About 12 times per minute, unless you're me. Then you blink once every 78 seconds.

I don't blink every 78 seconds because that is false. I went a whole day without blinking.

You think your eyes are open, the are not because they are blink so fast that you can't see. so it is like 3 blinks in five nanoseconds. do the math.

@114960: if you didn't blink every 5 nanoseconds, they eyelids would be closed and they wouldn't open. Also it keeps dust particles, out of they eyes if you were blinking every 5 nanoseconds. The proof is there, ask a eye doctor and they will tell you that the eye blinks so fast that you can't see it.

What he means is that the eye can blink about 3 times simultaneously in 5 nano seconds.(10 ^ -9 seconds )... : P
