* WOW at Delivery
This time, its Autograph II SV:
1.67 Transitions with AR
RX:
R -7.25 -1.75 x 165
L -7.25 -0.75 x 50
Supplied these Advanced Fitting parameters:
VD = 14mm.
Pantoscopic tilt = 9.5 degress (!)
Panoramic Frame angle (wrap angle) = 4 degrees
Pupil position = 2mm above mechanical center
"Just incredible clarity!"
Rx change: only-0.25D O.U.!!!!!!
Condition of older, AR lenses: Good (some light scratches).
FWIW - Go "Personalized", and you won't go back!

I was Pm'd about how I take the Advanced fitting parameters:
Pantoscopic tilt = Zeiss, "plumb" gauge
Panoromaic (wrap) angle = Rodenstock Impression ILT tool, but any protractor does almost as well.
VD = standard Distometer
I'm not saying these tools are the onlybe-all/end all, but they are what I currently use/trust.

keep sellin' 'em, Barry. Shamir loves you.
Hey, It doesn't have to be Shamir. Pick *your* favorite lens/brand, but make it free-form/personalized!Originally Posted by Jacqui
Take that, internet dispensing!

I discovered today that the so-called "advanced-fitting:" parameters I listed *were not* used in any POW compensation for these Autograph II SV lenses.
Makes the atoric/overall lens optimization for these free-form lenses, in my mind, even *more* impressive.
I really think that this new class of surface -optimized, free-form generated lenses deliver at least an order of magnitude more optical correction/refinement than present, "corrected curve" lenses have. I dare say that they represent a significantly greater leap of opticval correction than the original, individually-calculated Abbe-Zeiss "Punktal" series did, compared withg what existed before it.
What say you, Darryl Meister, in this regard?
Barry
Actually Barry, I fit one of my daughters in an atoric and she loves it. These were made with a "generic" program in the -3.00 ish range.
Barry, is that because they neglected to use the information you provided, the parameters were so close to the defaut values that they could be ignored, or is this lens not optimized for position of wear?
Do you have any experience with the Nulux EP? The availabilty of a higher Abbe lens in an even higher index of refraction makes this an excellent lens for these powers.
I tried to order an Auto 2 with a custom inset- they can't do it yet- maybe with a future version they said. Makes me wonder what optical optimizations Shamir is using besides atoricity and multiple corridor lengths. Looks like I'll have to use the Individual, ID, or Lifestyle ID. I'd rather do this in Trivex for safety reasons (monocular vision), so I'll probably use the Lifestyle. I sure would like to avoid what I did last time for this client- turn the lens to eliminate the inset and then create a new 180 line.

Experience is the hardest teacher. She gives the test before the lesson.
Robter,
Auto II SV's algorithym is NOT a POW compensated lens (at this time). Therefore, they do NOT use advanced fitting values (especially the ones I supplied. Though I'm sure the design uses some typical defaults for the general optimization.
As far as Progressives go, I think the current top of the line is either Hoya ID or HOYA ID MYstyle.
FWIW

Barry;
ICE-TECH has been using this compensation for a number of years. I think we were the first to attempt this in freeform lens production.
Taking all those measurements is impressive to the customer though . You will be remembered.
Yes, I agree. I learned a term for this from Anthony Fulco, sales manager for 21st Century Optics (NY). He called it "contact points". He emphasized that these *contact points* are very important and essential to the professional impression you'll leave with a client.
How many of us (mea culpa!) get lazy with adults, and neglect to "re-take" their Pds with a pupilometer, especially when we (or they) are pressed for time?
How many of us have had clients say "Aren't you going to *re-measure* me?" when we don't?
And, now that I have been more diligent witrh respect to re-taking their IPD measurement for every new transaction (well, not always...), I've noticed that their values *do* change over time, even if they are an older/middle-aged adult.
Do yourself a favor: Don't neglect these "contact points". Especially with respect to other discussions on this board, it is but one important skill, benefit & value that cleary separates us B&M dispensaries from the *internet*
FWIW
