Abstract
An imaging system captures one or more images at a time when a subject is comfortably wearing a pair of glasses with dummy lenses. The subject's face is illuminated by energy sources (e.g. visible light sources), and specular reflections ('glints') from the dummy lenses used to measure the locations the dummy lens(es). This provides information about how the comfortable positions for glasses on the subject's face, which can be used to design and fabricate personalized glasses.
