This sounds like it could be central serous retinopathy. There are some recent posts about it so you might wish to put that in the search feature.
You should see a retina subspecialist (an eye MD ophthalmologist) for further evaluation and possible treatment. This should not be ignored.
I've had an arching wave in my vision occassionally with no pain. The specialist I saw said I have occular migranes. Mine will go away in about 30 minutes. Seems to happen more when i'm in strong sunlight.
I am having the same issues, blurred vision in only my left eye. I can read things but they move as if I am reading through water or a glass. My started after having a pretty intense cold then my eye was twitching for about 4-5 days. Suddenly on my way to work one day I felt dizzy and realized it was my eye that was seeing "wavy". I am making an appointment with an Ophthalmologist because I am getting mixed messages between it being stress, a retinal tear, aura migraine or Macular degeneration. I am hoping with the twitching it ends up being stress related but since it has not cleared up since thanksgiving, I'm not giving it any more time.
