Thank you again. I did go to a retina specialist. He said my eye is ok (for now anyway). Come back in a month. He gave me an eye test to use everyday to determine if things get worse. It had to do with holding hand over my eye and noticing what I see by looking at the same thing daily and by keeping gaze straight ahead. If it changes the "perifiral" view, I should see him. Meanwhile my "big" floater (maybe half the size of pupil) it still there and still moves L and R, but it has faded a little after 2 months and is less obvious.
Once in a while I have new floaters (tiny dots - like a period). I get flashing light frequently in my side vision. Usually when I drive into garage and look hard to R and L when I am parking. That seems to be the only time.
