Abstract: A method utilizing thermograph of a tear film for generating a quantified index includes steps of: capturing a set of tear film thermograph data, deriving parameters from the set of tear film thermograph data, and executing a synthesis calculation based on the derived parameters. The parameters include a temperature distribution of each tear film thermograph, a temperature fall tendency of an open-eye tear film during time variation, a type of a tear film break-up and an occurring time of the tear film break-up, and an upward drifting speed of a temperature color block in the tear film thermograph. The parameters represent the quantity of the aqueous volume of the tear and the stability of the tear film for establishing a reliability of an examination of a diagnosis of a dry eye disease without intruding into a testee's eye.

Abstract: A method of using infrared thermal imager to diagnose eye diseases including the dry eye syndromeuses an infrared thermal imager to take the surface image of the eyeball of the patient. Temperature variation at a specific position of the cornea of the eyeball is precisely measured in a unit time. An attenuation coefficient K of a temperature dropping curve and a temperature difference ?T are obtained from the temperature variation. Optimized curves of K and ?T are provided for the doctor to diagnose the patient's eye disease.
