Description : “The human eye blinks an average of 4,200,000 times a year.”
Last Answer : That's 15-20 times per minute. That's up to 1,200 times per hour and a whopping 28,800 times in a day - much more often than we actually need to keep our eyeballs clean and ... because the brain enters a momentary state of wakeful rest when we blink, and leaves us more focussed afterwards.
