I didn't notice that the iris was out of round. I noticed that if you
look at an angle through a hole in a plate of finite thickness you
will see that your line of site is neither round nor elliptical. Part
will be masked by the front surface and another part by the rear. The
result is a field of view shaped like a (non-soccer) foot ball.
