How often does a person blink on average?
Everybody blinks a lot. A person blinks about 15 times per minute - it means that we have our eyes closed for 10 percent of our waking hours. We blink a lot in order to protect our fragile eyeballs from dust and to lubricate them. Nevertheless, scientists offered up another idea. They think that the process of blinking somehow helps an individual to focus on the surrounding objects!
