It can be an indication of a stroke in your eye. My friend had an explosion of light before bed and he woke up blind in one eye. If you think you physically experienced that you may want to see a doctor.
@JoyfulSilence That's interesting. And it's weird, I see clear spots (particles? not floaters) that bounce around when I look at the sky...not sure if that's related or something completely different
See an eye doctor. Maybe they will see something and can treat it.
------ As for me, I have diabetes and got floaters. They said the high sugar damaged my blood vessels in my retina and they started leaking. It is a common ailment of diabetics. The body also responds by growing new vessels which can cause problems with vision, even blindness.
I got laser treatment to zap them, and am now getting shots of a drug into my eyeballs (!!). The doctor says they are working. My swelling is down, and floaters are fading.
My doctor also said I am developing cataracts, so I suspect someday I will need surgery to clear those.
