Every time you blink, your eyelids spread a cocktail of oils and mucous secretions across the surface of the eye to keep your globes from drying out. Blinkingalso keeps eyes safe from potentially damaging stimuli, such as bright lights and foreign bodies

➡️Eyes blink to keep their surfaces moist and free of debris – and to protect themselves from damage.✔️
➡️Blinking is a natural reflex that occurs when a foreign body threatens to fly into the eyes, or when a person is startled or exposed to a bright light.✔️
➡️Even a loud sound can activate the blink response – also known as the corneal reflex.✔️
➡️Doctors sometimes test the blink reflex during a neurological exam by touching the corner of the eye with sterile cotton.✔️
➡️Normally both eyes blink or shut even when only one cornea is touched, which is called a consensual response. ✔️
➡️If there’s damage to the fifth or seventh cranial nerves, the corneal reflex may be absent, or the response may not be consensual.✔️
