Hi ok you might want to try a vision therapist. A vision therapist is an optometrist with the added credential of Vision Therapy. Ophthalmologists by the way, don't believe in it. A few years ago, I was experiencing light flashes (differently than what I experienced a few days ago, in shape and location, but nevertheless similar), and I sought out a vision therapist with great reviews. She fixed it! She did tests and then gave me exercises to do and it went away in about 6 weeks. But, just to make sure, the week after I had seen her, I had gone to an ophthalmologist retina specialist who just said that my eyes were fine and he had no idea what it was.
