    I'm not exaggerating.
    +0.50 over the distance (add cut by the same) is sweet in a small room, primarily for the more advanced presbyopes. The cut add also reduces unwanted astigmatism, and of course Zeiss designs a nice PAL with a wide distance zone.

    They might even double as computer/task eyeglasses for some folks (screen carefully) and select nursing home residents.

    It used to be called Gradal RD (room distance) decades ago.

    Well, that's exactly right.

    I overrefracted through these to ascertian the effective add through the upper portion of the lens and it was just about -0.50. So it's what you said.

    And we designed those before with any old PAL, like anyone.

    And truth! If you want a "room design" you add +0.50, and if you want a "computer design" you add +1.00, more or less. And yes, turning a +2.50 progression into a +1.50 progression widens out the near zone.

    And yes, these are digitally surfaced and well-designed.

    But I gotta say that the area of the intermediate and near zones is super-ample. They're just nice.

    I remember my same reaction when I got a pair of Shamir Workspace lenses a few years ago and Robert correctly pointing out my minimal rx probably needing more plus in the distance as it is commonly under-corrected in the chair.

    I have better success prescribing to minimal rx's with this type of lens but recall drk is quite nearsighted- so not sure if I want to change my go to recommendation of single vision for strong myopes.

    That's all I really need to take away from this. And somehow, I need to incorporate this into my everyday vernacular with patients.

    "Sir, you're right, that's not a bad option, but THIS lens is like wearing butter."

    Which US Zeiss locations have you had any luck with? Do all of the 1.74 Individual still get produced in Germany or are there US locations for this now? Its been a few years, but the turn time used to be atrocious.

    I use Walman Optical in Oak Creek Wi.

    They're still being produced in Germany, with both sides being worked for the thinnest possible optics, especially on plus powers. I ordered a pair about 4 weeks ago that looked like this:

    Rt +4.50 -1.00 x 96 add +2.50
    Lt +2.50 -0.75 x 86 add +2.50

    It took 16 days, with I assume a fast track through customs. US produced product has had a seven to ten day turn around, again through Walman.

    Hope this helps,

    OK, a basic question that is shameful to ask.

    I know the answer, but I want reassurance.

    When ordering a FFSV lens (like the Zeiss Individual SV), you provide whatever POW numbers you like, and monocular p.d.s, and..."fitting heights" NOT the pupil height minus 3-4 mm for pantoscopic tilt.

    RIGHT?

    Because it's funny that I have for sooooo many years forgotten that I'm really doing compensations for POW everytime I order a traditional SV lens, by customizing OC height for the frame. (But heck, I always used the same number, 3mm.)

    So now, Zeiss will take my pupil center fitting height, and my pantoscopic tilt measurement and work their own magic. (It might just be 3.1mm or even 2.9mm!)

    Correct. You should not be adjusting the fitting height for FFSV lenses. Most are fit on center. I think the Zeiss Ind SV is a 4 drop from the fitting cross to the prp.

    Not really. Sounds like you are saying they will be adjusting the height, just by a different amount than you would? Which they wont. The fitting height will be whatever you supply. They will be adjusting the lens power and design to optimize viewing for your supplied measurements.
