It seems that you have 2 problems. First, you have daily flashing lights. Second, you have unnecessarily frightened yourself by reading on the web about conditions that may not apply to you. Have an evaluation by a retina specialist. You can find one at www.aao.org.
* I should also add that the eye doctor told me to return if I see flashes that are like fireworks and are like that for 20 mins or more . My flashes are throughout the day not many but they do occur.
