The light may not exactly flash but it moves along the side, front to back, of your peripheral vision in one of your eyes. Also, does anybody else get it when you change to light or darker settings? For example, If you walked from a brighter to a darker section of a room, or if a large piece of hair suddenly falls near your eyes and blocks light.
i do... not flashing but a 3 (almost triangle) dots in the left center of my eye that last only for a second or less.
I used to see different colors in my left peripheral before my brain surgery took away peripheral vision
Yes I've had it on &off for many years (not the same as the zig zag visual disturbances during a migraine)I wear glasses &have my eyesight/eye health checked regularly ,they say my eye health is fine
