Wrap this, please!

Hey, if you were to do a wrap progressive, but not an individualized, how would you do it?

Would you go with the lens with the "best 180" and do an Opticampus comp, or would you do a lens with the "widest near zone" and do an Opticampus comp?

[Robert_S]

I would just go with a design suited to base-curve variance, like the Image. Usually in high-wrap styles distance is paramount, followed by mid range, since they will be used for driving or sports.

Thank you.

I wasn't sure if that was really the answer you were looking for though, but I find the Image works well in all base curves, unlike most designs. The problem you get though is that usually high wraps come in big lens sizes, and you need to use freeform for variable de-centration. Conventional PALs like the Image often won't fit.

There are some PALs coming out now designed for wrap. I know Wiley X uses the Unity Wrap, and we've done probably 20 of them in the past year and a half, no issues. I don't know what Rudy Project is using, but if you can find out from Pech, use that. We've had very happy dispenses with those as well.

Add 0.25 BI OU and you are good to go on most rx's.

I'd restrict the Rx range to +3 D to -2 D for a +8 BC. That should keep the on-axis error to less than .25 DC.

A good idea wrap or not.

and do an Opticampus comp

That might cause more harm than good on a PAL. I'd stick to the the above Rx range, and bump the lens design quality to Zeiss or Shamir for higher powers and/or tilt values.

Thank you, all. Good advice.

There is also the Image Wrap that is available in poly grey Nupolar 8.50BC.
