Re: 'Hazy' / cloudy vision ?!?!!?!
Okay, clarification needs to be made here. If you are describing cloudy as observing what looks like steam in the room around you, then depending upon your age it could be due to a vitamin B12 deficiency. If, by contrast, you are actually describing the room as more blurry or less sharp in appearance, then this is more often due to a parasympathetic response that temporarily diminishes accommodation. It can become evident more often for persons who work long hours at a computer, seated in a fixed position and then quickly move their gaze from the computer screen to the room about them. Most often, objects in the room appear soft and blurred to a slight degree and it's due to a latency in the ability of the eyes to accommodate between near and far objects. This tendency increases with age as well.
It is seldom a sign of disease.
