    What’s Visual Snow Syndrome (VSS), and why do so many autistic people have it?

    I learned about this the other day, when I posted about palinopsia (visual trailing/afterimages) being common in autistic people, and a couple of our followers told me about their VSS. I did some more research, and discovered that I also have it.

    Visual Snow Syndrome is a neurological condition that interferes with visual processing. It’s caused by hyperactivity and hyper-excitability of nerves in certain areas of the brain that process visual information.

    The core feature of VSS is constantly seeing tiny, fuzzy “feedback” in the environment. It’s kind of like seeing the world through a staticky TV screen. Some people’s visual static is larger than others. Mine is relatively fine-grained, but it gets bigger and more obvious in low lighting.

    Some of the other symptoms of VSS include:

  • Palinopsia (visual trailing/afterimages)
  • Photophobia (sensitivity to light)
  • Increased and enhanced ectopic phenomenon, such as floaters, phosphenes, and Scheerer’s phenomenon
  • Seeing glare, starbursts, and halos around lights
  • Difficulty seeing at night/in the dark
  • Seeing random flashes of light and/or color, without cause from the environment
  • It’s common for people with VSS to experience comorbid migraines, but VSS is not the same thing as migraine aura.

    So, why do autistic people often have VSS?

    It comes down to the fact that VSS is caused by the hyper-excitability of neurons in areas of the brain that process visual information. A core feature of autism is hyper-excitable neurons, especially in areas of the brain that have to do with sensory processing. So it makes sense that autism would often inadvertently cause VSS.

    Here are some illustrations of visual phenomenon that VSS causes, in case you want a better understanding of what the world looks like for me and many other autistic people.

    I hope y’all have learned something :)

    I’ve found it very intriguing to realize that the way I see the world is more unique than I once knew!



    WOAH WOAH WAIT DOES NKT EVERYONE SEE THE WORLD WITH A LIL BIT OF TV STATIC?? Like it's subtle so I dont notice it that often so I figured everyone saw it but nobody ever commented on it bc of how subtle it is?? is that not the case??


    I get floaters and the light starbursts. It makes it difficult it drive at night, ESPECIALLY when it's raining!


    I will have what she is having


    She enunicated this SO PERFECTLY and completely in a single tweet. A whole informed essay in a single tweet. Your fave could never!


    Same problem we have with cops. Police are more likely to have certain characteristics and personality flaws not because becoming a cop makes you that way, although that may amplify the effects, but rather, men with these problems gravitate to the position. That’s why so many bullies end up becoming cops


    You pointing out the cops means I need to point out; Female bullies tend to go into nursing! A position that puts them in power, and gives them control over people. If you knew a girl in highschool who was just an awful human being but thought she was great? Chances are she went into nursing.


    Alexandria Ocasio-Cortez pointed out that many young people are concerned about having kids because climate change will make the planet increasingly uninhabitable.

    Fox News hosts are now claiming she wants to “get rid of children.”


    Fuck fox news bro. Rich people playing dumb to influence poor people to be dumb


    There’s hardly been such a blatant and clear example of how biased media outlets twist things… this should be in a damn text book on propaganda


    Her: kids are scared about the future and wonder if they could have a family with how terrible the world is

    Rich ppl: sounds like communist China :^/
