These are called ocular migraines. I’ve had them since a kid, roughly once every two months or so. what’s really interesting is after having heart surgery, I would have like 10 a day for weeks. Others in post-cardiac surgery message boards reported the same experience. It went back to normal frequency months after surgery, but definitely an unsolved mystery!
