The only problem is how do I make the Lens reflective.  I wish I had a texture artist to lend a hand.  

Saw this at the LW Forum, as well.  Why not add a cornea?  What I do is simply copy the eyeball to another layer, make it uniformly smaller, keep it labelled as eyeball...cut it and paste into the figure layer, click on the larger version, select all that mesh and control q, label as lcornea, etc..  Then, pick out a nice reflective glass material.
