Description
I always considerd that I had blue/grey eyes. But looking at this and running a dropper over it, there's no blue at all. In fact PS7's colour picker thinks my eyes are green.
Anyone out there who can explain why the iris is so complex? What's the need for such intricate patterns? What causes it? They look like tears in the iris to me. Do Iris's (plural?) rip as we grow? Answers on a postcard.
This has been in the member gallery for a while, so thought I'd post here too.

Lovely image! And... I have NO idea about the patterns our eyes form. Thanks so much for sharing!

You eye(s) do look green, but I bet they also pick up surrounding colors - and so therefore look like they have some blue in them. You have beautifully colored eyes! I guess the iris is very complex because of the work they have to do to keep the level of light perfect for your sight. The eye is an amazing thing. :o)

The pigmentation in irises can actually change over time and is affected by variations in body chemistry and degree of exposure to light. Though it's chemically more complex than this in actuality, basically, three seperate genes determine the base color of eyes; If all three function, the eyes are darker (brown) if only one functions, the eyes are lighter (blue) and odd combinations of the three result in greenish and/or hazel midtones. The streaking in irises is just the striations of cellular structure. Like their namesake in a camera, they have to expand and contract to widen or shrink the pupil according to how much light the eye is exposed to. Oddities and flecks are sometimes in the clear cornea or aqueous humor (liquid) over the iris, or the iris cells themselves have minor abberations that don't hamper their function much. They are complex to be "redundant", so if some cells die, the eye still works. If there was just one muscle and it got damaged, you'd be out of luck. But with the complex irises we have, eyes can sustain numerous cell losses and still work. Everyone's patterns are different just the same way everyone's bones, teeth, hair, skin, and fingerprints are different ... God likes variety. It's actually a good argument for God's existence... NOWHERE in the fossil record can evolutionists point to a "proto-eye". Binocular retinal vision is one of the most complex biological functions in the world, and there are no "intermediate" steps to point to historically in terms of evolution.
