You wonder how clear is vision anyway?
I have had visual snow since I was a teenager. I remember when I began getting it. I could see this field of static against walls and in particular it would become more vivid at twilight and at night. Twilight would become this more surreal appearing time it seemed to me with this thicker static making the air seem pixelized. It wasn’t my actual eyes as I had regular check ups there. So I assumed it was reality. Even though no one else perceived it. I had not experienced a migraine yet that I know of. I used to get wicked headaches but I do not know if they were migraines. I do know I experienced corona auras then, so I likely had silent migraines back then so that is likely the cause of the visual snow. And when I began getting migraines with aura, which were quite distinct in my early twenties the visual snow and other persistent migraine auras got more intense.
By the time the migraines became chronic the persistent migraine auras were by themselves pretty distorted and wonky. That makes reality pretty unpredictable in appearance for sure. Lines wobble and shake. Things can shimmer. Heat waves appear. Vortexes come and go. Blots and blobs of light appear and distort. Halos surround light sources.
But today I was downstairs having a smoke… as I am in the process of quitting, this making it harder to smoke so out of my comfort zone. Anyway, it is brighter down there and I was just looking at the blank white wall which quite makes the snow appear quite bright and vibrant in appearance. So there is this fluctuating, pulsing field of snow over the while wall. Dim lighting makes it thicker of course but a white wall… makes it quite clear.
And I had to wonder… what do other people see when they stare at a while wall? How clearly do they see that wall? Do they see the bumps and grooves of that wall? Surely not. I can’t imagine clarity you see. I have no concept of it anymore. It has just been too long. I expect it is like if you gave glasses to someone who has been near-sighted all their life. Bam clarity. I am slightly near-sighted in one eye. It was never enough to need glasses for but if I hold one hand over my perfect eye I can see this slight difference in clarity. But I cannot imagine what it would look like beneath that field of static. That shimmer. I simply do not know how sharp and clear it would be.
I know it would not be Moving though. Because the difference between near-sighted and visual snow is that near-sighted is foggy and visual snow is moving and grainy. So it is grainy vision that is constantly moving. Particles constantly shifting over objects.
Vision though is a range. Some people have exceptional vision. Others not quite so exceptional but still do not need glasses. So clarity is a range. So when people look at a wall it may not be a shimmering, warping field of static… but the clarity of which they see the details of it must range. Anyway it is difficult to really focus on things through a field of shimmering static. You can look, but you cannot really stare or focus, you eyes cannot grab onto it for long with all that movement going on. Like if you try to look at the details within that first image there… tricky, isn’t it?
