Which display engine are you using, SreeD or OpenGL?  If you right click on the Preview window, the menu will show the display checked off.  Select the other setting.  The whiteness in the render might be the lack of reflected environment in your scene.  The eyes are just responding to your lights.  Are you using raytracing in your lights?

BTW, all the experienced users in this forum use the advanced tab of the Material Room; it shows us much more details about your material setup.

Okay... TOTALLY not a big Poser user, I'm finally FORCING myself to use it because I always shut it down and crank up Daz Studio... I don't want to, for once I want to make up for lost time using Poser... and I'm determined. BUT - my experience of it's ins and outs are limited. Such as what you just told me to do... I thought... HUH? What does he mean?
