In brief: Depends
Your age, past eye history and an exam would help with the answer. If you want a list: cataracts, acephalic migraines, refractive surgery, bad contact lenses, corneal edema, iritis, posterior capsule opacification are a few on the list.

In brief: Beware of glaucoma
There are literally thousands of potential causes of blurred vision, but not so many for halos.
If what you see is like looking at a streetlight through a frosted window, that is a true halo. It is often caused by water mist between you and the light. It can be seen for a while following eye surgery such as lasik. It can also be caused by acute glaucoma, so your eyes should be checked.
