If you have links to information about Asia Fit Oakleys, please leave a link/comment.

Introduction
If you're Asian, then you may find that Asia Fit versions of the Oakley models will be more comfortable for you because of your high cheekbones, flattish nose and the shorter distance between the nose and ears (as compared to the typical Caucasian). Asia Fit versions are less likely to "sit on your cheeks" (unless you're like @Skyler and doesn't mind it so much!!)!!

I'm going to make a start on this and try to gather any useful information and links that may help people looking into Asia Fit Oakleys.

Nomenclature
According to Oakley, the term is "Asia Fit" and NOT "Asian Fit", although IMHO, I think that they got it wrong because you wouldn't say "America Fit". You'd say "American Fit".

General Information
Some of the older Asia Fit styles actually have a different frame geometry, so beware if swapping lenses without checking! (@Markman69)
If the frame angles are slightly different, it requires different lenses due to the XYZ positioning (arab_pete, O-review.com)
Ruben Suarez (rsuarez1982, O-review.com) suggests that the lighter lens colours of Asia Fit appears because in Asia, it's disrespectful to not be able to see one's eyes.
Usually, difference is just different sized nose-bombs (@flyer). Different sized sport nosebombs were released after 2005 (Dann, O-review).

Asia Fit Oakleys Which Have Exclusive Differences (besides Nosepieces)
A-Frame has different frame geometry at bridge (EastCoast, O-review.com)
Badman has a different geometry and Lenses are not interchangeable (@Skyler)
Fives Squared Asia Fit lenses will fit in normal frames (albeit slightly looser) (@nofair), but not vice versa (@SMman, @NoFair, @Zax). They have a different frame geometry (@Zax)
Fives Squared 3.0 frame is different (@Zax)
Flak 1.0 frame is flatter (@the piper)
Flak 2.0 frame is different (@Zax)
Flak Draft frame is different (@Zax). The Asia Fit lenses are longer where it fits into the frame. Meaning Asia fit lenses won't fit into a regular Flak Draft, and regular lenses are loose in a Flak Draft Asia Fit. (@DKO)
Flak Jackets have different colourways (dann, O-review)
Frogskins Difference is slightly deeper nose bridge and different colour combos (@SoulFulFrog). Ear stems also shorter (@Trucker360)
Garage Rock has different frame geometry (rsuarez1982, o-review)
Gascans have different frame geometry (@Zax, Paul MCJ, O-review.com). Lenses are have a different Base Curve (@kingphilbert, O-review.com). The lenses are much shorter than standard gascans (aLAthing, O-review.com) so they won't fit (BronzeT, O-review.com). Nosepiece is deeper and flatter. Some of the different models were - brown smoke/gold clear, dark olive/black clear gradient, polished white/warm grey (jbigelow, O-review.com).
Goggles have an extra pad at the nose region
