WARNING--CLICKING ON THIS LINK WILL LEAD YOU TO AN INTERESTING ARTICLE BUT WHOSE HEADLINE REALLY IS TOO CUTE AND DOESN'T HAVE A SCIENTIFIC PANACHE. IT POSSIBLY IS DESIGNED AS SUCH TO GET PEOPLE TO CLICK ON IT BUT I CANNOT SCIENTIFICALLY PROVE IT.
This is TOO interesting to pass up. It has always been one of those anecdotal questions on my mind, and some scientist turned it into a study. Why don't I notice it when I blink? Here are the four paragraphs and you can get the idea without the BBC headline--
http://news.bbc.co.uk/1/hi/health/4714067.stm "The team from University College London found the brain shut down parts of the visual system for each blink.
Writing in Current Biology, they said this was the case even if light was still entering the eyes.
The researchers said this could explain why people do not notice their own blinking, as it gave us an "uninterrupted view of the world".
A blink lasts for between 100 and 150 milliseconds. We automatically blink 10 to 15 times a minute to moisten and oxygenate the cornea."
