I think MOST of you don't actually have visual snow

OPINION POST

Seeing "snow" in the dark and on flat surfaces is not visual snow. Every single person that can see will see this static effect and this static effect ISN'T VISUAL SNOW. Static in the dark is caused by light detecting proteins which are randomly set off due to heat in your retinal cells, since there isn't enough light your brain isn't able to adjust the signal to noise ratio so the static is apparent. When you are blinded by a flash of very bright light YOU WILL NOT BE ABLE TO SEE THE STATIC because the signal overpowers the noise too much. If you focus on any surface in any light condition you will be able to notice the "snow". I know because every single person I asked and I know a lot of people I told them to focus on a wall in normal light conditions and ALL of them SAW THE STATIC.

Those of you who have the real visual snow have it because your brain isn't able to adjust the signal to noise ratio due to an internal structural problem. You don't have visual snow unless it's so severe that it blocks out your ability to see fine details in normal light conditions.
