  I didn’t realise these were white blood cells. Thanks for the read.

    I believe this is another related, simililar, yet technically different phenomenon, with different causal mechanisms, but yes, lets keep adding to the list, lol.

    Also, brb, you’ll never believe this, apparently my pizza delivery guy’s name is ‘Hiro Protagonist’, he’s almost here, and I gotta ask him what is up with that name.

    Visual snow is different, it’s constant and looks more like tv static or film grain, fun stuff, not.

  You sure you don’t have high blood pressure?

    I mean, now maybe, lol, but I noticed this as a middle schooler, and I was in pretty good shape back then… and I still have the exact same experience to this day, in the right lighting conditions, if I can just sit or stand still and look at a mostly cloudless sky.

  I most commonly see these these when I have a migraine, really bad sneezes, or I flick my eyes or move my head quickly. I’ve heard it’s fine unless you see a bug chunk at the same time as that could be a sign the retina has broken or come loose?

    The dots are white blood cells moving in the capillaries in front of the retina of the eye.

    From the wiki page.

    So, yeah, it makes sense that very similar or even just the same effect can be intensified by all those things you mention, they all alter the motion of blood in your eyes.

    As to a big chunk moving?

    I am not an eye expert, but I would intuitively think that yes, a big splotch moving could be the retina itself moving… but it could also potentially be something like a clot in one of those capillaries breaking loose… which is probably still bad, but maybe not necessarily as bad?

  Always wondered what this was called. 8 get this often in winter, less during summer. Really puzzled me the first few times it happened, I just figured I was getting diabetes.

    Basically, lighting conditions have to be just right to … basically, allow you to actually see your own white blood cells, in your own eyes, against the … background/everything you are seeing.

    So my guess would be that in the summer, where you are, the … ambient light of the sky is too bright, it overwhelms this effect, but in the winter, maybe its mote generally humid, or the light is coming through more atmosphere , at morr oblique angles, and is thus less intense.
