Blepharospasm is often associated with dry eyes, but the causal mechanism is still not clear. [16] [8] Research in New York and Italy suggests that increased blinking (which may be triggered by dry eyes) leads to blepharospasm. [24] [25] A case control study in China found that blepharospasm aggravated dry eyes. [26]
Blinking is a bodily function; it is a semi-autonomic rapid closing of the eyelid. [1] A single blink is determined by the forceful closing of the eyelid or inactivation of the levator palpebrae superioris and the activation of the palpebral portion of the orbicularis oculi, not the full open and close.
The corneal reflex, also known as the blink reflex or eyelid reflex, [1] is an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), though it could result from any peripheral stimulus. Stimulation should elicit both a direct and consensual response (response of the opposite eye).
EOG is a technique for measuring the resting potential of the retina in the human eye. [32] Eye-video test: Measures eyes blinking and eye movements to detect microsleep events. [33] [34] Mouth yawning test: Counts number of yawns over a period of time. [35] Speech tests: Examines emotions and/or prosody in speech to predict microsleep episodes ...

[15] [16] Those experiencing severe symptoms can also utilize behavior techniques such as repeated blinking during hallucinations, rapid eye movement from one object to another and bright lighting to engage the visual neural pathways.
