I followed a tutorial on how to create an eye and it had me create the inner and outer layer separately (the iris and eyeball itself as one part and the translucent retina over it as the other part and I ended up joining the two parts, which I suspect has something to do with this weird effect I am getting - and when I mirrored the now single eye on the head (because I joined the eyeball and the transparent retina layer over it) I got this weird white I effect that doesn't make sense to me. Any clue what the problem might be? The nodes in the screenshot are what the retina outer layer had when I joined the inside layer of the eye to it.
