I think the appearance due to side lighting is from total internal reflection, like what happens in a prism.
Light entering at a shallow angle to the iris goes into the cornea, hits the other side of the cornea, and bounces down.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
