if you are using, eve,with the real eyes prop, it is the cornea, that needs to be made transparent. i forget which of the eye parts off hand for posette. anyway, in bryce, use one of the other camera views and get zoomed right up on her face, and use the ctrl click method to isolate each eye component and monkey around till find the right one. all you usually have to do is go to the material editor, turn transparency on, and choose blend transparency from the pull down menu, for the cornea and the eye colour will return.
