Answer:
A bee has five eyes. There are three, called ocelli, in a triangle on the top of the head which are really only sensitive to light and dark and don't form images.
The bee also has two compound eyes, one on each side of the head. These form images, though not as finely detailed as our own eyes, more like a mosaic. This type of vision is very sensitive to small movements.
The bee's color vision is also different from ours. A bee can see well into the ultra-violet part of the spectrum, which is invisible to us, but is not so sensitive at the red end of the spectrum, so to a bee deep red appears as black.
