How many times do blink a day?

Answer 1

The average infant only blinks once every minute or so, but adults can blink at varying frequencies between three to fifteen times per minute depending upon activity. For adults, this will produce a total of around 10,000 blinks per day.

When concentrating or actively processing input, blink rates decrease; when reading, for example. When at rest, blink rates increase. Higher blink rates can also signify anxiety, deceit or a lack of restful sleep. Dust, bright light and other environmental conditions that may induce eye-strain can dramatically increase blink rates, as can viral and bacterial infections that affect mucous production and lacrimal function.

If the average adult blinks around three to fifteen times per minute and is awake for sixteen hours of the day, they blink between 2,880 and 14,400 times per day, probably averaging about 9,600 (ten per minute).
