I haven't played with the software for a while now, but I believe you
use center thickness on a lens and the software takes care of the
curve.  When last I used OSLO LT. it did come with a few sample files. 
Like I said in my last post, even making simple changes to them wasn't
intuitive.  I would suggest you down load the software and take a look
at the sample files.  I'm sure there is one in there for a lens.
