Why do we see “fuzz” or “TV static” when we close or eyes, or even when we have them open in a dark room?
In: Biology
Look at videos about frequencies on a metal plate, and running water. Also what frequency on the spectrum are colors and such. I have a theory, we can still see without our eyes, it is just we never learn how to. So you are seeing all the different overlapping frequencies in one bundled view.
Go stare at a hobo. Most people will see that they have “nothing” when in fact, the hobo is rich with the items high society casts away as “trash”
Because your eyes are constantly seeking stimulii. Your brain is not used to having a blank sheet, or in this case a black room.
The same thing happens staring at a blank white sheet of paper. You start to see green and purple hues that disappear when you shift your gaze
Is this real ? I just see black when I close my eyes I thought everyone did. What do other people see ?
Cameras, both technical and biological (eyes) produce a certain amount of visual noise. The noise has its own fixed “brightness” and quickly gets drowned out if the actual image you are looking at is bright enough. That’s why the noise is most pronounced when you look at / film something that is completely black. The noise happens because the tiny parts of the camera that turn light into an electrical signal get triggered accidentally by random motion of atoms. The transport and processing of the image signal can also introduce noise and other artifacts; this is very well understood for technical cameras but the exact way the brain processes images is only understood in broad terms.
