    Abstract: In a system and method for performing tear film structure measurement and evaporation rate measurements a broadband light source illuminates the tear film and a spectrometer measures respective spectra of reflected light from at least one point of the tear film. A color camera obtains a large field of view image of the tear film so as to obtain color information for all points of the tear film imaged by the color camera and an autofocusing mechanism focusses the color camera and the spectrometer. A processing unit coupled to the camera and to the spectrometer calibrates the camera so that the color obtained by the camera at the at least one point measured by the spectrometer matches the color of the spectrometer at the same point, and determines from the color of each point of the calibrated camera the thickness of the lipids at the respective point.
