"Visual Snow" - what is it exactly?

[Chrysalis]

They are placed randomly, but evenly spaced out. It's hard to explain whether they move or not. It's hard to focus on only one. They don't seem to move in any direction, but they phase in and out I think? Like an old tv channel that's all static.

Is it all over your field of vision, where ever you look or is it more confined to a certain area? There is a neurological condition called visual snow too that causes a visual field that resembles static on a tv screen. I don't know much about it though.
