Another day, another optical illusion involving disappearing dots.
An unusual illusion is forcing some Internet users to question whether they’re going blind or not. It shows an animated rotating grid with dots that “disappear.”
The illusion, according to The Independent, is the result of a phenomenon called motion-induced blindness, which is still being studied by scientists.
To produce the effect, one has to stare at the flashing green dot in the middle of the image. After a few seconds, some people have noted that some or all of the yellow dots fade or disappear completely.
“In motion induced blindness (MIB), salient objects in full view can repeatedly fluctuate into and out of conscious awareness when superimposed onto certain global moving patterns,” says a 2008 study by Yale researchers, per The Telegraph.
“Rather than being a failure of visual processing, MIB may be a functional product of the visual system’s attempt to separate distal stimuli from artifacts of damage to the visual system itself.
“When a small object is invariant despite changes that are occurring to a global region of the surrounding visual field, the visual system may discount that stimulus as akin to a scotoma, and may thus expunge it from awareness.”
