Does anyone else NOT have a bit of mild image noise in their vision at all times that gets stronger in the dark, just like a camera except it's ultra HD fine-grained? Checking because there's a thread on Reddit with a bunch of people claiming that seeing that image noise isn't universal. 😮
@banjofox If you look at live analog video, old 8/16 mm film, or the local video preview from a cheap webcam, there is often snow/grain/static embedded in the picture. Little "atoms" that dance around randomly. Some of us have that in our vision. It's especially easy to see if you stare at a flat surface like a white ceiling or wall, or if you're in a dark room.
@banjofox Floaters are different. They look like little amoeba that seem to float in your field of vision, especially visible when looking up at a blue sky. They don't flicker but can dance around a bit.
The phenomenon I'm talking about is documented on Wikipedia as visual snow. Here's a simulation: https://visionsimulations.com/visual-snow.htm
It's easiest to observe at night in indoor lighting, or simply by switching off the lights.
