So I was just thinking that "isn't it weird that the iris and pupil are round?"
Well, I guess that's more of a query than mere thought. Really though, they're basically circles, and I find that, in general, naturally occurring geometric shapes are pretty rare.
Then I was thinking that no Iris is perfectly circular (some pain-in-the-neck philosophers would even argue the concept of circular), so really it's not a circle. In the same vein you could be like "hey rob. Isn't the human shape just the same. If I show a little man figure, you know what it is, and the degree to which it resembles the actual theoretical human form is just semantics, because no-one, and every-one does (resemble the human form that is)." Then I was like, wouldn't it follow then that the human form is a geometric shape? But then, actual geometric shapes have that whole mathematical equation thing going for them.
Then I thought about water droplets, snowflakes, ferns, pine-cones, planetary bodies and honeycombs.
There's probably more.

For naturally occurring geometric shapes, circles and spheres are probably among the least weird and rare. The circle is the least-perimeter way to enclose an area in a plane, and the sphere is the least-area way to enclose a volume. So there's an energy-minimization preference to forming spherical droplets, sphincters or bags of ocular fluid.
The hexagons in honeycomb are probably based on a similar optimization, like bubbles in a plane.
