Great info. Thanks for sharing. Knowledge is always good.
I've seen the theory that orange eye means blindness or eye problems, however to my knowledge no scientific study or electron microscope examination of anatomy has ever been able to substantiate this. There was a student of macrobiology last year that corresponded with me trying to prove/disprove the theory, but his research got yanked before he could finish it.
Regardless, I love the light eye look. I have had yellow, green, brown and black eyes in my neos.
