Answer 2

Answer:

The average person blinks every 4 seconds – that is about 15 times per minute, or over 20,000 times a day, depending on how long the person stays awake. Each blink lasts about a tenth of a second, which isn't a lot of time. But it is enough to clean and lubricate the surface of the eye.
