I suffer from visual snow and also have floaters. You learn to ignore the static after a while but it is always there if you focus - looking at plain surfaces (e.g. blue sky) makes it very obvious. And as you said, it drastically affects my vision in darkness (think of grainy CCTV footage). I haven't done drugs and don't suffer from migraines which are thought to be correlated. Apparently it is also correlated with Tinnitus but I haven't been able to self-diagnose that.

For the longest time, I wondered if people saw a "static" overlay like I do. Talked to my optometrist about it last time and he wasn't aware of this condition. Googled it later and there is some research starting on the subject: http://www.eyeonvision.org/

Have the same thing (as detailed in my other post to this parent) and i also suffer from Tinnitus. Interesting that some people on HN seem to have the same issues, even if its just for the "i am not alone with this" feeling. You kind of loose faith in yourself if nobody around you, not even the doctors, has ever heard of what you try to explain.

I had no idea this wasn't normal. I might also have Tinnitus. I can't imagine how the world looks and sounds to normal people, must be great!
