Thank you for not calling me an idiot like Dr. Grant did.

Everyone seems to be calling the Rx of the OP low power, but with a +2.25
add on top of a +1.25 sphere, I would call it at least moderate.

My experience is that hyperopes (farsighted with a plus Rx for distance) are
more sensitive to chromatic aberration. And since hyperopes are small
percentage of the population, their special problems are often mistreated by
lens dispensers. Since the OP specifically claimed that he is "very
sensitive" to chromatic aberration (perhaps because he is a hyperope?) ,
then it might be of more concern than normal.

True, but you'll probably not notice that small difference.  My reason
for (rarely, as in this "choice") choosing the polycarb is the greater
production/availability of polycarb progressives over 1.67 means that
you might get better optics otherwise.  By that I mean the manufacturers
may have put more effort into the designs of the polycarbs, since it is
by far more commonly used, esp. in the lower powers as in this case.
But that's just a hunch based on experience.

w.stacy, o.d.

However, the abbe value for 1.67 is slightly higher than polycarb, which
means 1.67 should have less chromatic aberration.

Locked out of free choice by someone?  Anyway if I had to choose between
the lesser of 2 evil lenses, I'd go with the poly in your Rx, because
it's pretty low power so chromatic abb will not be a large factor...

w.stacy, o.d.

Yea, I think that would have been my first choice... If it was an option.
It's not. The choice is between polycarb or 1.67

 Not sure if I missed it, but someone should recommend a Trivex ECP by hoya.  It's a great, thin, strong, light lens with little aberration.  I wear them myself and love them.

Physio 360m is a much better lens. Pay the $20.00 and be
happy it was well invested.

Airwear is fine for lower scripts. Chromatic aberration is
inconsequential at these scripts. The benefit of 1.67 is
it is virtually unbreakable - more so than airwear.
Airwear is cheaper and great for rimless fits.

Quick, stick with the physio 360, multicoated and choose
the material you are happy with.\
   
I've decided on the Physio 360 (over the Physio).
I have decided on the Air Titanium drill mount frames.
I don't know what "Airware" is.... Is that another term for
polycarb?

I'm not sure what lens material will make me happiest :)
The viable alternatives are polycarb and 1.67

I have no qualms about the extra money if there
is any advantage at all to the 1.67 over polycarb
given my Rx.

For all I know polycarb might be better than
the 1.67 given my Rx.

I have no idea if the materials effect the transitions
performance differently.

At the moment it sounds like I'm going with the 1.67

thanks,

You are correct that 1.60 is not available for Varilux Physio 360. Therefore
I would strongly consider the Varilux Panamic which is available in 1.60.

I don't think that's an option. I think the Physio 360 is only
offered in polycarb, 1.67, and they just added CR-30 which
has been recommended against due to the drill mounts.

thanks,

Polycarb has the worst chromatic aberration of any commercially available
lens material (measured by abbe value) regardless of index. Avoid it like
the plague.

Except for polycarb, the higher the index, the worse the chromatic
aberration. 1.67 is overkill for you. I would go with 1.60 at the most.

Ok, Doc is really advising against CR-30 and recommends
polycarb, or as an alternative 1.67, 'cause I'm getting drill
mounts. Air Titanium rimless.

O.D. +1.25 sph add +2.25
O.S. +0.75 -0.25 add +2.25

Transitions (grey)

Yea, I know, I don't need the 360... it's only $20 more.
I don't play Jai Lai

So...
I don't expect the difference in thinness to be measurable.
I don't expect the difference in weight to be noticeable.

Is there any possibility I could see any material caused
abberations with either (I'm very sensitive to that sort of
thing)?
Would there be any difference with the transitions
performance?

Price difference is about 10% of total so not a factor
if there is any advantage to the 1.67
