Hopefully this hasn't come up before (the search function is gone so I can't tell)

Anyways, given that the o website lists these Gascan lens separately from Asian Fit Gascan lenses, I take it the lenses shapes are different.

Anyone know how big the difference is?? And if its absolutely impossible to us the lenses interchangeably??

It's a base curve difference. I wouldn't interchange the two as the frames are not made to the same curve.

I didn't know it was a base curve difference. I thought the asian fit gascans just had a shorter lens, which meant they wouldn't fit at all into the regular gascans.

I've never tried it, but if they do fit, the optics will be 'off' due to there being constant stress on the lens to fit into the frame. I personally again have not tried it.

Guys, thanks... another crazy idea out the window...

The Asian Fit GCs have a much shorter lens than the standard GCs.
