Is the "eye" of Ra symbol depicting a Vrill parasite entering the eye socket of it's host/prey ? The long part with the curly tail being the parasite and the long straight part the liquid secretion produced by parasite that runs out of the eye socket. Also believe the cross with loop tool (ank?) was used to pull eyeball of host/prey to assist the parasite/worm in entering and wrapping around optic nerve. AKA droning which often leaves one eye of the host/prey a little different.
