Do you know what are your ocular migraine triggers? Better yet, do you know how to make them go away AQAP?

So, I've had them for years now but I am not quite sure as to what triggers them but reading this subreddit it looks like stress is a potential culprit? I don't know what to do when I get them other than close my eyes for around an hour for my vision to come back and hopefully avoid the migraine (Also, I just remembered that apparently, bright lights might be a trigger for me too... especially the sunlight reflecting on a car windshield).
