Well, I think he doubled checked whatever it was they
came in to be sure they had the add on the label. This
might explain why the consultant couldn't give a center
optical size though. That's a bit reassuring.

He seemed to be expecting just a bit of translation due to
my lower lids when looking down. You wouldn't expect
any at all?

Not mine any more. We just tried them and I left with
the Cooper vision softies I've been wearing for a few
weeks now. Distance center in dominant eye and near
center in other. A modified monovision I guess.
It works but I don't like the compromises. Blurry when
looking left etc. If all else fails they're acceptable and
better than reader spectacles. He didn't have the
55s in stock last time I lost one and he gave me the
proclear version. I think they're clearer but don't compare
with the Tangent Streak RGP's clarity. The vision through
the RGPs really meets my expectations (which is basically
no compromise) which is very encouraging after all the
compromise admonishions from the first doc when I
couldn't really see.

I'm hoping my smaller pupils 3.5 mm will minimize this
and with a bit of head positioning adaptation should be
a non issue.

So is there anywhere that makes "money no object" totally
custom segmented lenses? What if I like the trifocals but
want the intermediate segment wider, making the bottom
segment smaller? No, I'm not a "money is no object" guy
but I could go 3 or 4 times what most are willing to pay.
