Is it normal to see a glow around a light source.

If I get under a street light and look up, the thing will blaze like a
sun, an intense glow radiating from the bulb.  I wonder if this is
what they describe as a visual halo, but then I wonder if it's
completely normal, I mean it is bright.

Same thing happens in some headlights, especially when they're coming
straight on.  Only head the glow is usually a million lines pointing
to the light, or the glow is composed of little blobs (kind of like if
look at a light with your eye tearing, only here the blobs are much
smaller).

Lastly, if I look at the chandalier in my dining room, which has very
bright lights, I see the smae glow/starbust, only here it is
accompanied by a shimmer.

Normal?

I thought it might have something to do with my astigmatism/myopia.  I
know my prescription is a good diopeter off (right now around
-6.75.).  Sure enough, if I tilted my lenses, increasing the
prescription or so I figured, the glow would sometimes assuage some.
But not all the time and not all the way.

Then I thought floaters.  I have pretty bad floaters, and one good eye
which means the floaters are augmented because there's no other eye to
compensate.  Sur enough, when I flicked my eye the image would
sometimes dramatically imrpove as the floater scooted past.  An
improvement but there would still be that glow.

Then I thought that perhaps the glow was to some degree normal, it was
just that the floaters/refractive error was augmenting it.  But it's
so hard to tell because I don't know what other people see.
