Anyone with at least half a brain knows this is ridiculously fast. Thats obviously incorrect
- seaal 2y agoForgive us Americans and being bad at metric. I personally wouldn’t have noticed the mistake, but I only have two brain cells. For other dummies, it should be milliseconds (1000x difference)
- vultour 2y ago400ms seems way too long for a blink. 300us is obviously wrong though.
- moritzruth 2y agoAccording to Wikipedia: > The duration of a blink is on average 100–150 milliseconds according to UCL researcher and between 100 and 400 ms according to the Harvard Database of Useful Biological Numbers. https://en.wikipedia.org/wiki/Blinking https://en.wikipedia.org/wiki/Blinking
- jprete 2y agoGP quoted "microseconds" i.e. 1000x smaller.
- kevindamm 2y agoMaybe it was intended to mean the time between neurological impulse to blink and the physical eyelid moving? Still, yeah, original text seems misleading. The 100-200 milliseconds duration of a blink was often cited in web development circles in the late 90s / early '00s, that I sometimes forget it isn't a widely known fact.
- spiralganglion 2y agoThey have a link to a source for that claim... and the source says 300 to 400 milliseconds. So whoever wrote and edited the OP article just messed this up.
