At least a portion of a surface of the tear film is illuminated using a broadband light source. A spectrum of light of the broadband light that is reflected from at least one point of the tear film is measured, using a spectrometer. Color information for a plurality of points of the tear film is obtained, by imaging a field of view of the tear film using a color camera. Using a processing unit, data from the color camera and data from the spectrometer that are indicative of characteristics of the tear film are received, and based upon a combination of the data received from the color camera and the data received from the spectrometer, an output is generated that is indicative of a structure of the tear film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for performing tear film structure measurement","description":"Apparatus and methods are described for performing structure measurement on a tear film of an eye of a subject.
