as selected by Hakim or should I go with Rx#3.
Hakim will do either for me.
4- Is the new Nikon lens that much better than the Essleor lens I had
before?

Thanks in advance for any replies
