Sorry, when I read what I wrote I realized I wasn't thinking.

The image of you in the baby's eye is about 4 mm behind the cornea.

The image you see of the iris is about 2 mm behind the cornea.

The difference is about 2 mm.

You do not see any image on the corneal surface.

A refected image should focus at the distance from the camera to the eye + the distance of the eye to the reflected object. In this case, twice the distance from the camera to the eye. You can test this by aiming the camera at a mirror and focusing on the camera. The distance scale should read twice the distance from camera to mirror.

Since he shot the image at f/4, I don't know why the photographer is so sharp.
