Each blink lasts between 0.1 and 0.4 seconds. Given how many times the average person blinks per minute, this makes up about 10 percent of the time you’re awake. Research suggests that there’s no significant difference in how often you blink based on your sex or your age.
Blinking is essential for the eye’s health because it for clearing debris from your eyes, like small particles from the air, dried tears, and dead cells, bringing nutrients and other substances to your eyes that help keep them healthy, wetting your eyes, which prevents dry eyes and reduces your risk of problems with your tear film, and bringing oxygen to your eyes.
All of these functions also help prevent eye infections. Additionally, blinking lets your brain briefly rest, helping you refocus on whatever it is you’re doing.
If you don’t blink, or don’t blink frequently enough, your cornea can swell, doesn’t have blood vessels, so it needs oxygen from the tear film, which it gets when you blink. Your eyes won’t get the nutrients they need to stay healthy.
Also, your eyes can dry out, because your tear film isn’t being replenished. This can lead to eye pain and blurry vision, and your risk of eye infection increases due to debris that stays in your eye and a lack of oxygen to the eye.
