Up close shot of a kitten's eye.

This was actually very hard to do.  As you can see, the pupil is there, but not very well defined.  That's due to a lack of blood flow which is normal.  As the newborns get older, the eyes will receive more blood and become more developed.  Right now I can confirm that they see light, as they close their eyes with the camera flash.  But they can probably only make out crude shapes.

All kittens will have blue eyes up until about 4 months.
