rpozarickij cover my non-dominant eye completely (that no light reaches it at all) then I start getting very strange visual artifacts in my non-covered eye. My vision becomes grainy (something similar to an old TV static), but that graininess appears in waves. Very unusual feeling.
I have a similar thing but a bit different, regardless of which which eye I cover, on the covered eye's side (like on top of the area that is now completely closed) starts getting really grainy but the interesting thing is that it changes based on which screen I use
if I use iPhone SE (iOS 17, it has the most dithering i've ever seen on a phone) it gets REALLY grainy
if I use iPhone 14 Pro (iOS 16, 480hz PWM) there is some grain but not much
If I use a 100% usable screen (1st gen Moto G from 2013 on Android 5.1) there is pretty much no grain at all
Also no grain at all if I'm not looking at a screen
Seems to connect to dithering 👀
