The blur you see in Mass Effect 2 is called Depth of Field. You see it with your own eyes, but your eyes automatically focus on what you want to look at, so you don't really notice it. Depth of Field is used a lot in cinematography, focusing on the speaker in either the foreground or the background for example. I've seen it used to OK effect in games like Gothic 3, where very distant land, that is less detailed due to LOD having a blur effect to simulate depth of field. This has the odd effect of simulating a condition known as Myopia, or near-sightedness.
In screens I have seen of Skyrim so far, it does not use a depth of field effect. You are, however, seeing atmospheric scattering, where the further away something is in a scene, the more the atmosphere "scatters" the light, giving distant landscape the impression of fading into the color of the sky.
