Rodenstock Progressive PureLife power check

[Fabian Corio]

Hi everybody,
Does anyone know where exactly I should control the distance power of a Progressiv PureLife?
I understand this lens was designed around fitting conditions, the lab would send me the lens with the measured power (the power I would read off a lensmeter) and the ordered power.

This the Rx. I ordered:
OD +1.50 sph. +0.25 cyl. 70* Add. 1.75
OS +1.50 sph. +0.25 cyl. 125* Add. 1.75

This is the expected power:
OD +1.47 sph. +0.22 cyl. 72* Add. 1.81
OS +1.47 sph. +0.22 cyl. 123* Add 1.81

And this is what I get:
OD +1.48 sph. +0.18 cyl. 84* Add. 1.80
OS +1.49 sph. +0.16 cyl. 113* Add. 1.84

I always assumed that the distance power had to be read exactly where the fitting cross is and that´s what I did in this case, just like I do with Impressions and Multigressivs. If I´ve been right until now, then what I have here is a problem with both axes.
However, my lab insists that I should check it like a ClassicLife. According to them, distance power measurements should be made above the fitting cross (nearby the upper top of the yellow circle). There, the axis values get closer to the ones I should expect.
I would really appreciate your input.:)

While I cannot find any actual information on where to check it, I did find this (except the link didn't work) :(

Ok, here is the search I used: http://www.google.com/search?q=rodenstock+Purelife+fitting+chart&rls=com.microsoft :en-us:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7

In PDF at the bottom of the first search page, pages 101 and 153 both indicate that the lenses should be checked the way you are checking them. Also in the PDF are the numbers for people at Rodenstock that you can call to verify.

Based on the pictures of the lenses that I could find, I would say that you should check it in the center of the circle.

As for the axes being off, in the US those would technically be within standards. Personally I would never send them out of our lab. On a lens that precisely made, there is no reason that they should not be more accurate. (My personal rule is 2 degrees or less on <1.00 cyl power, 1 degree or less on >1.00 to < 2.00 cyl power, and 0 degrees off on >2.00 cyl power).

Hello WFruit, thank you very much!
Your PDF http://cfile29.uf.tistory.com/attach...4D5E097E0A3E47 made me aware that the lenses I´ve received are non free form conventional plastic PureLife pals (like the drawing in page 136).
However and to add more confusion, these come with the same ink markings as those in page 96 (PureLife Free) and both measured and ordered powers are printed on their envelopes.
The question arises whether I check them like Multigressivs/Impressions or PureLifes.
The difference between PureLife Free and PureLife markings is 4 millimeters, should I "split" it and check the power in the upper top of the yellow circle, as my lab suggested? It seems to be an unscientific approach and I do not like it.:finger:
By the way, Rodenstock has his own standards (RN6180-1) and off axis tolerance up to 0.50 cyl is +/- 7 degrees.
I´ll try to contact their Lens Product Manager.
Thank you again!
Best regards,
Fabian.
