Both! Google on "chromatic aberration" and you'll get an idea of what's happening.

Could you be a little more specific? Under what conditions are you looking at this something very very carefully?

chroamtic abberation is when the outer edges of a lens refract light, like a prism, so maybe that is what's happening with your eyes. i think this has something to do with imperfections in the lens shape.
