What is the Function of the Blink Reflex?

The blink reflex, which is also known as the corneal reflex is the reflex that is designed to ensure that your eyes do not get injured and occurs when soemthing rappidly approaches teh eye causing the rpaid oppening and closing of the eyelids.

The corneal reflex is driven by the autonomic nervous system and is not controlled by the human desire/thought process. This means that the spasm/ corneal reflex is involuntary, and will occur no matter how much a person is trying not to.

The corneal reflex is a good method of determining if a patient is  “faking” a seizure or not.
