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.

> Buddy, you are an idiot. > [quoted text clipped - 8 lines] > 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, -Quick

Buddy, you are an idiot.
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.\

Therefore I would strongly consider the Varilux Panamic which is available in 1.60.

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.

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.

Physio 360 Crizal Alize with Clear Guard (gold) 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
