I believe that some medications affect vision.

DeeJack: I am not sure about PH effecting vision, but it is such a powerful illness , until "NO ONE REALLY KNOWS"..... PS. plus "ALL" of us are different & we will probably have different "SIDE EFFECTS"..... Just hang in there and keep "HOPE ALIVE"!!!!!......

I'm not sure, but my echo and my vision were both worse this year

I don’t know either if it affects one’s vision. I do know I’ve noticed that my eyes get tired and blurry when I read for a long time .

I don’t know if PH affects vision but I find after I read for a while my vision becomes blurry. My PH is diagnosed as moderate. We are all different and one’s problem may not fit another.
