@Danpiker This is trippy as hell! I also feel like the border is more distinct when it's purple, but I can't really check because they all turn purple when I look at them! 🤯
@Danpiker OK, so now, looking at it on my phone, they're all purple! And the one I look at is only slightly darker purple. Wild stuff.
-
@Danpiker TIL (from someone who said "this doesn't really work") - this doesn't work if your phone has a blue-light-blocking filter on it!
-
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.
Didnt see it until I put my phone back a lil further from my face. Cool!

@Danpiker this is absolutely wild! It definitely works for me

@Danpiker minimally, but the dots hurt because at the boundaries there are flecks greyish-whitish visual noise
-
@Danpiker i don't see it

Using my laptop with no night mode or colour blocking, it doesn't work for me. Maybe some brains are wired differently.

@Danpiker oh that one is cool! I also have never seen this particular one.

@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!

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

@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.
-
@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 Oh, wow. It does, and incredibly quickly and intensely, too.
-
@crazyeddie @wcbdata I found the effect was visible on one of my dual monitors, a new one, but not on the old one.
