By 2d planes, you mean that there are no eye sockets concave from the rest of the face? Generally 3d models have holes cut in the face mesh, concave sclera meshes, and the pupils as floating circles in front of them.

Ok, you cut out the holes, now cut down the meshes to just a circle of the pupil, and add cups for the sclera behind.
