RE: (meteorobs) FOV and Catatonia
The "flashers" or Floaters that you experienced are caused by streaming and
bubbling of the vitreous humor of the eye catching incident light. Floaters
are a normal phenomena that occur with age. As your eye moves they will
track with the movement and can sometimes appear as fast streaks. I am a
victim of them too. I thought I had a cataract until my eye doctor explained
what was happening. I see them when I get fatigued also. Many faint flashes
I see, I have trouble determining if it is a true meteor or just a flasher.
If I can't decide, I discount it.
