Maybe this will help: https://visionsimulations.com/visual-snow.htm https://visionsimulations.com/visual-snow.htm Although the condition is not well understood, I think the consensus of opinion is that the phenomenon is neural rather than opthalmic - i.e. perceptual in nature. If you are perceiving entropy in a similar way to the website I linked, it could be VSS (obviously you should consult a medical professional for a proper diagnosis though).

> Maybe this will help: https://visionsimulations.com/visual-snow.htm https://visionsimulations.com/visual-snow.htm Isn't that... just entropy? At least, the default settings. Like... that's almost what I see (on the website it is greatly exaggerated). I see it because physically, light literally doesn't take the same path twice. Exact same reasons why path tracers take a long time to converge. I can see solid colors and make out shapes (even very small shapes) easily. Nothing is obscured. The noise isn't obnoxious or distracting or annoying. Neurologically I smooth it out and perceive a world without noise. But it's there. I would be more surprised if this is not a thing that happens to everyone. If someone can look at a surface, and see a completely solid color, with no sign of noise at all ever. With no entropy or anything. Completely and totally static and unchanging.

  However you describe it, that's not how I experience vision, and as far as I know, not typical. If you've had this all your life then it's reasonable that you would assume everyone's vision works like that; maybe you could try using that website to compare your experiences with some friends and find out.

    > If you've had this all your life then it's reasonable that you would assume everyone's vision works like that I just can't possibly imagine vision that has zero noise at all. That can't be physically possible. Surely people who think their vision is completely 100% noise-free are just unable to tell that it's there? Or am I just crazy? I mean this is literally the same reason why photos taken by digital cameras have noise in them... > maybe you could try using that website to compare your experiences with some friends The website just isn't accurate to what I see for some reason. It's not nearly that obvious. It's just how solid colors are constructed. I'm fairly sure that everyone has this and just doesn't notice. But... "fairly sure" isn't completely sure. I would be so surprised if I'm wrong, but I have no idea, honestly.

      Only just saw this, sorry - you'll have to ask around I guess but no, I genuinely do not notice any noise in my vision even if I really concentrate, except possibly a little at night time. I think for most people, the noise is filtered out by the brain, but that's perceptively equivalent to a total absence, which is what I experience. There other effects like persistence of vision - staring at anything for a long time will create strange visual artefacts but I don't think that's what you're referring to.

I think for most people, the noise is filtered out by the brain, but that's perceptively equivalent to a total absence, which is what I experience. That's... really weird. For me it's everywhere all the time, especially in darkness. I filter it out... subconsciously, or something? but not perceptually. It never distracts and never obstructs but it's never just genuinely missing. Could be caused by being autistic, I know autistic brains can be bad at filtering out stimuli. > There other effects like persistence of vision - staring at anything for a long time will create strange visual artefacts but I don't think that's what you're referring to. That's indeed not what I was referring to, but I do also get this. If I stare at something even for as short as 10 seconds, and close my eyes, some "impression" of it will stick for a few seconds. Usually just the edges or vague layout of it, and faint enough that I don't notice it unless I try to trigger it on purpose, but it's there. And if I stay perfectly still for long enough, everything will fade to grey until I move my eyes again. But both of these have no effects on the noise.
