Analysis of the BLINK PATTERN is an important feature of Ocular Surface and Tear Film investigation- but this is typically not supported by available devices. Blinking is of utmost importance for the correct formation of the pre-ocular tear Film and its lipid layer (TFLL) because even a sufficient amount and delivery of lipids from the Meibomian Gland does still not render an intact and stable tear film when the blink pattern is disturbed and e.g. partial blinks occur. Partial blinks are difficult to record manually in particular when the patient is aware of this. Much easier and more reliable is an automatic recording of the blink pattern together with investigations suh as lipid layer thickness, as seen here with the Lipiview, or of  N on- I nvasive  B reak- U p  T ime ( NI-BUT ).
