I’ve also had ocular migraines for years, with no headaches to go with them, thankfully, altho I probably just jinxed myself. Mine have an area that becomes out-of -focus along the ‘inner’ edge of the visual as it starts small and gradually expands until it’s beyond my peripheral vision, which be disconcerting at times. The flickering, glittering, colorful arc almost has a rod and cone aspect to it.
