Hi. I have had this issue for years upon years. As long as I can remember. In the absence of light I see a semi swirling kaleidoscopic tydish color scheme overlaying in a gradient that corresponds proportionately greater with the decrease of light. During the day it just seems as though there is clear TV static in the air. I have also had a singular non migraine headache in the crown section of my forehead only from temple to temple. I have had mris pet and cat scan eegs seen neurologists optometrist (kinda) aroma therapist ents alergists and the only thing anyone ever said was in jest that maybe it's a stigmata. Personally, not accepting dogma as a diagnosis and since glasses didn't help that rules out eye migraines without pain, correct? What POSSIBLE thing have I overlooked besides Charles Bonnet syndrome or additional senses that have faded from common use?
