The latter would be the usual way to go though.

Another approach would be to place the camera inside a transparent 
sphere with ior, and add an averaged texture in front: One (stronger) 
sub-texture being totally invisible, the other (weaker) sub-texture 
having high-frequency perturbed normals. To be used with strong 
anti-aliasing or focal blur. However, this approach is only useful for 
creating halos around exceptionally bright objects.
