How fast is my face?

Question

When we blink, approximately how fast are our eyelids moving?

Preferably in miles, or kilometres per hour.

Answer 1

I have no idea, but interesting Question!

Answer 2

An eye blinks at 300 to 400 hundred ms (milliseconds) per blink.  The average eye is 24 mm (millimeters). So it is between .06-.08 mm per ms.   Or 0.2 - 0.29 km/hr  or  0.12 - 0.18 mi/hr.  Really slow for a car, but very fast for your eye.  The eye lid does not travel very far. Very interesting question

Answer 3

On average, your blink takes about 3/10th to 4/10ths of a second.  The human eye is about 2.5cm.

2.5cm / (3.5/10 s) = 7.14285714 cm/s

Converted into other units:

About 0.2-0.3 km/hr (0.257142857 km/hour)

About 0.1-0.2 miles/hr (0.159781164 miles/hour)

I'm kind of surprised--it certainly feels like they're going a lot faster.
