I have been experiencing moments when my vision seems to cloud in one eye with just a square of light I can see through in the middle. This doesn't happen often but when it does it is difficult to see out of the one eye. It is accompanied by a strange sensation as well. Not really dizziness just sort of like pressure of tiredness behind my eyes. At times my vision to the side of the same eye catches what seems to be best described as something crawling up whatever is about 2 feet to my side. There is nothing there when I turn my head.

So, why have you not gone to a professional eye doctor for an exam. There are many reasons that can cause this. Some if caught early can save vision, others if you wait too long can not be.

On top of that this sounds like it could be neurological in nature. It could be a sign there is something wrong between the eyeball and the brain or the brain. Please get it checked out.

I agree... I would have ran to the doctor the first day I had those symptoms. I would never do or NOT do something that would even have a chance of Impairing my vision. Maybe the fact I've worn glasses since grade school makes me more aware of the preciousness of vision.
