I searched on Internet in order to find answers for your interesting question. Adults blink at different frequencies depending on their activity. When concentrating, blink rates decrease; when at rest, blink rates increase. An average adult can blink six times per minute, which means a total of around 8,640 times a day!

Little children blink less than an adult; the reason we blink is because the tears that lubricate our eyes evaporate after a few seconds, which brings the reflex of blinking again, in order to keep our eyes constantly lubricated.
