@mhwombat @Danpiker mine as well. Eventually even the center dot disappears and it’s just a hazy purple background.

@Danpiker Yep, immediately. Do I have a super power?

@Danpiker All the dots look purplish to me anyway. Perhaps very very slightly.

@Danpiker What is cool that I don't see the effect with my blue-mirrored transition glasses but can see without.

@Danpiker

The longer I look at a particular dot the more the other dots disappear completely into the blue background, although that last remaining dot doesn't turn more purple.

If I look at the whole field I can also see faint green shadow dots that move as I move my eyes, and which also disappear into the background.

@Danpiker I had the same issue as others, of being unable to look Only at one dot. When I stopped trying and just let my vision kind of skate between them though, they All started turning purple, which was cool. (Will mention I have both visual processing junk and non-Blind visual disabilities, but maybe anyone who switched focus often enough would get this?) ... Now I'm trying to figure out how to determine the periodic exposure necessary to maintain purple for all, oh no! ...rolls nerdily off

@Danpiker This worked for me. Sometimes two or three dots on the same row would appear purple. If I keep my focus fixed on one dot the others often disappear.

@claudius @Danpiker For me, it's even more weird. If I focus on one of the dots, all the other slowly fade out until it's completely blue, except the one I'm looking at.

@crazyeddie @wcbdata I found the effect was visible on one of my dual monitors, a new one, but not on the old one.

@mwichary @Danpiker Same. My experience is super trippy, close or far. The effect is immediate and distinct when I move my eye. Could be all that time staring at the sun.

@TrueNorthSpice @itgrrl It can be about your electronics, too. I can see the effect on my new monitor, but not on my old one.

@Danpiker Aha! It did not work for me on my old 2010-era emachine monitor, but when I dragged it over to my brand-new Asus monitor the effect was immediately noticeable.

Edit to add: On the older monitor, the color of the dots matters a lot more on my angle to the graphic. My first thought was that the top row looked much lighter! But that changed if I lifted myself a bit higher.

@Danpiker Who installed this eye tracking software on my phone without permission?

@Danpiker I love this. I know I have low blue macular sensitivity because blue neon signs at night have always been blurry to me to read. But it's cool to map the actual size - blotchy on retina, not a defined spot, redder areas in the purple circle. Thanks for sharing, and readers for further links!
