Ray It is hard to make diagnoses over the internet, but it sounds like you may be having corneal surface problems rather than true double vision. You are seeing two or three overlapping objects, sometimes clearing with a blink or two but sometimes worsening? You get blurred when you do any sort of visual task for more than a few minutes? Your eyes feel tired, gritty and sandy as if you had something in them? These are symptoms of dry eyes, very common in PD, and exacerbated by decreased blinking and blepharitis [inflammation of the eyelids]. It can be remedied by warm soaks, lid scrubs, frequent application of non-preserved tears and several good blinks every time you think of it.
