Technically, yes. "Astigmatism" literally means "lack of a point."

In common usage, though, it's assumed we mean _regular_ astigmatism, a
smooth surface, slightly bent more in one direction and less in the other, a
"football" shape.

But in real life, not all astigmatism is "regular". Look at a corneal
topograph and you'll see steeper and flatter areas, hills and valleys, that
aren't entirely correctable with lenses.

Theoretically, wavefront-guided LASIK could give permanent relief, but it's
expensive and drastic for such a subtle problem. Most surgeons would
probably not want to attempt it.

Rigid contacts (or perhaps even soft lenses) could improve the problem but
only while you wear them. Rigid contacts used to "reshape" the cornea could
give more lasting results but that treatment is somewhat unpredictable and
expensive.

The most practical treatment is glasses, prescribed late in the day. That
won't give perfect results but will probably reduce the appearance of double
vision when you need it.

If your doc doesn't find clear evidence of a problem and can only
speculate about unappealing treatments, there is a possible simple
alternative you can test yourself.  These descriptions of come-and-go
cloudiness and multiple images are something I also get from time to
time, and can snap out of it by covering up the "good" eye for an hour
or so.

I forget the tech term for the problem... something about poor
binocular coordination leading to your brain tiring of resolving the
two images and  just giving up the fine tuning of one of your eyes
focus.  A vernacular term used to be lazy eye, and you would see kids
long ago with an eyepatch (over good eye) to correct this.  The
underlying problem of the bad eye may be negligible and you might work
on just stopping the shutdown once in a great while.

My doc used to treat this with eye exercises, including using prism
glasses to intentionally seperate the images.  A simple approach is to
close one eye while watching TV for a while, but it doesn't work well
straining like that in a passive environment.  Rather cover the good
eye in some comfortable fashion and do a (safe!) task that requires
some medium distance acuity yet takes your mind off your situation.
You may find a 15-30 minutes later, POW! things snap back in perfect
focus, but may want to do it longer or the good results may be
temporary.  I have to do this sometimes twice a year, and there is a
lot of possible speculation about underlying reasons, but on the other
hand the solution is so darned simple...
