Optical method and device for determining blood glucose levels

摘要: Blood glucose levels of a person are determined by device (1) which provides changing light pattern changes in regard to one or several parameters defining its luminance, color, rate flicker, spatial contrast, detail content, speed, otherwise, provided that the change gradually stimulates retinal system more than another system. A observes until subjective visual effect occurs, is preferably an observer perceives dramatic appearance pattern, for example, perceived direction rotation. The indicates specific ration stimulation two systems, point balanced systems. Upon noting effect, patient actuates mechanism (4, 5) parameter values with corresponding blood level using predetermined calibration data. Thereby, person's accurately completely non-invasive manner.
