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.
