>To see Haidinger’s brushes for yourself, look at a blank white portion of an LCD screen on a computer, tablet or phone.
Holy crap, it worked! They're very very very faint, and if your monitor ins't clean, they're easy to miss. They appear right where you're looking at. If you imagine two lines coming out of your eyes at the screen, they show up right where the lines converge. Very faint and pale yellow, almost looks like a fading after-image.
Only saw them when I rolled my head left and right / up and down. Imagine pointing one ear towards the floor and the other towards the ceiling - I oscillated between these two positions and saw it.
It was harder to see when I unfocused my eyes like I was going to look at a 3D picture. Easier to see when focusing on the spot in the screen I'm looking at.
