A real blink of an eye takes 300 to 400 milliseconds. Since there’s 1000 milliseconds in each second, a blink of an eye takes around 1/3 of a second. Compared to the time span of one full second, a blink of an eye is an eternity.

What’s the average blink rate of a human eye? Most authors, including those mentioned in the excellent overview of blink rate research from Stern et al. (1994), conclude that blink rate is a robust measure that increases with time on task and fatigue. Blink rate exhibits average values of 3–7 blinks per minute during reading and 15–30 during most nonreading tasks.

How long does it take for a human eye to blink? The average time it takes for a complete human blink is about 300 to 400 milliseconds or 3/10ths to 4/10ths of a second.

How old is the universe in the blink of an eye? That means that any event that happened over a 54,000-year period would occur in the “blink” of an eye, astronomically. Humanity’s tenure, with respect to the age of the universe, is close to a “blink.” We’re only three to four blinks old. That means, if the universe wasn’t paying attention, we could have snuck up on it.
