how far out does the eye come from the face for the skin to overlap?
that's a matter of personal genetics, some people have eyes sunken in, others have them very protruding...take asians for example, generally they have the eyes more into the sockets of the skull thus a heavy crease doesn't form. you have to take into account the shape of the eyeball itself also, it's not a perfect sphere, the cornea forms a hump of sorts...this kind of information would involve studying races & their facial features
a very good book on drawing faces in general is Burne Hogarth's "drawing the human head"
you can usually find the book for free on e-libraries since it's been out of publication for some time
