I'm using feet, (so that'd be between 3.0-4.0 if you're using inches) and I think I just figured out another part of the problem.

 

I'm using 8 bounces with the lens.  I turn off transparency on the EyeSurface mat of viki and the problem goes away.  I tried turning my render setting up to 12 bounces (the max in 7 which I'm using ATM) and the problem is still there.

WARK!
