Hey now..... I wasn't trying to disregard your issue or be a jerk to you. I just misread your post and if you did see the sparkly flies, try to make you feel better.

The only time I can relate to that is during strenuous exercise. For example: I played ice hockey a few months ago and when I got off the ice, I looked down to the ground, while sitting on the bench, and notice that the ground flashed a few times, then when away. When I looked up and back down, I noticed the same thing. It was in the center of my vision. It went away after sitting there after 5 minutes or so, but strange to say the least.

I have also noticed this when starting at the TV or computer too long at night, with the lights off in the house. When I turn off the TV and close my eyes to go to sleep, I notice in the center of my vision, this constant dull flashing. I have noticed this ever since I was young, so I really don't think what I experience is a problem.

I have no idea if this correlates to what you are seeing.. just trying to help. If not, I'll delete my comments and maybe someone else can relate to what you are seeing.
