Cat eyes aren't easily defined in these terms; the structure of their face
and eye means they find it hard to impossible to see immediately under their
nose or in front of their face, outside of those few inches though they have
good vision over a short distance, so technically would be short sighted.

Their eyes aren't really built for general observation like ours though,
they're built to detect movement, so movement which is further away than
their "relaxed" vision (such as the cat across the road) will be picked up
and locked on to; you know it's happening if their pupils suddenly dilate.

Try this; next time your cat is sitting somewhere suddenly produce their
favourite piece of string or toy and start flicking it around; watch their
pupil really closely, even on a sunny day when the eye is normally a slit,
producing "prey" triggers the hunting instinct; ears shoot forward, pupils
dilate to let in as much light and information as possible, tail starts
flicking, they're like some amazing hunting machine.

It's thought cats can see in colour (certainly blue and green), they can
also see exceptionally well in bad light; they can't see in complete
darkness but their amazingly adjustable pupils can expand to cover most of
the visible eye and let in every last scrap of light available.

I expect with cats as with humans though, some will be a little long sighted
and some a little short sighted so there will always be exceptions!
