oh, that's a separate thing, maybe somehow related but i don't think so... i used to get it often while dehydrated and from too much energy drinks, can't see properly in the central part of my vision because all these patterns are blinking in and out

no, double vision is from the neuromuscular dysfunction, normally there is a twitch where the eyes move slightly left and right or something like this, but with this happening they are out of sync and don't converge properly, so you get double images, like looks like ~1mm double image of everything, makes text really hard to read, and computer screens especially ones with slow refresh like 60hz the pixels even paint in the wrong position as well as the double vision

i was worrying at first when it started happening last year that it was Wernicke Korsakoff, a disease often associated with heavy alcohol consumption but i'm not actually quite *that* bad and what actually was causing it was artificial sweeteners and stuff like maltodextrin and high fructose corn sugars

the visual migraines are hell though... really can't read at all... the double vision, that's bearable at worst you just increase the size of the text and you can read ok but as i have been resuming carbs in my diet it's coming back worse so it seems like the only way out is milk/carnivore
