Lyme disease (borrelia) did this to me. The bacteria would form cysts under the retina, and cause areas to be out of focus, or become especially light sensitive and have spots that looked like afterimages. I would also at times get the flickering or flashing you describe.
Lately I've been treating Lyme very aggressively and while this has caused severe herxing, my vision has gotten a lot better. The sensitive spots are much less so now, and I haven't seen any flickering lately. I'm surprised how much it has improved.
Some people on this forum have blamed bartonella for their eye problems, but I found that treating bartonella had no effect whatsoever on my vision problems.
