Water is relatively opaque at wavelengths above and below the visible spectrum. Air is also much more absorptive outside of the visible range. These two effects compliment eachother - water has a very sharp increase in opacity in the ultraviolet, while air has a sharp increase in the infrared. Our eyes are full of water and we look at things through air. Coincidentally, the visible spectrum matches the peak output from the sun. While you can go a little further into the infrared and ultraviolet ranges, there simply isn't much more to see, it would be as if we were looking through muddy water and dimly lit fog. Any mutation allowing you to see these wavelengths would convey no advantage.
