Blurry vision is a symptom of PV. Also, dry eye can be a problem which can cause blurry vision. Some days are better than others for me.

I do believe keeping Red blood cell counts in normal range helps.

I have trouble with my eyes and it's hard to explain. It's so hard to get my prescription right.

Hi Marian
Just had my appointment with retina specialist. I’m having blurry vision also. Now taking prednisone drops. Don’t think it can get much better. But hope so. And for you also.
