Suggest Remedy For Eye Disorder

Out of no where I am experiencing a black kinda oblong fuzzy like shaped ring, kinda like a halo, about the size of the tip of my little finger, ( I wear a size 3 or 4 ring on that finger,) symptom in the vision of my right eye. It is not just in my peripheral vision..it moves when I move my eye, from a little off to the right of medial to far peripheral vision. I have never experienced it b4. I can see through the center of it. I thought at first I had like a fuzzy thing attached to my eye or to my eye lashes that moves when I move my eye. I am 62 years old and recently had my eyes checked with a normal vision diagnosis. I am not a diabetic, and have not been under any stress either.
