My wife and I have had this debate for months. She is in optometry school and I know I shouldn’t debate in her area, but I just can’t concede this one:
Cat’s pupils are usually slit-like, like this - () () - not round like human pupils. So does this mean they can see further up/down or left/right? My wife says up/down since the slits are letting more light in from the vertical field of view, but I say left/right because cats would need to see along a wide field of view when hunting (like lions in the wild on the planes) and up/down wouldn’t be as helpful.
So who is right?
