Gregory's Serverhuman eyes have a refresh rate and these images screw with the jitter motion that creates it (it's somewhere around 200fps)
one of the symptoms of type 2 diabetes and excess alcohol consumption (which usually probably is caused by the sugar in the drinks) is double vision, this is where the super fine motion of the aiming muscles of the eyes doing that jitter stops working properly, and you start to see two images of everything overlapped by what looks like about 1mm at a distance of 3 feet or so
that natural jitter is how these optical illusions work
in eastern europe a very common thing you see around roads is poles painted with zebra black and white stripes, and you notice as you move past them that in the peripheral vision they flicker and grab your attention, same thing here
in airports also, you see lots of buildings painted with high contrast usually red and white checkerboard patterns... same reason... the eyes are moving back and forth and this causes a dazzle effect that disrupts your recognition of what you are looking at and grabs your attention
i believe, in fact, that zebras stripes exist specifically to confuse their prey, there is probably other examples of natural dazzle patterns especially in prey animals like lizards
