I can both see it and "unsee" it. If I'm actively doing something and using my eyes for things I don't notice. But if I'm just sitting listening to music or whatever I can notice the "fuzz" and noise. In low light it's a very fine grain. In daylight it's a coarser pulsing of white and black.

I've always thought this was normal. I've asked a couple other people and they've said they see it too, :shrug:
