I've been seeing a small grey/black spot as my eye move but it does't drift away when i look at it directly and it is always there when i pay attention. Sometime it turn flashing light and spinning light ball and i can see it even when my eyes are closed.When i focused it for a long time in the dark,it is spinning and getting bigger and bigger and the stable.Is that macular degeneration or scotoma?or it's just flashing light .I've worrying about it.I also have few floaters but not black/grey.
