Blepharospasm is often associated with dry eyes, but the causal mechanism is still not clear.

The blink of the eye which is the reflex of the orbicularis oculi muscle was found to have a latency of about 20 to 40 milliseconds. Out of larger body parts, the head is quickest in a movement latency in a range from 60 to 120 milliseconds. The neck then moves almost simultaneously with a latency of 75 to 121 milliseconds.

Stimulation should elicit both a direct and consensual response (response of the opposite eye).
