Thanks, got it. 
Oddly, this is yet another one that inexplicably expects the user to do some of the math. It also does not allow the user to determine the vertical offset but instead imposes a fixed "optical center".

Does anyone have a universally accepted definition for the phrase "optical center"? Googling the phrase only results in a sea of Optometrist web sites. Wikipedia also has nothing.
