The peripheral vision in my left eye has been blurring or becoming distorted. It isn't constant, but sometimes I notice it warping mildly and revert. It's almost the same visual sensation that occurs as if I've just rubbed my eyes. I also find that I only get headaches on the left side of my head. My vision also fades when I stand and I can hear my blood pulsing in my ears when lying down. I only mention those because I'm not sure if they're related. Mostly concerned about faded vision!
