Eye flashes result from thickened vitreous gel pulling and rubbing on the retina, causing visual effects that look like lightning streaks or light flickers. These flashes may appear off and on for a few weeks or months, but normally fade over time. If you see flashes accompanied by floaters, you most likely are experiencing PVD. Flashes also can be caused by an oncoming migraine headache. In these instances, the eye flashes often will look like jagged lines or heat shimmers that last between 10 and 20 minutes.
