The Meaning of the Number of Blinks

  • We blink our eyes about twenty times per minute.


    Since one blink block our view about 0.3 seconds, we spend 6 seconds per minute in the dark(that is, 10% of our living hours).

    If you watch a two hour movie, you will miss about twelve minutes of the movie.

    However, since we naturally blink at breaks between scenes, we don’t feel a sense of discomfort.

    It is said that the reason why we blink is to moist the surface of our eyes, but the number of blinks we need for the moistening is only three times per minute.

    It has not yet been elucidated why we blink so many times.
