Yikes, Don't delete the eyeball! The part that is coming out white is the "outer layer" of the eye that the other three parts fit into. You have an Eyeball, Eye White, Iris and Pupil. If you select each mesh separately in Bryce the Eyeball is usually L or REye_1_1. Select just this mesh for left and right eye and apply a thin glass texture to it. Turn down the reflections to 1 or 2 and turn up the specularity a bit. This will give you beautiful Vicki and Michael eyes in Bryce. You can even save that texture as a preset for the next time you import Vicki. Deleting the Eyeball is a cop out fix and you lose much of the depth and detail you would otherwise get. On another note, don't forget to add the Transmaps to your eyelash and eyebrow textures too. Good luck.
