    @Danpiker Oh, wow. It does, and incredibly quickly and intensely, too.

    @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.

      @wcbdata @Danpiker Using a laptop. Yoga 910. Quick duck search leads me to believe there's no such filter on its screen. My night light shift software isn't on.

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

        @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.

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

              This illusion was new to me. Does whichever dot you look at turn more purple?

              Pretty neat how clearly this lets you see the reduced sensitivity to blue light in the very centre of your vision.

              @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.

                @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

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

                              @Danpiker For me, the dot that I'm looking at doesn't change, but the remaining dots fade into the background.

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