The eyelids are not only provide physical protection of the ocular surface, but also have a significant role in homeostasis of the ocular surface by performing blinking [1]. Blinking is a vital function of the eyelids which redistributes the tear film and stabilizes the ocular surface [2]. Mechanism of blinking is precisely regulated [3] which is important in temporarily boosting the visual performance [4]. Ineffective blinking leads to unstable tear film and ultimately to several ocular surface diseases including dry eye disease [2]. Examples of dysfunctional blinking are incomplete blinks, high blink velocity, short blink intervals, forceful blinking, and low (<10/min) or high (>25/min) blink rates. The changes in blinking quality and rate could be (1) a response to ocular surface diseases, e.g. dry eye disease, or (2) primarily originated from neurologic or systemic diseases, e.g. benign essential blepharospasm or Parkinson’s disease which leads to ocular surface and tear film destabilization [5,6].
