Have a gentleman with a +12.00 distance and an 8.50 add. Wearing an aspheric lenticular round seg style. Wants to know what other options are available. My lab guru is away for the day so I thought I'd throw this out here. He'd really prefer a flat seg.

Options for an 8.50 Add

Younger has a FT28 and FT35 "Special Adds"; maybe not special enough for you tho as they only come to +8.00.

We just had a Free-form round seg-bifocal with a backside add in +13.50sph +3.50 cyl with a +3.50 add. The front was spherical, but if you stacked the adds you could do the same with one on front, one on back. You could get to +8.00 in theory by using a bifocal blank vs spherical.
It was an ICE-TECH dual zone and came out very thin in 1.74. It looked amazing, like it was only a +7 or so.

Here's the +11.50 with the 8.50 Add. 350 on the front seg and 5 on the back in a 1.67 blended. 4.9 at thickest point on the back bubble.
I'm getting dizzy counting all of the optical centers (four)!
Did you start with a 1.67 ST lenticular? I didn't know that was an option. The back was surfaced on a free-form generator, creating the power curve and the round seg? What are the front and back curves, and are they aspheric or optimized in any way? Most importantly, how is your client getting along with them?Science is a way of trying not to fool yourself. - Richard P. Feynman
