What could cause sudden blurry spot in vision?

What would cause both of your eyes to feel a lot of pressure and see lots of brown 'floaters' for a few weeks then have only 1 'floater' in one eye with blurry vision and dryness in that eye for days?

• Answer:

  Glaucoma causes an increase in eye pressure, but one doesn't usually notice it ... http://www.ahaf.org/glaucoma/about/symptoms.html If you are still having problems I urge you to call an eye doctor as soon as possible. Although it might be nothing to worry about don't take unnecessary risks by delaying professional consultation. It's possible you may have 'dry eye' and need to see a Ophthalmologist for a proper eye exam to be sure you do not have a Retinal Detachment. http://www.richmondeye.com/eyehealth_eyelid.asp Seeing floaters (even children as young as 12 can have this) that can be sperm shaped; brown to black spots gives the appearance of dark specks in the tear film of the eye. A dysfunctional meibomian gland are likely to have this, but ocular allergies or even wearing contact lenses can cause this problem. To decide what can identify from the two the individual can quickly blink and the debris in the tear film will move quickly with a blink while floaters are unresponsive. Only an Ophthalmologist can detect a true diagnosis.
