Visual Snow Simulator

[Yeshuasdaughter]

I found a website the other day that simulates what it's like to have visual snow. It has photos of different places, and you can play with the visual snow to increase or decrease its density, speed, and grain size.

Very cool. I always wonder what it's like for people who don't see it. It's so hard to explain to them.

 

[Raggamuffin]

Visual snow plus eye floaters. As if my mind wasn't busy enough, my vision is too.

Yep, I sometimes have grainy vision like one of those 16mm movies

If you mean things in eyes I see things float around and when I close my eyes I see red
But my eyes are probably just adjusting to the light. I so have floaters and black floaters I notice

I thought you were talking about Christmas and visual simulations of snow, last Christmas I put fake snow everywhere but it gets messy and bad for the environment but I bet a white Christmas is really nice.

It sometimes can have speckles and flashes of light in addition to the "grainy" or "pixelated" visual field. It is there with the eyes closed. It is there while dreaming.

For those that are born with it, it appears to be a corticothalamic dysrhythmia, they can pick it up on ECGs of the brain. It can also be associated with tinnitus, as the visual and auditory processing centers are located next to each other. Within the context of autism, this is most likely due to aberrant neuronal migrational patterns when our brains were developing.

Ok cool, I do not have that that I know of. I just see things normally but do experience syntheisa
I can visualize things and smell things in music and visualize books.

I have always had visual snow syndrome, but until just a few years ago, I thought it was normal and everyone had it the same. It was quite a shock to learn that it was not "normal" and most people do not have it.

I have also had "floaters" since forever. I can't remember ever not having them. I remember sitting and watching them float around, trying to follow them.

Interesting! Since learning that visual snow syndrome is a thing, I always considered it visual tinnitus - which I also have.

I don't really know, because I don't know if what I experience is normal. I do get a kind of graininess, but it doesn't impair my vision.

No, it doesn't impair your vision, per se, in the sense that it makes things blurry or out of focus. The ability to focus is within the lens of the eye. The visual field associated with Visual Snow Syndrome is caused by abnormal visual processing.

I have VSS and thus I see it on the "normal" picture too, but to a lesser extent.

 

[FayetheAspie]

I have a mild form of this symptom. It goes almost entirely away in bright outdoor lighting but can get fairly thick in near total darkness. I do not think it connects to my autism at all because I was several years old before it started. I think it was a delayed reaction to a minor head injury.

 

[Harmonie]

I have experienced this for many years now. I never had a word for it. I always called it "grainy", like light static on TV over the show.

Coincidentally, this is one of my favorite sleep sounds to listen to on hot nights.

I remember having this as early as being a young teenager and it has been persistent to the current day. It seems more noticeable in darkness, but is generally there all of the time in my visual field.
