Blink Reflex

Your eyes are fragile little orbs. They must be protected! Thankfully, we have eyelids and a blink reflex which ensures that we close our eyes the instant a threat is perceived. Fun fact: We blink an average of once every 3–4 seconds. Blinking helps distribute tears over your eyeball in order to keep it nice 'n moist (and to wash away bacteria and other foreign particles).
