Have you ever taken a closer look at your cats eyes? The front of their eyes are flat! You can especially see this if you look at your cat’s eyes from the side. The eyes are round just like us, but the iris doesn’t follow the shape, behind the transparent layer the iris is flat!
Google doesn’t know the answer, but Tom & I got a few theories.
Why do you think the iris of a cat would be flat?
It probably changes their depth perception in some way. I’d imagine it’s not just the iris…you know the pupil and everything as well… I have noticed that before too though
The Human Iris is flat too.

But the human iris looks different. It looks to me like its going with the rounding. Or the space between the retina and iris is bigger than with ours?
Looking forward to the answer!
So am I.
Still a few theories! No clear answers yet.
But I personally think it has something to do with light, like Spiders said.
I did not knew this, nice insight!
I had a cat once whose iris came OUT in an odd-shaped bulge. Asked the vet about it and he said it wasn’t a problem for the cat, but he was impressed I noticed (I was about 14). I would think flat or even slightly concave would help direct more light into the eye?
Huh, an Iris that came out in an odd shaped bulge? Never seen that before!
The iris just cuts off the light except at the center of the lens, like the shutter of a camera. The lens in both does the focusing.
Ah, thanks for clearing that up!
I don’t know if the iris is flat, but I know that the lens is, it lays under the iris and breaks the light. My theorie on this question is, because his eyes can give light in the dark, they lighten up, it’s a reflection.
Lenses that are flat do not focus light.
