I had the same thing begin about 6 months ago. major floaters and what looked to be a tiny ball of light slide across my vision 4 to 5 times a day, sometimes even more. The Doctor was amazed to find I did NOT have retenal detachment and could give me no explaination. I can't say for sure it is connected but I began a parasite cleanse of humaworm about 3 weeks ago. After the first week, my flashes stopped completely. Haven't had one since.
I had orginally thought maybe the flashes were due to extreme sinus pressure, not to say they weren't, but either way, mine are gone.
