METHOD AND OPTICAL APPARATUS FOR CONTINUAL MONITORING TEAR FILM INTEGRITY OF EYE

Abstract

Disclosed is a method for continual monitoring of a tear film integrity of a user's eye (300). Method comprises determining a blink pattern of user's eye, using a means for detecting blinks of user's eye; measuring a temperature of an ocular surface of user's eye, at a set of at least two time instants within an inter-blink time interval of user's eye, using at least one temperature sensor (204A, 204B, 302); determining a rate of change in measured temperature for set of at least two time instants, based on a time interval between set of at least two time instants; comparing rate of change in measured temperature with a first threshold value; and when rate of change in measured temperature is greater than first threshold value: deeming tear film integrity of user's eye as broken.
