I had these off and on over the years, and they somewhat seemed associated with stress, lack of sleep, to much/to little coffee etc, but recently they became more and more frequent. To the point of having them every couple of days. However, getting eyeglasses has dramatically reduced the occurrence. I hadn't notice I needed eyeglasses, I could see things just fine, but apparently one eye is quite a bit worse than the other, and my brain was just doing some extra processing and making everything look OK. Eye doctor speculated that this extra processing was the cause of the ocular migraines. Now, whenever I start looking a screen to program or whatever without my glasses, I can start feeling the impending tension building towards a migraine, and unless I put them on, will almost inevitability get the whole ocular migraine experience, and be useless for the rest of the day.
