CN V - Corneal Reflex

The corneal reflex, also known as the blink reflex, is an involuntary blinking of  the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), or bright light, though could result from any peripheral stimulus. Using an interactive activity, the user can test whether the patient perceives the stimulus of the cornea or not.
