Dolphins' eyes are on the sides of their heads, and the eyes can track separately, which human eyes mostly can't. However, in other ways their eyes are not too different from humans. It appears from recent studies that their brains process sight information in much the way ours do - taking information from both eyes and creating one main image out of it, made up of many layers of images piled on top of each other. It would be much harder to describe insect vision than dolphin vision - I'm just picturing it as very sensitive to changes in light, capable of seeing more with less light, and about 300 degrees of visibility.
